PUBLIC HEALTH LAWS In Ontario, there are many laws designed to protect our health. Two of these laws are: 1)

Health Protection and Promotion Act

The Health Protection and Promotion Act is a provincial law. It applies to all of Ontario. This Act gives powers to Public Health Inspectors. It allows them to do things like: inspections, investigate complaints, take food samples, condemn food and close food premises. As defined in the Health Protection and Promotion Act, the operator of a food premises is responsible for maintaining and operating the food premises according to the regulations

2)

Food Premises Regulation

The Food Premises Regulation is also a provincial law. This regulation contains the minimum health standards for all food premises in Ontario. It includes things like: what temperature foods must be cooked to, how food is to be stored and prepared, what equipment is necessary, and the hygiene requirements of food handlers. Public Health Inspectors follow the Food Premises Regulation when doing their inspections. As defined in the Food Premises Regulation, an employee of a food premises must follow the standards and requirements of the regulation

THE ROLE OF PUBLIC HEALTH INSPECTORS Public Health Inspectors work for and are employed by your local Health Department and have the duty and the authority to enforce the Food Premises Regulation. Public Health Inspectors inspect food premises such as restaurants, food take-outs, cafeterias, grocery stores, daycares, hospitals, nursing homes, homes for the aged and other public eating places for compliance with the requirements of the Food Premises Regulation.

Public Health Inspectors ensure that food is safely prepared, stored and served for the general public. Public Health Inspectors examine records and ensure that foods being used in food premises are from government inspected sources.

Public Health Inspectors investigate complaints like reports of food poisonings and have the authority to close a food premises when a health hazard is present. Public Health Inspectors educate people and provide food safety information and training. Public Health Inspectors also inspect and investigate complaints at other types of places for public health reasons, which includes (but is not limited to) public swimming pools and spas, daycares, and private drinking water systems (water wells). Food Handler Certification Course Study Guide

Page 8 of 162

FOOD SAFETY INSPECTIONS There are two types of food safety inspections:

1)

Regulation Compliance Inspection

The purpose of this inspection is for the Public Health Inspector to check the food handling and general maintenance and sanitation of the food premises according to the Food Premises Regulation. This includes checking for proper temperature control, food handler hygiene, the cleaning and sanitizing of utensils, pest control and overall building maintenance. No appointment is made for a regulation compliance inspection; they are surprise inspections. Following the inspection the Public Health Inspector will give the owner and/or operator a written report of their inspection findings that outlines corrections, if any, that need to be made along with a date that the corrections are to be completed. In the Region of Peel, the Public Health Inspector will also issue a PASS, CONDITIONAL PASS or CLOSED sign based on the inspection findings. The owner/operator is required to post the sign at or near the public entrance. The inspection findings will also be posted on the website: “www.foodcheckpeel.ca”. The sign and the website allow members of the public to know how well a food premises did on their previous inspections.

2)

HACCP (Hazard Analysis Critical Control Point) Audit

The HACCP audit focuses on the flow of food from receiving to service. The Public Health Inspector will “audit” the preparation of a hazardous food item from the menu or a food that could potentially be involved in foodborne illness. The Public Health Inspector will also concentrate on the Critical Control Points during the food preparation. The HACCP audit confirms that the foods prepared at a food premises are prepared the safest way possible. → You will learn more about the HACCP system in Chapter 7 of this workbook How often will a food premises be inspected? How often a food premises is inspected depends on the level of risk the Public Health Inspector gives it. The level of risk depends on: the number of preparation steps for a food item types of foods prepared population served history of possible or confirmed food poisoning

Three Categories of Risk High risk – four (4) or more inspections each year. These food premises prepare hazardous foods and meet one of the following criteria: Serve a high risk population based on age or medical condition. For example, nursing homes, homes for the aged, hospitals and most child care centres serve high risk populations Use processes involving many preparation steps (such as cooling and reheating), and prepare foods frequently associated with food poisonings. For example, buffet restaurants, banquet facilities and catering operations

Food Handler Certification Course Study Guide

Page 10 of 162

Moderate risk – two (2) or more inspections each year. These food premises meet one or more of the following criteria: Prepare hazardous foods without meeting the criteria for high risk. For example, fast food restaurants, submarine sandwich shops and pizza takeouts Prepare non-hazardous foods that are subject to extensive handling or are prepared in high volume. For example, bakeries and butcher shops Low risk – one (1) or more inspections each year. These food premises do not prepare hazardous foods but meet one of the following criteria: Prepare and/or serve non-hazardous foods without meeting the criteria of moderate risk Used as a food storage facility Serve pre-packaged hazardous foods. For example, convenience stores, food banks, refreshment stands, catering vehicles, foodprocessing plants, milk depots and cocktail bars

Remember! The main purpose of a food premises inspection conducted by a Public Health Inspector is to prevent foodborne illness

CHAPTER 2 Introduction to Food Safety, Micro-organisms and Contamination

Food Handler Certification Course Study Guide

Page 15 of 162

CONTAMINATION Food may become unsafe when harmful things get into it. This includes: biological micro-organisms (bacteria, viruses, parasites, moulds and yeasts) chemicals physical objects → This is also called contamination

When can contamination happen? Contamination can occur: at the farm during delivery during storage during preparation during cooking during service when food is on display

Common Types of Food Contamination The three most common types of food contamination are: 1)

Biological Contamination: contamination of food with micro-organisms.

2)

Chemical Contamination: contamination of food with chemicals.

3)

Physical Object Contamination: contamination of food with physical objects.

→ We will look more closely at each of these types of food contamination

Food Handler Certification Course Study Guide

Page 16 of 162

1)

BIOLOGICAL CONTAMINATION

What are micro-organisms? → Micro means very small. → Organism means it is alive. Therefore, micro-organisms are very small forms of life. Bacteria, viruses, parasites, moulds and yeasts are all micro-organisms. Micro-organisms can be helpful or harmful Helpful micro-organisms are an important part of making foods such as yogurt, beer, cheese and bread. These micro-organisms are safe to eat. Harmful micro-organisms are also called pathogens. These micro-organisms are not safe to eat, and can cause the person who eats the contaminated food to become sick. Some examples of pathogens include: Salmonella bacteria, Hepatitis A virus and Giardia parasite.

Where are harmful micro-organisms found? Harmful micro-organisms can be found in or on the following places: Raw foods such as meat, poultry and fish Unclean food preparation equipment such as mixers, slicers, blenders, can openers, knives, pots and pans People especially a person’s hands, nasal passages, mouth and in their bodily wastes (feces, urine and sweat) Unclean work surfaces such as tables and cutting boards Insects such as cockroaches and flies Rodents such as mice and rats Air, soil and polluted water

Five Types of Micro-Organisms Bacteria Viruses Parasites Yeasts Moulds

Bacteria Bacteria cause the most foodborne illnesses in Canada. Bacteria are very small. If bacteria could be put side-by-side there would be 25,000 bacteria in 1 inch. What does bacteria smell and taste like? Bacteria generally do not have a smell and bacteria generally do not have a taste You cannot tell if a food has bacteria in it just by looking at the food. Bacteria cannot be seen unless a microscope is used. A food may look, smell and taste normal, but it can still have harmful bacteria in it. Examples of bacteria that cause foodborne illness include: Salmonella, Campylobacter and E. coli.

Viruses Viruses are smaller in size than bacteria. They can be found in: people, contaminated water or ice, raw fish and shellfish that are harvested in water contaminated with sewage, raw and unwashed vegetables and fruits fertilized with human waste.

Examples of viruses that cause foodborne illness include: Hepatitis A, and Norovirus. Food Handler Certification Course Study Guide

Page 18 of 162

Parasites Parasites are very small, microscopic living things. They can grow in your body, lay eggs and cause illness. Parasites can be found in undercooked wild meats such as bear and boar meats, and in raw fish. Parasites have also been found in some imported vegetables and fruits like lettuce and berries. Parasites can be killed by cooking the food item to an internal temperature of 74°C (160°F) for 15 seconds. Another method of killing parasites is by deep freezing the food item the parasite is found in. For example, fishing industries freeze fish at -20°C (-4°F) or below for a minimum of seven (7) days to kill parasites that may be found in it. As well, freezing fish at -35°C (-31°F) or below for a minimum of 15 hours will also kill the parasite.

Deep freezing fish can kill parasites

A picture of a Giardia parasite from a microscope

Examples of parasites that cause foodborne illness include: Giarida, Trichinella, and Cyclospora.

Yeasts Yeasts need sugar and moisture to grow. Foods containing a large growth of yeast may look slimy, or cloudy. Yeasts affect the quality of foods and can cause spoilage of jellies, jams and honey. For example, pickles may lose their crunchiness because of yeast. Yeasts generally do not cause illness

Food Handler Certification Course Study Guide

Page 19 of 162

Moulds Moulds can be seen as fuzzy growths on foods. They mainly cause food spoilage. Some moulds produce a poison (also known as a toxin) called a mycotoxin that cannot be seen.

Moulds can be seen as fuzzy growths on food

Soft foods such as luncheon meats, cooked leftovers, pasta, yogurt, sour cream, and bread (as seen in the picture below) should be thrown out and not eaten if mould growth is seen on them. If mould is seen on hard foods such as hard salamis, dry-cured country hams, and firm fruits and vegetables such as cabbage, bell peppers, and carrots, then you can eat the food as long as you first cut off at least 1 inch around and below the mould spot. Make sure to not contaminate the knife with the mould! What should you do if a hard cheese is mouldy? A hard cheese like cheddar can still be used if it has mould on it. Remove or cut about 1 inch (2.5 cm) around and under the mould. What should you do if a soft cheese is mouldy? A soft cheese like feta should be thrown out if it is mouldy.

Remember! Most foodborne illness in Canada is caused by Bacteria

What Do Bacteria Need to Live and Grow? i)

Hazardous Food

Bacteria grow best on foods that are high in protein and moist. These foods are called hazardous foods. Hazardous foods include any food that is found in whole or pieces of meat (raw or cooked), poultry (raw or cook), seafood (raw or cooked), cooked rice, cooked potatoes, eggs and dairy products.

ii)

Warm Temperature

Bacteria grow fastest in the range of temperatures between 4°C and 60°C (40°F and 140°F). This temperature range is called the temperature danger zone.

iii)

Time

Bacteria need time to grow. Bacteria grow fastest when hazardous foods are left in the temperature danger zone for more than two hours.

→ We will look more closely into what bacteria need to live and grow

Food Handler Certification Course Study Guide

i)

Hazardous Food

Foods can be grouped into two types: Hazardous and Non-Hazardous. Hazardous Foods Hazardous foods are foods that naturally have, or are easily contaminated with disease causing bacteria. Harmful bacteria grow best in foods that are high in protein, moist and a neutral pH. These foods are called hazardous foods. While almost any food can be involved in a foodborne illness, harmful bacteria grow more quickly in hazardous foods, which also support the growth of harmful bacteria easily. Hazardous foods need extra special care when being handled, stored and prepared. Examples of hazardous foods include: -beef -pork -chicken -turkey -milk and dairy products

-fish and seafood -gravy -eggs -cooked rice and beans -mixed salads (such as tuna, egg)

Non-hazardous Foods Non-hazardous foods are foods that bacteria do not grow well on. These foods are low in protein, dry or high in acidity. Examples of non-hazardous foods include: -flour -uncooked rice -sugar and pasta -canned foods -bread (unopened) -vinegar -pickles Food Handler Certification Course Study Guide

Warm Temperatures Different temperatures affect the growth of bacteria. Take a look at the chart below:

Remember! Very hot temperatures (74°C/165°F or higher) kill bacteria Hot temperatures (60°C/140°F or higher) stop the growth of bacteria and kills some types of bacteria The Temperature Danger Zone (4°C/40°F to 60°C/140°F) allows the bacteria to grow rapidly Cold temperatures (4°C/40°F or lower) slow down the growth of bacteria Very cold temperatures (-18°C/0°F or lower) stop the growth of bacteria, but the bacteria are still alive Food Handler Certification Course Study Guide

Let’s take a closer look at what happens to bacteria at different temperatures: At temperatures above 74°C (165°F), bacteria will die. 74oC →

At temperatures 60°C (140°F) and higher, bacteria do not grow and some bacteria will die. This is also called the Hot Holding Temperature. 60oC →

At temperatures between 4°C and 60°C (40°F and 140°F), bacteria grow rapidly. This is also called the Temperature Danger Zone.

The general food safety rule about temperature is that hazardous foods such as meat, poultry, fish, cooked rice, cooked potatoes, eggs and dairy products must be kept:

Hot at 60°C (140°F) or Hotter or Cold at 4°C (40°F) or Colder

Remember! Keep hot foods hot and keep cold foods cold Hazardous foods must not be kept in the Temperature Danger Zone

Food Safety Tip: Preparing A Salad Pre-chill all room-temperature salad ingredients in the refrigerator. This can include a can of unopened tuna, a jar of unopened mayonnaise, celery, lettuce and onions. This way the ingredients will already be cold while you work with them Thoroughly rinse all produce under cold running water Chill the cooked ingredients immediately after they are cooked and before mixing the salad. This can include chicken, eggs, pasta and potatoes The mixing bowl can also be refrigerated Putting the bowl on ice will help keep the salad cold when the temperature in the kitchen is hot

Measuring the Internal Temperature of Hazardous Foods The most important temperature measurement for food safety is the temperature of the inside of a food item. This is called the internal temperature of the food. It is important to check the internal temperature of a food to ensure that it has been held at the proper temperature to control pathogen growth. All food premises that store and/or prepare hazardous foods must have a working probe thermometer onsite for staff to check internal temperatures with. The internal temperature of food is measured by using one of the following: → metal stemmed analogue probe thermometer → digital probe thermometer → thermocouple

digital probe thermometer thermocouple metal stemmed analogue probe thermometer

These three thermometers are all types of probe thermometers Food Safety Tips: Using A Probe Thermometer 1) Insert the probe into the centre, or thickest part, of the food. Wait until the temperature read-out stops changing on the display 2) Measure the internal temperature in more than one part of the food 3) Do not let the probe touch the bottom or side of the container the food is in 4) Wash, rinse, sanitize and air dry the probe between each food item you measure. Use the same sanitizing solution used for dishes and utensils or an alcohol swab to sanitize the probe 5) When measuring the temperature of packaged foods place the probe between the packages Food Handler Certification Course Study Guide

Page 28 of 162

Taking Care of Your Probe Thermometer Thermometers must be cleaned and sanitized after checking the temperature of each food item to prevent contamination. Thermometers must also be adjusted to measure temperatures correctly. This is called calibration.

When do you calibrate? → when the thermometer is new → after it has been dropped → at least once a month or check the manufacturers’ recommendation

Calibrating A Metal Stemmed Analogue Probe Thermometer Fill a glass with ½ ice and ½ cold water. Place the probe into the glass, making sure it does not touch the sides or bottom of the glass. After a minute, the display should read 0°C or 32°F (this is the freezing point of water). If it is not at this temperature, turn the calibration nut located under the dial until the needle reads 0°C or 32°F.

Calibrating A Digital Probe Thermometer or Thermocouple Check the accuracy of a digital probe thermometer or thermocouple regularly using the ice and water method. If the reading is not at 0°C or 32°F, try changing the battery. If that does not work, have the thermometer checked by the manufacturer or buy a new thermometer.

Food Handler Certification Course Study Guide

Thermometers for Refrigerators, Freezers, and Hot Holding Units Refrigerator, freezer and hot holding unit thermometers measure the air temperature inside the appliance and not the internal temperature of food items. These thermometers are used to indicate if the appliance is working properly. Under the Food Premises Regulation each cold and hot holding unit must have a working thermometer in it so that staff can check that the units are working properly. Refrigerators often break down – never assume that your refrigerator is working properly, so always take the time to check the temperature. It is recommended that all refrigerators and hot holding units have their air temperatures checked at least twice a day and that you record these temperatures on temperature record log.

Refrigerator Thermometers

Oven Thermometer

Refrigerator thermometers and oven thermometers should be placed near the door as this is where the temperature will be the warmest in a refrigerator and coolest in a hot holding unit and oven. All refrigerators, freezers, and hot holding units must be equipped with working thermometers.

iii)

Time

In addition to food and temperature, bacteria also need time to live and grow. Bacteria grow best on hazardous foods left in the temperature danger zone. The longer the hazardous foods are left in the temperature danger zone, the more the bacteria multiply. This means the time spent preparing or storing hazardous foods in the temperature danger zone should be kept to a minimum.

Bacteria double in number every 10 - 20 minutes in the temperature danger zone Food Handler Certification Course Study Guide

Page 30 of 162

When bacteria multiply to large numbers in food, that contaminated food may make a person sick if they eat it. The pictures below show how quickly one bacterium on a hazardous food can grow if left in the temperature danger zone for two hours and 45 minutes:

Hazardous foods should not spend more than two hours in the temperature danger zone. This includes time during: → Delivery → Storage → Preparation → Holding → Displaying → Serving

Remember! Most foodborne illnesses from Biological (micro-organism) Contamination involve hazardous foods being left in the temperature danger zone for more than two hours

Food Handler Certification Course Study Guide

Page 31 of 162

2)

CHEMICAL CONTAMINATION

Chemical contamination can occur from a variety of sources. Some foods are exposed to chemicals while they are growing, such as pesticide use on produce, and others have chemicals added to them for flavour, as is the case with MSG (monosodium glutamate). Chemicals, such as cleaning supplies, can also be accidentally added to foods. As well, food being stored in improper containers can have chemicals transferred onto the food. To help prevent chemical contamination: Store food in food grade containers. Acidic foods such as ketchup, and apple juice should never be stored in an open can. After opening a can of acidic food it is important that you transfer the remaining contents into a food grade container Store all cleaning supplies away from food and food contact surfaces

3)

PHYSICAL OBJECT CONTAMINATION

Physical objects such as broken glass, hair, bandages, insects or pieces of equipment can contaminate food.

Fly in a can of vegetables

Machinery in a frozen treat

To help prevent physical object contamination: Do not store food in breakable containers such as glass Do not store glass or other breakable items near food preparation surfaces Do not eat, drink or chew gum while working If you are wearing a bandage on your hand while preparing food, ensure that you wear a clean, disposable glove on that hand to prevent the bandage from accidentally falling into food Food Handler Certification Course Study Guide

CHAPTER REVIEW The three most common ways that food becomes contaminated are through: Biological (micro-organism) Contamination, Chemical Contamination, and Physical Object Contamination Harmful micro-organisms are also called pathogens Five types of pathogens are: bacteria, viruses, parasites, moulds, and yeasts Bacteria cause the most foodborne illness. Bacteria need three things to live and grow: hazardous food, warm temperature, and time Hazardous foods are foods that are high in protein and moist Internal temperatures of foods are measured using a probe thermometer The temperature danger zone is the range of temperatures between 4°C to 60°C (40°F to 140°F). Bacteria double in number every 10 - 20 minutes in this temperature range If a hazardous food item is to be kept hot, it must be kept at an internal temperature of 60°C (140°F) or hotter. This is called the hot holding temperature If a hazardous food item is to be kept cold, it must be kept at an internal temperature of 4°C (40°F) or colder. This is called the refrigeration temperature Notes:

CHAPTER 3 Contamination of Food

Food Handler Certification Course Study Guide

Page 35 of 162

CONTAMINATION OF FOOD As seen in the last chapter, when something harmful gets into food it is called contamination (also called cross-contamination). Contamination occurs when a harmful thing or substance already on a surface or food are transferred into or onto another food item. Contamination can happen in different ways: 1)

Contaminated food item comes into contact with another food item. This is also called Food to Food Contamination. For example, raw chicken juices dripping onto a cooked chicken stored in a refrigerator.

2)

Contaminated equipment comes into contact with a food item. This is also called Equipment to Food Contamination. For example, the same cutting board is used to cut raw chicken and to cut tomatoes and lettuce for a salad without being cleaned and sanitized in between.

Equipment to Food Contamination

3)

Contaminated people come into contact with a food item. This is also called People to Food Contamination. For example, a food handler with dirty hands touches food or someone coughs or sneezes directly onto food. → We will look more closely into these three types of contamination

Food Handler Certification Course Study Guide

Page 36 of 162

1)

Food to Food Contamination

This is when harmful micro-organisms (pathogens) are transferred from a contaminated food item to another food item. Some examples of this include: raw meats or poultry juices dripping on cooked or ready-to-eat foods in the refrigerator; raw eggs in an eggnog drink or salad dressing; mixing leftover food items with freshly made food; or, mixing raw food ingredients with food that is already cooked.

Safe Storage

Unsafe Storage

To prevent food to food contamination in the refrigerator: Store raw foods with dripping juices on the lower shelf. For example, raw beef or raw chicken Store cooked foods or foods to be reheated on the middle or higher shelves. For example, cooked beans or leftover casserole Store food that is ready-to-eat on the highest shelf. For example, a green salad Cover or wrap all food items Store each type of raw meat in its own container Ready-to-eat foods

Equipment to Food Contamination

This is when contaminated equipment transfers harmful micro-organisms (pathogens) to a food item. Some examples of equipment that may be involved in contamination include: cutting boards, chopping blocks, work tables, knives, blenders, slicers, grinders, mixers, can openers, utensils, pots, pans, wiping cloths, sponges, and probe thermometers.

To prevent equipment to food contamination: Avoid preparing raw foods, cooked foods, and ready-to-eat foods on the same surface. For example, do not put a cooked chicken breast on the same surface the raw chicken breast was originally prepared on unless it has been washed, rinsed and sanitized

Consider using different coloured cutting boards for raw foods, cooked foods or ready-to-eat foods. For example a red cutting board could be used solely for raw meat and a green cutting board solely for cutting vegetables If cutting food items, use different knives for raw foods, cooked foods and ready-to-eat foods Properly clean, rinse and sanitize all equipment and surfaces after each task Use the correct type and amount of sanitizer

3)

People to Food Contamination

This is when people transfer harmful micro-organisms (pathogens) to a food item. Some ways people can contaminate food include: Working with unclean hands and unclean fingernails Sneezing or coughing onto their hands and not washing their hands Improperly tasting food

To prevent people to food contamination: People preparing food must have good hygiene which includes washing hands before handling food; properly covering cuts and sores on hands; not working when ill; coughing and sneezing into your arm to prevent hand contamination and wearing appropriate headgear to confine your hair Avoid touching food with hands whenever possible, using clean utensils instead of hands where possible

CHAPTER 4 Understanding Foodborne Illness

Food Handler Certification Course Study Guide

Page 43 of 162

FOODBORNE ILLNESS Foodborne illness means getting ill as a result of eating contaminated food. This is commonly known as food poisoning.

Who Can Get A Foodborne Illness? Anyone can! Health Canada estimates that between 11 – 13 million Canadians suffer from foodborne illness each year For young children, elderly people and those who have a weakened immune system (e.g. cancer or diabetes), foodborne illness can be very serious. These groups of people are more at risk of suffering from the most severe side effects of foodborne illness, which can include damage to the kidneys or reactive arthritis. In severe circumstances foodborne illness can even result in death. Symptoms are the changes in normal body function that occur when someone is ill

Incubation period means the total time between when the person eats the contaminated food and when the person starts to show symptoms

Food Handler Certification Course Study Guide

Page 44 of 162

What are the symptoms of a foodborne illness? There are different types of foodborne illness, and each type of foodborne illness have different symptoms. → The symptoms may begin immediately after eating a contaminated food → Sometimes symptoms may not begin until a few weeks after the contaminated food was eaten → For the most common types of foodborne illness, the symptoms usually begin about 12 to 48 hours after the contaminated food was eaten

Common Symptoms of a Foodborne Illness Include: fever abdominal pain cramps diarrhea nausea vomiting dehydration

chills visual disturbances sore throat difficulty swallowing muscular soreness breathing problems headache

Sometimes symptoms are so severe in people that it can result in death Food Handler Certification Course Study Guide

Page 45 of 162

Three Types of Foodborne Illness 1) 2) 3)

Foodborne Infection Foodborne Intoxication Chemical Intoxication

→ We will look more closely at the three types of foodborne illnesses

1)

Foodborne Infection

A foodborne infection occurs when someone eats food containing harmful microorganisms (pathogens). The most common type of foodborne infection involves bacteria. Harmful bacteria can come from humans and animals. Once the bacteria are eaten, it grows inside the person’s body and eventually causes symptoms to appear. The symptoms of a foodborne infection usually begin several hours to a few days after eating the contaminated food (this is also known as the incubation period). The most common incubation period for foodborne infections are 12 to 36 hours after eating the contaminated food.

1:00 p.m. Friday Contaminated food eaten

11:00 p.m. Saturday Stomach cramps, diarrhea and fever

The common symptoms of a foodborne infection are stomach cramps, diarrhea and fever. Salmonella and Campylobacter are examples of pathogens that can get into food and cause a foodborne infection if the food is eaten.

Food Handler Certification Course Study Guide

Page 46 of 162

2)

Foodborne Intoxication

A foodborne intoxication can happen two ways: a) A person eats a food contaminated with a toxin (also called a poison) that is already present in the food before it is eaten. This toxin can be produced by bacteria, moulds, or certain plants or animals. Toxins cannot be destroyed by cooking, so they have to be prevented from growing on the food before the person eats the food b) A pathogen produces a toxin inside the body after the food is eaten. For example, a bacterium can produce the toxin inside the body after it is eaten. Generally, the symptoms of a foodborne intoxication occur faster than a foodborne infection. The incubation period is typically a few minutes to a few hours after eating the contaminated food.

1:00 p.m. Friday Contaminated food eaten

4:00 p.m. Friday Vomiting

The first symptom of a foodborne intoxication is usually vomiting. Bacillus cereus, Staphylococcus aureus, and Clostridium botulinum are examples of pathogens that can produce toxins in food, or in the body, and cause a foodborne intoxication.

Food Handler Certification Course Study Guide

Page 47 of 162

3)

Chemical Intoxication

A chemical intoxication can happen two ways: a) A person eats a food contaminated with a commercially manufactured chemical. The chemical could be from a pesticide, a cleaner, or from damaged cookware and non-food grade storage containers. b) A person eats a food with a chemical additive such as MSG (monosodium glutamate) or a chemical food preservative like sulphates and nitrates. Generally, the symptoms of a chemical intoxication occur even faster than a foodborne intoxication. The incubation period is typically very short with symptoms occurring immediately to a few minutes after eating the contaminated food.

1:00 pm Friday Contaminated food eaten

1:15 pm Friday Vomiting, headache, dizziness, flushing, dry/burning throat and/or severe allergic reaction

The common symptoms of a chemical intoxication are vomiting, headache, dizziness, flushing, dry burning throat and severe allergic reactions.

Page 49 of 162

Linking Hazardous Food and Foodborne Illness The most common cause of foodborne illness in Canada is hazardous foods kept at unsafe temperatures (in the danger zone). Examples of hazardous foods kept at unsafe temperatures include: food not cooked to the proper internal temperature food not cooled quickly through the danger food not re-heated to the proper internal temperature food being left in the temperature danger zone for extended periods of time food being left to defrost at room temperature food being stored in the temperature danger zone

These foods were left in the temperature danger zone for extended periods of time

There are other causes of foodborne illness, which can include: Contamination Poor food handler hygiene Improper cleaning and sanitizing of food contact surfaces

Remember! While there are other causes for foodborne illness, the most common cause of foodborne illness is hazardous foods kept at unsafe temperatures

Food Handler Certification Course Study Guide

Page 50 of 162

What If People Became Ill At Your Food Premises? Suppose several people became ill from food prepared at your food premises. This could be costly to your business because of: → Loss of customers and sales → Lawsuits from ill people → Fines issued by the courts →Loss of reputation → Increased insurance premiums → Embarrassment → Lowered employee morale → Costs to the health care system If a food prepared at your food service business is suspected of causing a foodborne illness, you should: Call your local health department or Public Health Inspector for help Ask the customer about their symptoms, what food was eaten and when Remove any suspected food from service Save any suspected food in the refrigerator for possible testing Keep suspected food separate from other foods Label and date the container or wrapping of the suspected food Review with the staff how the food was prepared Ask staff if they were ill with similar symptoms

Food Safety Tip: Food Samples Some food service businesses, like nursing homes, are required to keep food samples from each meal prepared and served. At least 200 grams of each hazardous food served should be kept in a food grade container or wrapping for at least seven days. The samples should be labelled with the date of production and service, if different, and the name of the food (e.g. “Pork Chops Prepared and Served on November 29, 2008”)

CHAPTER REVIEW Everyone can suffer from foodborne illness, however, the elderly, very young and those with weakened immune symptoms are more at risk The three types of foodborne illness are: foodborne infection, foodborne intoxication, and chemical intoxication Symptoms for foodborne infections occur several hours to days after eating the contaminated food. The common symptoms include stomach cramps, diarrhea and fever Symptoms for foodborne intoxications occur a few minutes to a few hours after eating the contaminated food. The first symptom is usually vomiting Symptoms for chemical intoxications occur immediately to a few minutes after eating the contaminated food. The common symptoms include vomiting, headaches and dizziness The greatest cause of foodborne illness is hazardous foods kept at unsafe food temperatures

CHAPTER 5 Receiving and Storage

Food Handler Certification Course Study Guide

Page 55 of 162

RECEIVING Foods should only be purchased from government inspected food suppliers. Hazardous foods must have a permanent code marking of the manufacturer or processor designating the plant where the food was manufactured or processed. Foods with a shelf life of less than 90 days must also have the date on which the food was manufactured on or a best before date. Foods like meat and eggs must have identification stamps or tags on them to show that they are from government inspected sources.

Examples of stamps or tags that indicate hazardous foods are from government inspected sources

Receipts must be kept for one year from date of purchase so that the source of the food can be traced. During an inspection your Public Health Inspector may request to see your receipts. Examine each food item coming into your food premises for signs of spoilage, contamination, damage, dirt, insects and rodents. Check the temperature of hazardous foods Check that the delivery truck is being maintained in a manner to prevent the food from becoming contaminated Check that the delivery truck is refrigerated if necessary

→ We will discuss what to look for when receiving specific foods Food Handler Certification Course Study Guide

Page 58 of 162

Milk and Dairy Products All milk, and the majority of dairy products must be pasteurized. This means the milk has been heat treated to kill pathogens Must be delivered at an internal temperature of 4°C (40°F) or lower and well before the “best before” date Small cream and milk packages (e.g. for coffee) must also be at 4°C (40°F) when received ⌦

Unpasteurized milk is not permitted in a food premises. This means you cannot use unpasteurized milk as an ingredient nor can you sell unpasteurized milk. Ensure that you are buying from reputable suppliers

Eggs and Egg Products Eggs and egg products must be of Grade “A” or Grade “B” quality, clean, uncracked and kept refrigerated at 4°C (40°F) or lower Must be received at an internal temperature of 13°C (55°F) or lower and well before the “best before” date ⌦

Grade “C” eggs, and eggs that are ungraded, are not permitted for use in a food premises as they may not be safe for consumption

Page 59 of 162

Frozen Foods Frozen foods should not appear thawed or refrozen Frozen foods must be received at an internal temperature of -18°C (0°F) or lower ⌦

Do not accept frozen foods that have frozen liquid on the outside of the package, distorted packaging, and/or large ice crystals on the food itself

Fresh Fruits and Vegetables

Check for insects, rotting, mould and damage Fruits and vegetables should be received in clean, preferably disposable containers

⌦

Do not accept fruits or vegetables if they were shipped in containers that do not appear clean or are that are re-used disposable containers

Food Safety Tip: Bean Sprouts Bean sprouts are now considered a hazardous food and therefore must be kept refrigerated! Various sprouts, including radish, mung beans, and alfalfa, have been linked to outbreaks of Salmonella and E. coli infections in several countries. To control bacterial growth bean sprouts must be kept refrigerated.

Page 61 of 162

Vacuum Packaged Foods Vacuum packaged foods refer to foods that are put into plastic pouches and have the air removed. The package is then sealed with heat so there is no air inside. Vacuum packaging will not stop the growth of some pathogens in the food if left in the danger zone ⌦

⌦

Do not accept vacuum packaged foods that are to be delivered at the proper temperature (e.g. kept at a temperature of 4°C (40°F) or lower) but are shipped at a temperature higher than that. Measure the temperature by holding a probe thermometer between two packages (be careful not to poke any holes on the packages) Do not accept vacuum packaged foods if the packages have any holes, tears, bubbles, slime or discolouration on the food

Modified Atmosphere Packaged (MAP) Foods Modified Atmosphere Packaged (MAP) foods refer to foods that are put into plastic pouches, have the air removed and replaced with a nitrogen-carbon dioxide gas mixture before sealing the pouch with heat. MAP packaging will not stop the growth of some pathogens in the food if left in the danger zone ⌦

⌦

Do not accept MAP foods that are to be delivered at the proper temperature (e.g. kept at a temperature of 4°C (40°F) or lower) but are shipped at a temperature higher than that. Measure the temperature by holding a probe thermometer between two packages (be careful not to poke a hole in the packages) Do not accept MAP foods if the packages have any holes, tears, bubbles, slime or discolouration on the food

Water and Ice Water must be potable. Potable means safe to drink. If you rely on a private well for your water supply ensure that it is regularly tested and free of any bacteria Ice must be made from potable water Check bottled water for proper seals that are undamaged

⌦ Do not accept bottled water if the seals on the caps are damaged/missing ⌦ Do not accept bagged ice if the bag is torn and the ice is exposed to the air

BEST BEFORE DATES Best before dates are required by law on all foods with a shelf life less than 90 days, with a few exceptions (such as fresh fruit and vegetables). The best before date is the period of time during which an unopened food stored under proper conditions will retain its wholesomeness and nutritional value. Foods may still be safe to eat after this date but the food may lose some of its nutritional value (e.g. Vitamin C content). The food may also lose some of its flavour or its texture may change. Examples of foods with “Best Before” dates include eggs, yogurt and milk. Do not accept food past the best before date Food Handler Certification Course Study Guide

Page 63 of 162

EXPIRY DATES

An expiry date is similar to a best before date, except it is used on fortified foods (foods that have vitamins or minerals added to it) with a short shelf life. Foods should not be eaten after this date. Examples of foods with “Expiry” dates include baby formulas and nutritional supplements

Do not accept food past the expiry date

What are the other numbers on cans? The other numbers on cans are codes used by the manufacturer (e.g. packaging numbers). There is no standardized system for these codes, and they are all specific to the manufacturer. Check with the manufacturer if you have a concern about the other numbers on the can

STORAGE Food Containers Food containers must be of good quality and be commercial food grade Re-useable food containers must be easy to clean and sanitize Cardboard can be used as an original container for certain foods such as fruits and vegetables. Cardboard cannot be reused to store any foods

⌦ ⌦

Do not use plastic tubs or pails for food storage that originally contained cleaning products Do not store food in the original metal can after it has been opened. Remove the food from the can and put it in a proper food grade container. For instance after opening a can of ketchup transfer the remaining contents into a stainless steel or food grade plastic container and dispose of the can

Safe Food Storage Practice the FIFO (First In First Out) method of stock rotation Throw away any food past the “Best Before” or “Expiry” date Cover foods in clean, food-safe wrappers or containers with lids Label foods that have no label Keep food storage areas clean at all times, sweep up any dirt/fallen debris, and do not overload shelves or store food on the floor Food Handler Certification Course Study Guide

Why do foods have to be stored 15 cm (6 inches) off of the floor? it is the law makes it easier to clean the floor helps keep food dry makes it easier to see if there is insect and/or rodent activity

Food must be stored at least 15 cm (6 inches) off of the floor

Dry Storage Many non-hazardous foods can be stored safely in dry storage. This includes flour, sugar, spices, bread crumbs, unopened canned foods, cereal, uncooked rice, and uncooked pasta The best temperature range for dry storage is 15°C to 22°C (59°F to 71°F). All foods must be stored at least 15 cm (6 inches) off of the floor Foods in dry storage should also be stored in the original, unopened container or in a clean, covered and labelled container to prevent potential contamination

What will freezing raw fish at -20°C (-4°F) for 7 days or -35°C (-31°F) for 15 hours do to any parasite? Freezing kills parasites. Keeping raw fish at these temperatures will kill any parasites in the fish. This is important when the fish is to be consumed raw, like for sushi. Does freezing kill bacteria? No! Freezing stops the growth of bacteria, but the bacteria are still alive. Only cooking will kill bacteria.

Chemical (Cleaning Supply) Storage Store cleaning supplies separately and away from food and food contact surfaces Store cleaning supplies in their original labelled containers, and keep them tightly closed Clean up any spills as soon as possible Wash hands before and after handling chemicals

Cleaning chemicals should be stored separately and away from food

Page 71 of 162

PREPARATION Thawing/Defrosting The acceptable ways to thaw or defrost hazardous foods are by using one of the following methods:

Microwave

Refrigerator

Cold Running Water

When defrosting a hazardous food by microwave or cold running water, it should be immediately cooked Defrosting a hazardous food by refrigerator is the safest method, although it takes the longest

Food Safety Tip: Defrosting Properly Never thaw or defrost a hazardous food by leaving it out on the counter. The surface of the food will be in the danger zone while the inside of the food may still be frozen and as a result, pathogens will start to grow on the surface of the food

This food is being defrosted in the walk-in fridge

Handling Produce Fresh fruits and vegetables are an important part of a healthy diet, but they can also be a cause of foodborne illness. In Canada, fresh produce is a big source of foodborne illness if not handled and prepared properly.

Food Safety Tips: Handling Fresh Produce At the grocery store, bag fresh fruits and vegetables to protect them from pathogens that might be on the grocery cart, your hands or juices that might drip from raw meat, poultry and fish Pathogens grow faster and are more likely to survive on pre-cut fresh produce. Keep pre-cut fresh produce refrigerated and use it by the best before date Wash your hands when handling and preparing fresh produce, and make sure to clean and sanitize utensils and cutting surfaces before you start and after you finish. Use separate cutting surfaces where possible Carefully rinse all fresh produce under running water just before preparing or eating. Do not use soap or sanitizer on the produce. Scrub firm produce (e.g. cantaloupes, melons) with a clean brush. Discard damaged outer leaves of vegetables and soak leafy greens and dense vegetables such as broccoli and cauliflower in water for a few minutes to dislodge dirt, then rinse under clean running water

COOKING Cook hazardous foods completely in one continuous process Cook to the required minimum internal temperature Use a probe thermometer to check the final internal temperature after cooking

⌦ ⌦

Do not cook hazardous foods too far in advance of service. The safest thing to do is to immediately serve food after cooking Do not “slow cook” hazardous foods (low temperature for a long time period)

SERVICE Hot Holding For Service (e.g. Buffets) Hazardous foods being held for service after cooking must be kept at an internal temperature of 60°C (140°F) or hotter at all times Acceptable hot holding equipment includes steam tables, double boilers, sterno candles, heated cabinets and chafing dishes The hot holding equipment must be preheated before using. For example, if using a steam table turn the table on and fill with water prior to placing any food in the unit. Ensure that the steam table is producing enough steam to keep food at 60 °C (140°F) or hotter prior to putting any food in the unit. This could take more than an hour depending on the unit Food must have an internal temperature of 60°C (140°F) or hotter before being placed in the hot holding equipment Hot hold small batches of food to help maintain the proper temperature Protect food from contamination and help keep the heat in by using lids, covers or shields Periodically check the internal temperatures of the food in hot holding with a probe thermometer to ensure it is at 60°C (140°F) or hotter

Food Safety Tip: Hot Holding Hot holding equipment is not to be used for cooking or reheating hazardous food. Some equipment may take longer than two hours to reheat the food, and some equipment may not have the ability to get the food reheated to the proper temperature. Food must always be reheated to the proper temperature before placing it in the hot holding unit

Cold Holding for Service (e.g. Salad Bars) Hazardous foods being held for service that should be cold must be kept at an internal temperature of 4°C (40°F) or colder at all times Acceptable cold holding equipment includes refrigerators, salad bars (as seen in picture), display coolers, and stainless steel pans in ice baths If ice is used, the melted water should drain away from the food. Frozen ice packs can also be used to keep food cold Food must have an internal temperature of 4°C (40°F) or colder before being placed in the cold holding equipment Cold hold small batches of food to help maintain the proper temperature Protect food from contamination, and help maintain the temperature by using lids, covers or shields Periodically check the internal temperatures of the food in hot holding with a probe thermometer to ensure it is at 4°C (40°F) or colder

Food Safety Tip: Cold Holding Some equipment may take longer than two hours to cool hazardous foods to 4°C (40°F) or colder, and some equipment may not have the ability to get the foods to an internal temperature of 4°C (40°F) or colder. As a result, hazardous foods being kept cold should have an internal temperature of 4°C (40°F) or colder before placing it in the cold holding unit

Remember! Make sure HOT FOOD IS KEPT HOT at 60°C or hotter Make sure COLD FOOD IS KEPT COLD at 4°C or colder

Food Handler Certification Course Study Guide

Page 77 of 162

COOLING FOODS The goal is to cool hazardous foods as quickly as possible through the Danger Zone (4°C - 60°C) as improperly cooling foods can cause foodborne illness. Hazardous foods must be cooled as fast as possible to an internal temperature of 4°C (40°F) or colder.

Did you know? A large container, 40 cm (16-inch pot) of hot food (e.g. beef stew) placed directly into the refrigerator after cooking can take more than 6 days to cool to 4°C (40°F)!

Cooling Hazardous Foods Faster Containers Aluminum and stainless steel containers cool food the fastest. Glass and plastic are poor containers to use as they insulate heat The shallower the container, the faster the food will cool Use a 5 cm (2 inch) deep pan for heavy thick liquids like chilli or for dense foods like beans or rice Use a 7.5 cm (3 inch) deep pan for thin liquids such as soup or gravy These foods are cooled in stainless steel containers and in the walk-in fridge

Quantity Reduce larger quantities of heated foods to smaller quantities Cut large pieces of meat into smaller pieces, then refrigerate or freeze

Stirring Stirring helps cool food faster Speed up cooling by occasionally stirring the food while it is chilling. This can be as simple as stirring the food every 15 to 30 minutes

Food Handler Certification Course Study Guide

Page 78 of 162

Ice bath Use a sink or container large enough to hold the pot of hot food and place the pot of food in the ice so that the pot is surrounded by ice The outside of the bottom and sides of the pan containing the food should be touching the ice Stir the food periodically while in the ice bath to release heat from the middle. After the food has cooled place it into the refrigerator

Air circulation in the refrigerator and freezer Let foods chill uncovered for 30-45 minutes in the fridge or freezer, then cover them with a proper cover Do not “stack” containers as it will block air circulation Wired shelves help the air circulate in the refrigerator Do not place containers in front of the fan in the refrigerator Always close the door to the refrigerator when not in use. Remember that the warmest part of the refrigerator is usually by the door

Blast Chiller Some food premises may have a blast chiller, which acts like an oven with the exception the foods are chilled as opposed to heated up Do not “stack” containers as it will block air circulation Make sure the machine is kept clean and sanitary at all times

Remember! Use aluminum or stainless steel shallow pans Split up large quantities of food into smaller batches Uncover and stir occasionally Use an ice bath, and replace ice when it melts Place the food in the refrigerator or freezer after using an ice bath Cover, date and label the container when the food is cooled to an internal temperature of 4°C (40°F) After cooling, store cooked and ready-to-eat foods above raw foods in the refrigerator or freezer

REHEATING FOODS The goal is to reheat hazardous foods as quickly as possible through the Danger Zone (4°C - 60°C) as improperly reheating foods can cause foodborne illness. Hazardous foods must be reheated as fast as possible to an internal temperature equal to the original cooking temperature or 74°C (165°F) within 2 hours. The original cooking temperatures for hazardous foods were mentioned earlier on pg. 75.

Reheating Hazardous Foods Faster Stir or portion food into smaller amounts to help reheat faster Use a method that will re-heat the food quickly, like a stove, oven or microwave ⌦

Do not use hot holding equipment, such as a steam table, to reheat or to cook food. Hot holding equipment is not designed to reheat or cook food as it may take longer than two hours and/or the temperature may not get to the original cooking temperature or 74°C (165°F)

Do not use hot holding equipment to reheat hazardous foods

Food Safety Tip: Leftovers The best strategy is not to have any leftovers. If you do have leftovers, cool it quickly to an internal temperature of 4°C (40°F) or lower. You can reheat it to the original cooking temperature once. After that, the food must be thrown away. Also remember not to mix leftovers with freshly made food!

Remember! Reheat hazardous foods to its original cooking temperature or 74°C (165°F) within 2 hours

Food Handler Certification Course Study Guide

MICROWAVES Using microwaves make preparing foods fast and easy, but you have to be aware of certain things when you use them. When cooking or reheating in a microwave: Arrange food items uniformly in a covered dish. Cover foods with a microwave-safe material to hold in moisture and provide even heating Debone large pieces of meat or cook large pieces of meat on medium power (50%) for longer times Stir or rotate food once or twice during microwaving, and make sure you cook it to the proper internal cooking temperature using a probe thermometer Reheat leftovers to 74°C (165°F) or the original internal cooking temperature within 2 hours. Stirring the food will help it achieve the proper temperature ⌦ Do not microwave whole, stuffed poultry ⌦ Avoid partially cooking food. Always thoroughly cook food in the microwave or finish it off on the grill, barbeque, stove or in the oven immediately after ⌦ Due to the possibility of uneven heating, microwaving baby food and baby formula is not recommended. If you must microwave baby food and formula, stir the food, shake the bottles and take a temperature check before serving to an infant or child

Remember! Microwave ovens apply heat unevenly to foods, so use a probe thermometer in different spots to verify that all parts of the food have been thoroughly cooked to the proper internal cooking temperature Food Safety Tips: Using Microwaves Use only containers and wraps labelled as “microwave oven safe” in the microwave. This marking should be on either on the packaging or on the container itself. Do not use containers such as margarine tubs or plastic bags in the microwave, as these can melt in the food, possibly causing chemicals from the container or bag to get into the food. As well, avoid using dishes with metallic rims or cookware with metal parts, brown bags and newspapers in the microwave

GOOD SERVICE PRACTICES Part of handling food safely involves good service practices. If good service practices are applied and maintained, it results in good customer service, and the benefit of good customer service is repeat business. Practice good personal hygiene Use properly cleaned and sanitized tongs and utensils when preparing and serving food Hold plates by the bottom or edges Hold cups or glasses near the bottom or by the stem Hold utensils such as forks, knives and spoons by the handles Scoop ice with a long-handled, non-breakable scoop or tongs Dispensing scoops and dippers for ice cream must be kept in a dipper-well with running water between servings Table surfaces and serving trays should be wiped using a clean cloth with sanitizing solution between each use Leftover, unwrapped or prepared foods that have already been served to customers, including breads, rolls and sauces must be thrown away Single service items such as disposable cups and plastic utensils should be stored off the floor in closed containers and cannot be reused Clean and sanitize food utensil dispensers and other dispensers regularly

Do not touch any part of a glass, utensil or plate that will touch food or a person’s mouth

⌦ Avoid touching food with your hands. Use a utensil where possible ⌦ Do not touch any part of a glass, dish, plate or utensil that may also touch a person's mouth ⌦ Do not stack cups. Hold them by the handle, on saucers or use a tray Food Handler Certification Course Study Guide

Page 82 of 162

SELF-SERVICE AREAS Self-service areas include salad bars, buffets and bulk food containers in food stores. All foods must be protected from contamination Self-service lines such as salad bars and buffets need to have food shields (e.g. pan cover) or “sneeze guards” installed at appropriate heights Containers with hinged lids may be used for bulk foods Clean utensils and plates should be available for customers at all times Each food needs its own serving utensil Serving utensils should be placed in the food so that the handles are pointing out Eating utensils should be displayed so that the handles are pointing out of the food Use a sanitized probe thermometer to check the internal temperatures of hazardous foods on the buffet line and at the salad bar

Store all serving utensils, glasses, utensils and plates for customers properly

⌦ Customers must not be allowed to return to a salad bar or buffet with used plates or utensils.

Remember! Keep hot foods hot and cold foods cold in self-service areas. Hazardous foods should be kept at 4°C (40°F) or colder or 60°C (140°F) or hotter Food Handler Certification Course Study Guide

CHAPTER 7 HACCP (Hazard Analysis Critical Control Points)

Food Handler Certification Course Study Guide

Page 87 of 162

HAZARD ANALYSIS CRITICAL CONTROL POINTS (HACCP) HACCP is pronounced “haa-sip.” HACCP stands for:

Hazard Analysis Critical Control Points HACCP is a food safety inspection system that reviews all food handling processes in a food business from receiving to service to the customer. It is also called an “audit”. What is the purpose of HACCP? identify poor food handling processes correct these poor processes

What is the goal of HACCP? prevent foodborne illness and make the safest food possible

The Flow of Food HACCP requires that food be observed at each step it goes through at a food premises, from the start (e.g. receiving) to the end (e.g. service to the customer). This is known as the flow of food.

Food Handler Certification Course Study Guide

Page 88 of 162

What are Common Steps in the Flow of Food? Receiving or delivery from the supplier Storage Thawing Preparation Cooking/Reheating Holding Cooling Service or delivery to the customer

HACCP Flow Chart A HACCP flow chart is a diagram showing the flow of food and what happens to each ingredient in the food item from start to finish. The HACCP flow chart shows: Safe food handling techniques to be followed in each step in the flow of food What a food handler should do if a safe food handling technique is not met. This is also called a corrective action. For instance, if a chef checks the internal temperature of a food and finds it is not at the minimum internal temperature the corrective action would be to put the food back in the oven and continue cooking it until it has reached the minimum internal temperature What records need to be kept (e.g. final cooking temperature logs; meat and poultry receipts)

Example of a Simple HACCP flow chart for Roast Chicken (a more detailed flow chart is on pg. 93)

Food Handler Certification Course Study Guide

Page 89 of 162

Critical Control Points (CCP) HACCP also identifies Critical Control Points (CCP) during the preparation of a hazardous food. Critical Control Points (CCP) are points during food preparation where proper food handling techniques can reduce or eliminate pathogens or other contaminants. Some examples of Critical Control Points include: Final internal cooking temperature Final internal reheating temperature Final cooling temperature Hot and cold holding temperatures Handwashing Cleaning and sanitizing

Remember! The Hazard Analysis Critical Control Points system does the following: Monitors the flow of food from start (ex receiving) to finish (e.g. service to customer) by breaking a recipe or food handling process into steps by using a HACCP flow chart Identifies Critical Control Points in the preparation of the food Sets food safety standards and corrective actions for each step in the recipe or process

Developing a HACCP Plan The HACCP system is a seven step system. The seven steps are: 1. Assessing food safety hazards 2. Identifying Critical Control Points 3. Establishing Standard Operating Procedures 4. Monitoring Critical Control Points 5. Taking Corrective Action 6. Setting up an effective record-keeping system 7. Verifying your system is working

Food Handler Certification Course Study Guide

Page 90 of 162

Step 1: ASSESSING FOOD SAFETY STANDARDS The question to ask at this step is: Where are food safety problems most likely to occur? Identify menu items that contain hazardous foods. It is easier if you concentrate on one menu item at a time Draw a flow chart for that menu item. A flow chart is a picture of what happens to the ingredients in a food item from start to finish Identify food safety concerns (hazards) that could develop in your recipe ingredients during each part of the flow of food

Step 2: IDENTIFYING CRITICAL CONTROL POINTS (CCP) The question to ask at this step is: Can a food handler control or eliminate the food safety problem? If you can answer “yes” to this question, then it is a CCP A CCP must be something you can measure or observe. An example would be a final internal cooking temperature or observing handwashing CCPs usually involve cooking time and temperature, food handler health and hygiene, cross-contamination, cleaning and sanitizing

Step 3: ESTABLISHING STANDARD OPERATING PROCEDURES These are the requirements that must be met to keep food safe at each step in the flow of food Standard Operating Procedures should be as specific as possible and must be based on safe food handling techniques and laws A Standard Operating Procedure is something that you can measure or observe. An example would be cooking temperatures and times, or cleaning and sanitizing of food preparation work surfaces and equipment.

Step 4: MONITORING CRITICAL CONTROL POINTS (CCP) The questions to ask at this step are (using beef stew as an example): What food will be monitored? Beef stew How will the food be monitored? With a clean and sanitized probe thermometer Who will monitor it? The chef What temperatures need to be recorded and when? Cooking, reheating, and holding temperatures and the time the temperatures were taken need to be recorded on a temperature log sheet How often will it be monitored? Every ½ hour while the food is in the steam table Food Handler Certification Course Study Guide

Page 91 of 162

Step 5: TAKING CORRECTIVE ACTION The question to ask at this step is: What should a food handler do if the CCP is not meeting the standard operating procedure? A corrective action must be established for each CCP and standard operating procedure Examples of corrective actions include: Rejecting a shipment Calling a supervisor or manager for advice Cooking the food longer or at higher temperatures Moving or covering the food to prevent cross-contamination Discarding the food Washing the hands at critical times Sanitizing work surfaces and utensils at critical stages in food preparation Step 6: SETTING UP AN EFFECTIVE RECORD KEEPING SYSTEM The question to ask at this step is: What records are needed to show that food is being prepared safely? Records should show that CCPs and standard operating procedures are being monitored Receipts of where the food came from should also be kept Keep written records simple, within reach and easy to use Examples of what you can do: Develop a HACCP recipe binder Include the CCP, standard operating procedures, required monitoring and temperature recording as well as corrective actions for each menu item Use charts for recording: Refrigerator temperatures at specific times Final cooking temperatures and time Hot or cold holding temperatures and time Cooling temperature and time Reheating temperature and time Step 7: VERIFY THAT THE FOOD SAFETY SYSTEM IS WORKING The questions to ask in this step about the HACCP system in place are: Is it working for the food premises? Is it helping to identify, prevent and correct problems with food handling? Is it helping with employee training? Does anything need to be changed? It may help to review your records, review public health inspection reports and listen to employee concerns when deciding what needs to be changed Food Handler Certification Course Study Guide

Creating a HACCP Flow Chart for Roast Chicken Step in Flow of Food Receiving

Standard Operating Procedures and Corrective Actions - make sure chicken is frozen solid and has an internal temperature of -18°C (0°F) or lower - check for government inspected tag or stamp, obtain a receipt - if there is a problem, tell the supervisor or do not accept the delivery

Storage

- keep freezer at -18°C (0°F) or lower - record the temperature of the refrigerator and freezer once each shift - if there is a problem, tell the supervisor

Thawing

- thaw safely using one of these methods: -refrigerator at 4°C (40°F) or lower on bottom shelf -under cold running water -microwave - if there is a problem, tell the supervisor

Preparation

- wash hands before and after handling raw chicken - clean and sanitize work surfaces, utensils and wiping cloths after working with raw chicken - minimize time the raw chicken is kept in the temperature danger zone - if there is a problem, tell the supervisor

Cooking

- make sure the internal temperature of chicken gets to 82°C (180°F) or higher for at least 15 sec. - measure with a sanitized probe thermometer - if the temperature is below 82°C (180°F), continue to cook the chicken - if possible, record final cooking temperature of three chickens from each batch - if there is a problem, tell the supervisor

Cooling

- cut whole chicken into small pieces with sanitized utensils - place in shallow pans and use an ice bath if possible - quickly cool chicken to an internal temperature of 4°C (40°F) by placing it in the refrigerator or freezer as soon as possible - record internal food temperature and time every hour until 4°C (40°F) is achieved - if there is a problem, tell the supervisor

Reheating

- reheat cooked chicken quickly to 74°C (180°F) or higher - measure internal temperature with a sanitized probe thermometer - record the temperature of the chicken - if there is a problem, tell the supervisor

Hold for Service

- hot hold chicken at an internal temperature of 60°C or higher - measure with a sanitized probe thermometer - record the temperature of the food and the time every ½ hr - if there is a problem, tell the supervisor

HACCP Inspection or “Food Safety Audit” Public Health Inspectors may conduct a HACCP inspection when inspecting a food premises. This would also be known as a “food safety audit” or a “HACCP audit.” During the HACCP audit, the Public Health Inspector will devote much of the audit to observing the food being prepared. In particular, the Public Health Inspector will observe the Critical Control Points (CCP), as they can reduce the likeliness of foodborne illness occurring.

The Public Health Inspector will then be able to suggest ideas or corrective actions and help focus in on areas where improvement in the food preparation process to prevent contamination, bacteria growth and food poisoning can occur.

Remember! The HACCP inspection will help confirm that foods being prepared are the safest and highest quality possible

CHAPTER 8 Handwashing and Personal Hygiene

Food Handler Certification Course Study Guide

Page 97 of 162

HANDWASHING Handwashing Sinks Hands should always be washed at the dedicated handwashing sink. All food premises are required by law to have a dedicated handwashing sink in each food preparation area. The handwashing sink is only for handwashing; do not block the handwashing sink and do not put dishes or other items in this sink.

Why is a dedicated sink required for the sole use of hand washing? It is the law under the Food Premises Regulation It prevents contamination of food and utensils. Do not wash your hands where dishes, pots, utensils or foods are being washed It encourages people to wash their hands

Supplies at Handwashing Sinks Liquid Soap in a dispenser

Paper towels, a cloth towel roller or a hot air dryer

Hot and cold running water

Waste container

Food Handler Certification Course Study Guide

Page 98 of 162

Correct Handwashing Procedure

Use warm, running water Use liquid soap. Bars of soap are not permitted in food premises Lather for at least 20 seconds, scrubbing all parts of the hands including inbetween fingers, under fingernails, the back of the hands and the wrists If you are wearing a ring or jewellery, ensure that you thoroughly clean under and around them Hot air driers and cloth towel rollers also permitted for use. If a single cloth towel is used, it must be clean and used only once – a new cloth towel is required for each time the hands are washed Food Handler Certification Course Study Guide

Page 99 of 162

PERSONAL HYGIENE Everyone, including healthy people, have micro-organisms on their hands and their body. These micro-organisms can be either helpful to your body or harmful (otherwise known as pathogens). It is important to remember that you can not see micro-organisms with just your eyes, and pathogens can get into food and make people sick. By practising proper personal hygiene you can help prevent foodborne illness!

Good Hygiene Food handlers who are sick should NOT work with food! The pathogens that have made you sick can easily be spread to other people through food and/or utensils. Report any illnesses to a supervisor or manager. If you are sick do not return to work until you have been symptom free for at least 24 hours. This is especially important if the symptoms include: diarrhea vomiting a severe cold with coughing and sneezing What if you have a cut on your hand? You can still work, provided you: Keep the cut clean to prevent infection Wear a clean bandage over the cut Wear a glove over the bandaged hand. The glove helps to keep the cut clean and prevents the bandage from getting into any food Follow proper procedures for glove use

Food Handler Certification Course Study Guide

Page 100 of 162

Proper Glove Use Food handlers in Ontario are not required under the Food Premises Regulation to wear gloves when handling food, unless they have a cut or open sore on their hands or fingers. When using gloves, the keep in mind the following tips: glove use does not replace proper handwashing wear gloves that fit properly gloves must be worn if food handlers have a cut or open sores on their hands change gloves when switching between different foods, especially when switching from a raw food to a ready-to-eat food practice proper handwashing and change your gloves after using cleaning chemicals always properly wash your hands before putting gloves on always properly wash your hands after removing gloves always properly wash your hands between glove changes avoid using latex gloves where possible, as people can be allergic to latex

Remember! Wearing gloves does not replace proper handwashing

Alcohol-Based Hand Sanitizers (Gels) Alcohol-based hand sanitizers may be used, but only after properly washing your hands with soap and water.

Remember! Alcohol-based hand sanitizers do not replace proper handwashing Food Handler Certification Course Study Guide

Page 101 of 162

Personal Cleanliness Bathe or shower every day Keep fingernails clean and trimmed Do not use nail polish Do not wear excessive jewellery Wash hands after tissue use Keep uniforms and aprons clean Keep hair clean and confined Frequently wash hands

What habits should food handlers avoid? coughing near food picking or scratching skin near food smoking inside a food premises putting fingers in mouth, nose, hair sneezing near food chewing gum while working with food

Food Handler Certification Course Study Guide

Page 102 of 162

Apron Use Food handlers should put on a clean apron each shift Food handlers should change aprons as they become dirty Aprons may need to be changed more than once a day! Aprons are not hand towels

Tobacco Use According to the Smoke-Free Ontario Act and the Food Premises Regulation, it is against the law to use tobacco in a public place or workplace. Contamination may occur from ashes or butts. Hands may also become contaminated with saliva when smoking, which in turn can cause people-to-food contamination.

Remember! Hands must be properly washed afterwards if tobacco is used

Food Handler Certification Course Study Guide

Page 103 of 162

CHAPTER REVIEW A dedicated handwashing sink in each food preparation area is required because: it is the law, it prevents contamination of food and utensils, and it encourages food handlers to wash their hands Follow the correct handwashing procedure when washing hands Food handlers who are sick are not allowed to work with food Wearing gloves does not replace proper handwashing Alcohol-based hand sanitizers do not replace hand washing Practice good hygiene and personal cleanliness when working with food Tobacco usage is not allowed in food premises Notes:

CHAPTER 9 Food Allergies: A Matter of Life or Death

Food Handler Certification Course Study Guide

Page 107 of 162

FOOD ALLERGIES A food allergy involves an immune system reaction in the body. In Canada, approximately 3-4% of adults and up to 6% of young children has a form of food allergies. Often, there are no cures for a person who has a food allergy. People who are allergic to certain foods must avoid those foods in order to prevent serious health consequences. Why Should Food Handlers Care About Food Allergies? The health of the customer is at risk Customers with food allergies will ask questions about ingredients and you need to be prepared to answer these questions Accurate and timely ingredient information may be a matter of life and death

Most Common Foods That Cause Food Allergies Peanuts Tree nuts (almonds, Brazil nuts, cashews, hazelnuts (filberts), macadamia nuts, pecans, pine nuts, pistachio nuts and walnuts) Shellfish Milk Eggs Fish Soy Sesame seeds Wheat

Food Handler Certification Course Study Guide

Page 108 of 162

Common Symptoms of Allergic Reactions Gastrointestinal symptoms - nausea - vomiting - diarrhea

Respiratory symptoms - runny nose - asthma (wheezing)

Skin symptoms - hives - eczema - swelling of eyelids, lips, hands or feet

Other symptoms - tightening of the throat - headache - anaphylaxis

Anaphylaxis Anaphylaxis (pronounced “anna-fill-axis”) is a life threatening allergic reaction. It affects less than 1-2% of the population in Canada. The symptoms associated with anaphylaxis includes swelling, difficulty breathing, abdominal cramps, vomiting, diarrhea, suffocation, coma and even death. Anaphylactic shock is a serious form of anaphylaxis that can occur rapidly. The first symptoms of anaphylactic shock may be a feeling of uneasiness, red face and feeling of warmth. Light-headedness, coughing, sneezing, and shortness of breath may occur, followed by shock where blood pressure falls, suffocation can occur and the person becomes cold, clammy and faint. If a customer tells you they are having anaphylactic shock, you should immediately call “911” and request for medical help.

What is an epinephrine auto-injector? Due to the severity of anaphylactic shock, people who have severe food allergies may carry an epinephrine auto-injector (ex. “EpiPen”) which contains epinephrine, a substance that helps to prevent shock. The symptoms may temporarily go away, but further medical treatment is still necessary Food Handler Certification Course Study Guide

Page 109 of 162

How much of the food does a person need to be exposed to for an allergic reaction to occur? Allergic reactions can be triggered by very small or trace amounts of the food. One bite of the tiniest portion of the food can be fatal. As well, a contaminated utensil that was exposed to the food but not properly cleaned and sanitized can trigger a life threatening allergic reaction.

How can food handlers help customers with food allergies? People with food allergies must carefully avoid those food ingredients that cause their allergic reaction. Therefore, it is very important to provide your customers with accurate ingredient information. Never guess the ingredients that are in a food!

Remember! Allergic reactions to food, particularly anaphylaxis, can be life threatening to some people and even cause death. If a customer tells you they are having anaphylaxis, you should immediately call “911” and request for medical help

FOOD INTOLERANCE Food intolerance is different than a food allergy in that a food tolerance is not an immune system reaction. Food intolerances normally occur because the body is unable to digest or absorb certain foods. As well, a food intolerance usually occurs if a normal-sized portion of the food is eaten, unlike a food allergy where even a small amount of the food can cause a reaction. The symptoms of a food intolerance varies from person to person, but usually involves the gastrointestinal system, including bloating, loose stools, gas or diarrhea. An example of a food intolerance is celiac disease. Symptoms like abdominal pain, flatulence and diarrhea can occur after a person eats a food containing cereal grains containing “gluten” (ex. wheat, barley, rye). Food Handler Certification Course Study Guide

Page 110 of 162

Another example of a food intolerance is lactose intolerance. Symptoms like abdominal pain, bloating, diarrhea and flatulence can occur after a person eats a food containing lactose (ex. milk, cheese, dairy products).

LABELS ON FOOD PACKAGES Canadian laws require that most pre-packaged foods include a list of ingredients on the label in descending order of quantity in the food. These food labelling requirements help people with allergic reactions to avoid the problem foods.

Example of a food label

Currently, food premises such as restaurants, fast food outlets and bakeries are not required by law to have these labelling requirements. These food premises can, however, help by providing customers with accurate information when a customer asks about the ingredients in a food being sold or served at the restaurant. Some restaurants put a message on their menus stating: “Ingredient inquiries are welcome, please ask your server.” Did you know? Not all ingredients may be listed on a label as some are exempt (ex. spices/seasonings, flour). As a result, sometimes a common food allergen may go undeclared or is not listed on a label. In the case that an ingredient that is supposed to be listed is not listed, a “food recall” may take place

PROTECT YOUR CUSTOMERS, YOUR BUSINESS AND YOURSELF! Establish a food ingredient information policy The policy will be not only for staff, but also for customers. The policy should state who can answer questions involving ingredients or where the information can be found. In most cases, the chef may be the best person to give this type of information. Communicate with staff List food ingredients with each menu item or have a recipe binder on hand. Make sure the entire staff is aware of this information. Find out if in doubt! Never guess about the ingredients of a food. Find out what the ingredients are and tell the customer. If you do not know, say so. Treat any customer concern about food ingredients seriously Ingredient inquiries by customers must be taken seriously. Concerns about food ingredients are not just a “like” or “dislike” issue but a life or death issue that must be taken seriously. Tips during food preparation to reduce potential allergic reactions wash hands before preparing and handling food clean and sanitize work and cutting surfaces, utensils and any equipment that food touches use separate cooking equipment and utensils when preparing food for anyone with a food allergy store common foods associated with allergies separately label all food products and ingredients Post “Emergency Procedures” where everyone can see them Create an “emergency procedures” list so if a person suffers an allergic reaction (or any other medical emergency), directions on how to handle it will be provided (ex. call “9-1-1” and request for medical help).

CHAPTER REVIEW A food allergy involves an immune system reaction in the body Anaphylaxis is a life threatening allergic reaction. Anaphylactic shock is a serious form of anaphylaxis that can severely lower blood pressure and cause fainting and suffocation The best method for prevention of allergic reactions for people who have food allergies is for them to avoid the foods they are allergic to A food intolerance does not involve an immune system reaction; it occurs when the body is not able to digest or absorb certain foods Food labels help determine what ingredient is in a food item Accurate ingredient information for a food should always be provided to customers upon request Notes:

CHAPTER 10 Proper Cleaning and Sanitizing

Food Handler Certification Course Study Guide

Page 115 of 162

PROPER CLEANING AND SANITIZING Clean and sanitize utensils, equipment or surfaces after each use Clean and sanitize when switching from one food item to another. For example, when switching from preparing raw chicken to cooked chicken on the same cutting board Clean and sanitize at least once a day for grill surfaces and griddles Clean and sanitize at least every two hours for equipment in constant use with the same food. For example, a deli meat slicer

Remember! Any utensil, equipment or surface will first have to be cleaned properly in order for it to be effectively sanitized afterwards

Cleaning Schedule A cleaning schedule should be created and followed to help ensure that a food premises keeps clean and organized. A cleaning schedule should include the following information: What is to be cleaned and sanitized When it is to be cleaned and sanitized Who is responsible to clean and sanitize the item What chemicals to use and how to mix them How to clean and sanitize the item

Example of a Cleaning Schedule

Food Handler Certification Course Study Guide

Page 116 of 162

WASHING DISHES, UTENSILS AND EQUIPMENT Proper washing of dishes, utensils and equipment involves cleaning, rinsing and sanitizing.

Cleaning Cleaning means to remove food residue, stains, grease and other dirt Warm water and soap/detergent are used in cleaning

Rinsing Rinsing means to remove the soap and loosened dirt after cleaning Clean, warm water (at least 43°C) is used in rinsing

Sanitizing Sanitizing means further reducing the number of pathogens to safe levels after cleaning and rinsing Sanitizing can be done in two ways: either by heat or by using chemicals

Food Handler Certification Course Study Guide

Page 117 of 162

Two Types of Sanitizing 1) HEAT SANITIZING This method sanitizes dishes, utensils and equipment by using very hot water, usually much hotter than what you can get at a regular sink. If you use heat sanitizing when manually washing, the temperature of the water must be at a minimum of 77°C (171°F) or higher and be in contact with the dish, utensil or equipment for at least 10 seconds. If you use heat sanitizing when using a machine dishwasher, the temperature of the water during the sanitizing cycle must be at a minimum of 82°C (180°F) or higher and be in contact with the dish, utensil or equipment for at least 10 seconds. 2) CHEMICAL SANITIZING This method sanitizes dishes, utensils and equipment by using a solution of a mixture of water and chemicals. There are three acceptable sanitizers solutions for use in a food premises (“ppm” means “parts per million”): Chlorine solution (sodium hypochlorite or “bleach”) at 100 ppm Quaternary ammonium solution (“quats”) at 200 ppm Iodine solution at 25 ppm The temperatures for all these solutions must be at a minimum of 24°C (75°F) or higher and be in contact with the dish, utensil or equipment for at least 45 seconds. Never mix a chemical sanitizer solution with other chemicals solutions, like soaps or other cleaners.

Is Vinegar an approved chemical sanitizer solution? No! Vinegar can be used to help remove grease from surfaces or for general cleaning, but it is not recognized as an approved chemical sanitizer solution

Food Handler Certification Course Study Guide

Page 118 of 162

Sanitizer Test Strips Sanitizer test strips or a sanitizer test reagents must be available to measure the concentration (the “ppm”) of the chemical sanitizer solutions being used. This is required by the Food Premises Regulation be in a food premises at all times. There are three different types of sanitizer test strips for the three different types of chemical sanitizer solutions: chlorine, quaternary ammonium and iodine test strips. Make sure you follow the manufacturer’s directions on how to use the test strips.

Chlorine Test Strips

Quaternary Ammonium Test Strips

Iodine Test Strips

Remember! If the “ppm” in the chemical sanitizer solution is too high, add water to dilute the solution. If the “ppm” is too low in the chemical sanitizer solution, add more chemical to strengthen the solution

Food Handler Certification Course Study Guide

Page 119 of 162

MACHINE DISHWASHING Commercial dishwashers, which are different from the dishwashers used at home, must be used in food premises. Generally, these types of dishwashers have shorter cycles, the water being used is hotter, thermometers are provided to indicate the water temperature, and different chemicals are added during the cycle. There are two types of commercial dishwashers: 1)

High Temperature Dishwasher: this machine uses detergent during the wash cycle and very hot water, or heat sanitizing (very hot water at a minimum of 82°C (180°F) or higher and be in contact with the dish, utensil or equipment for at least 10 seconds) for its sanitizing cycle.

Example of a High Temperature Dishwasher

Food Handler Certification Course Study Guide

Page 120 of 162

2)

Low Temperature Dishwasher: this machine uses detergent during the wash cycle and a chemical solution, or chemical sanitizing (“bleach” at 100 ppm, “quats” at 200 ppm or iodine at 25 ppm at a minimum of 24°C (75°F) or higher and be in contact with the dish, utensil or equipment for at least 45 seconds) for its sanitizing cycle.

Example of a Low Temperature Dishwasher

Remember! The machine itself must be constantly cleaned Always allow a complete cycle to finish; do not stop a cycle Potable (clean) water must be used during the wash and rinse cycles The machine’s spray arms (pictured below, left) must be cleared before use and able to spray water cleanly

Detergent and chemical sanitizer (if used) must always be available for use

Food Handler Certification Course Study Guide

Page 121 of 162

Washing Dishes, Utensils or Equipment In A Machine Dishwasher Scrape off any food or dirt

Pre-rinse or soak with clean, warm water

Load into machine and make sure all surfaces are exposed to the spray arms

Check the thermometers to ensure the water temperature during the wash cycle is between 60°C to 71°C (140°F to 160°F)

OR If machine is a high temperature dishwasher it uses hot water for sanitizing. Check the thermometer to ensure that the sanitizing rinse water temperature for the machine is at least 82°C (180°F) and in contact with the item for a minimum of 10 seconds

If machine is a low temperature dishwasher it uses chemicals for sanitizing. Chlorine bleach (100 ppm), quaternary ammonium (200 ppm) or iodine (25 ppm) solutions are injected into the sanitizing rinse. Check the thermometer to ensure that the sanitizing rinse water temperature for the machine is at least 24°C (75°F) and in contact with the item for a minimum of 45 seconds. Use sanitizer test strips to ensure the chemical solution is at the proper concentration

Air dry, ensuring item is completely dry before reusing. Any items that appear to still be soiled should be run through the cycle again

Food Handler Certification Course Study Guide

Page 122 of 162

MANUAL DISHWASHING Some food premises have their dishes, utensils or equipment washed by hand; otherwise known as manual dishwashing. Manual dishwashing can happen in either a three-compartment sink or a two-compartment sink.

Three-Compartment Sink In this type of sink, there are three separated sinks side-by-side, sharing one or more taps with hot and cold running water. A three-compartment sink is required in a food premises when the food premises uses multi-service articles. According to the Food Premises Regulation, a multi-service article is any container or eating utensil that is intended for repeated use in the service or sale of food. In other words, if the food premises is serving the food with reusable plates, spoons, forks, knives, cups, etc., then a three-compartment sink would be required.

Two-Compartment Sink In this type of sink, there are two separated sinks side-by-side, sharing one or more taps with hot and cold running water. A two-compartment sink can be used in a food premises provided that the food premises only uses single-service articles. According to the Food Premises Regulation, a single-use article is any container or eating utensil that is to be used only once in the service or sale of food. In other words, if the food premises is serving the food with disposable (plastic or paper) plates, spoons, forks, knives, cups, etc., then a two-compartment sink can be used.

Remember! Only dishwashing of dishes, utensils or equipment is to be done in a threecompartment or two-compartment sink. Handwashing is not allowed!

Food Handler Certification Course Study Guide

Page 123 of 162

Washing Dishes, Utensils or Equipment Manually Using A Three Compartment Sink

Scrape off any food or dirt from item

Use the first sink for washing. Scrub the item using soap/detergent and clean, warm water. If the suds are gone or the water gets dirty, change it Use the middle sink for rinsing. Use a thermometer to ensure that the water is at a minimum of 43°C (110° F). Make sure the soap/detergent is rinsed off the item completely. If the soap/detergent is not rinsed off completely, the sanitizer will not work properly

OR Use the third sink for sanitizing. If you use heat for sanitizing, use a thermometer to ensure that the water temperature is at a minimum of 77°C (171°F) and in contact with the item for a minimum of 45 seconds

Use the third sink for sanitizing. If you use chemicals for sanitizing, use a thermometer to ensure that the water temperature is at a minimum of 24°C (75°F) before you add one of the three approved chemicals to make a solution: chlorine bleach (100 ppm), quaternary ammonium (200 ppm) or iodine (25 ppm). The item must be in contact with the chemical solution for a minimum of 45 seconds. Use sanitizer test strips to ensure the chemical solution is at the proper concentration

Air dry, ensuring item is completely dry before reusing. Do not use a towel to dry

Washing Dishes, Utensils or Equipment Manually Using A Two Compartment Sink

Scrape off any food or dirt from item

Use the first sink for washing. Scrub the item using soap/detergent and clean, warm water. If the suds are gone or the water gets dirty, change it Rinse the item with warm water under a running tap with the water draining back into the first sink. Use a thermometer to ensure that the water is at a minimum of 43°C (110° F). Make sure the soap/detergent is rinsed off the item completely. If the soap/detergent is not rinsed off completely, the sanitizer will not work properly

OR Use the second sink for sanitizing. If you use heat for sanitizing, use a thermometer to ensure that the water temperature is at a minimum of 77°C (171°F) and in contact with the item for a minimum of 45 seconds

Use the second sink for sanitizing. If you use chemicals for sanitizing, use a thermometer to ensure that the water temperature is at a minimum of 24°C (75°F) before you add one of the three approved chemicals to make a solution: chlorine bleach (100 ppm), quaternary ammonium (200 ppm) or iodine (25 ppm). The item must be in contact with the chemical solution for a minimum of 45 seconds. Use sanitizer test strips to ensure the chemical solution is at the proper concentration

Air dry, ensuring item is completely dry before reusing. Do not use a towel to dry Food Handler Certification Course Study Guide

Preparing a Chlorine Sanitizer Solution A chlorine sanitizer solution is perhaps the easiest and most cost-effective chemical sanitizer solution to make. A jug of regular, unscented 5.25% bleach can make hundreds of litres of sanitizer solution! To prepare a sanitizer solution using chlorine bleach, add 2 mL of 5.25% chlorine bleach to every 1 L of water to make a sanitizing solution of 100 ppm. This would be the same as adding 9 mL (2 tsp) of 5.25% chlorine bleach to 4.5 L (1 gal) of water to make a sanitizing solution of 100 ppm. 5.25% chlorine means the chlorine has 5.25% sodium hypochorite as an active ingredient (the chlorine percentage can be found printed on the label of the container). To determine how much 5.25% chlorine bleach is required for a sanitizing solution of 100ppm, use the following formula:

10.5 x (litres of solution wanted) 5.25 [% chlorine]

=

millilitres (mL) of chlorine bleach required

Example: 100 ppm chlorine sanitizing solution 9 mL (2 tsp.) 5.25% bleach

4.5 L (1 gal.) water

Remember! Use chlorine sanitizer test strips to verify that the solution is at 100 ppm

Food Handler Certification Course Study Guide

Page 126 of 162

CLEANING AND SANITIZING EQUIPMENT Food processing equipment (ex. slicers, can openers, mixers) must be taken apart and each part cleaned and sanitized after each use or in-between tasks. This can happen more than four times a day! Sometimes equipment cannot be cleaned and sanitized in a two- or threecompartment sink or a dishwasher, as it is too big or heavy to be moved. These types of equipment are called “fixed” or “in-place” equipment.

For equipment being cleaned and sanitized in place, the strength of the sanitizer solution must be doubled (ex. 100 ppm chlorine solution becomes a 200 ppm)

Posted Instructions For Fixed Equipment According to the Food Premises Regulation, fixed equipment that is cleaned and sanitized in-place must have instructions posted in a place accessible to the person cleaning and sanitizing it. The instructions must include: the chemicals used for cleaning and sanitizing the strength of the chemical solutions to be used the length of time the equipment is to be exposed to the chemicals the procedures used for cleaning and sanitizing the equipment The posted instructions should be accessible; for example, where the cleaning supplies and water supply used to clean and sanitize in-place equipment is located

Food Handler Certification Course Study Guide

Page 127 of 162

Cleaning and Sanitizing Fixed Equipment

Unplug any electrical equipment Scrub non-food contact surfaces first, using soap/detergent and clean, warm water, followed by rinsing it of with clean, warm water

OR If you use heat (steam) for sanitizing, the temperature of the steam must be at a minimum of 82°C

If you use chemicals for sanitizing, the sanitizer solution must be doubled in strength: chlorine bleach at 200 ppm, quaternary ammonium at 400 ppm or iodine at 50 ppm. The equipment must be in contact with the chemical solution for a minimum of 45 seconds. Use sanitizer test strips to ensure the chemical solution is at the proper concentration

Scrub food contact surfaces next, using soap/detergent and clean, warm water, followed by rinsing it of with clean, warm water

OR If you use heat (steam) for sanitizing, the temperature of the steam must be at a minimum of 82°C

If you use chemicals for sanitizing, the sanitizer solution must be doubled in strength: chlorine bleach at 200 ppm, quaternary ammonium at 400 ppm or iodine at 50 ppm. The equipment must be in contact with the chemical solution for a minimum of 45 seconds. Use sanitizer test strips to ensure the chemical solution is at the proper concentration

Air dry both non-food contact and food contact surfaces, ensuring the item is completely dry before reusing. Do not use a towel to dry.

WIPING CLOTHS AND SPONGES If wiping cloths and sponges are not handled properly, they can be a source of pathogens and can spread pathogens to any surface they touch. Different wiping cloths or sponges should be used for food contact surfaces (ex. cutting boards) and non-food contact surfaces (ex. table tops).

Safety Tips: Properly Handling Wiping Cloths and Sponges Store in a chemical sanitizing solution at the proper concentration (chlorine bleach at 100 ppm, quaternary ammonium at 200 ppm, iodine at 25 ppm). Do not leave them on the counter, as a damp, used wiping cloth or sponge sitting on a counter can be a breeding ground for pathogens Rinse the wiping cloth or sponge under clean, running water before putting it back in the sanitizing solution Store wiping cloths or sponges used for food contact surfaces in a different bucket than the ones used for non-food contact surfaces Make a fresh batch of sanitizing solution periodically throughout the day as needed. Dirty wiping cloths or sponges continuously put in the bucket weakens the sanitizer solution Use different coloured buckets to keep the food contact and non-food contact solutions from getting mixed up If using a spray bottle to store sanitizing solution ensure that it is properly labelled. Make sure a new solution for the spray bottle is made daily as the strength of the sanitizing solution weakens after 24 hrs. Replace wiping cloths and sponges on a regular basis. This may be more than once a day!

Replace wiping cloths with new, clean ones on a regular basis Use different coloured buckets Label spray bottles and make new solution daily

GARBAGE AND WASTE MANAGEMENT Use plastic or wet-strength bags Put garbage in leak-proof, non-absorbent, rodent-proof containers Close the bag and secure it tightly Wash hands after taking out garbage Wash, rinse and sanitize garbage containers as often as necessary to discourage pests and odour Large bins should be emptied at least twice weekly or as needed to prevent the garbage from overflowing and to prevent a strong odour

All liquid waste must be disposed of in a sanitary manner. This includes grease and mop water Clean out grease traps regularly to prevent overflows. Do not dispose of grease down a drain. Have a waste removal company dispose of the grease

CHAPTER 11 Proper Food Premises Operation

Food Handler Certification Course Study Guide

Page 133 of 162

PROPER FOOD PREMISES OPERATION There are a lot of factors involved to have a food premises operating in proper, working condition. Some of these factors involve the safe practices of food handlers, and some involve the actual, physical premises itself.

Lighting The lighting levels in a food premises should be bright enough for food handlers to clearly see what tasks they are doing. This includes the lighting being adequate in every section of the food premises for cooking, cleaning and serving at all times it is open for business. According to the Food Premises Regulation, the levels of illumination required under the Ontario Building Code must be maintained during all hours of operation of a food premises. For exact requirements and further information of the Ontario Building Code, contact the local municipal building department.

Storage Space There should be enough storage space for all food and other materials and equipment in the food premises; the correct quantity should be ordered and not be overflowing within the room of the premises. As well, any materials or equipment (ex. broken stove, furniture, containers) not regularly used in the room should not be stored there and be removed from the room.

Food Handler Certification Course Study Guide

Page 134 of 162

Mechanical Ventilation Mechanical ventilation is required to remove heat, steam, condensation, smoke, odours and fumes, all of which are vented to outside of the food premises. These ventilation systems would be found over cooking equipment (ex. stoves, ovens), dishwashers, and in each washroom. Some examples of mechanical ventilation systems include exhaust fans, ducts, canopies, hoods and filters.

According to the Food Premises Regulation, the ventilation systems in every food premises shall be maintained so that the premises do not become a health hazard. Therefore, the equipment must be constructed of corrosion-resistant and easily cleanable materials, and must be cleaned as often as necessary. This may be more than three times a week!

Walls and Ceilings Walls and ceilings must be made of sound and tight construction and must be kept in good repair. It must be constructed of corrosion-resistant and easily cleanable materials, like tiles, stainless steel, or walls and ceilings painted with water-resistant paint.

According to the Food Premises Regulation, walls and ceilings should be cleaned and maintained in a sanitary condition. Cleaning should be done as often as necessary; this may be more than once a day! Food Handler Certification Course Study Guide

Page 135 of 162

Floors Floors and floor coverings should be constructed of corrosion-resistant and easily cleanable materials, like tiles or concrete floors painted with waterresistant paint. Rubber or vinyl mats (as seen in picture on right, below) are allowed on these floors provided they are kept in a clean and sanitary condition. Carpet mats or cardboard laid on the floor are not permitted for use. According to the Food Premises Regulation, floors or floor coverings must be tight, smooth and nonabsorbent in rooms where food is prepared, utensils are washed and in rooms where hand washing and toilet fixtures are located. The only place carpet is allowed in a food premises is where food is served (not prepared), provided they are kept in a clean and sanitary condition.

Food Contact Equipment and Utensils Food contact equipment and utensils must be made of sound and tight construction and must be kept in good repair. It must be constructed of corrosionresistant and easily cleanable materials, and must be cleaned and sanitized after each use. As well, there should be no cracks, chips or open seams on any equipment or utensils.

Live Animals Live birds and animals are not allowed in a food premises where food is being prepared.

Live animals are not allowed in food premises

According to the Food Premises Regulation, the only exceptions to this law are: service dogs serving as a guide for a blind person or for a person with another medical disability who requires the use of a service dog, provided they are only in the section of the food premises where food is served, sold or offered for sale live aquatic species displayed or stored in sanitary tanks, such as fish or live lobsters (as pictured above, right) any food premises that the Health Department gives permission to have live birds or animals

Service dogs are permitted where food is served but not prepared

Live lobsters are permitted where they are stored in sanitary tanks

CHAPTER 12 Pests and Preventing Pest Problems

Food Handler Certification Course Study Guide

Page 141 of 162

PESTS A pest infestation in a food premises is considered a health hazard to humans because pests have the ability to spread pathogens to food and food contact surfaces. If a pest infestation is found in a food premises, it can be ordered closed by the Public Health Inspector. Aside from food, pests can damage the building and equipment in a food premises by gnawing through rubber, aluminum, walls, plastic and wood. The most common pests that affect food premises are: cockroaches, flies and rodents. This food premises must be re-inspected due to inadequate pest control (magnified)

Cockroaches The most common cockroaches in Ontario range in size from 1.2 – 1.6 cm, and are able to survive with very little food or water. Cockroaches live and breed anywhere that is dark, warm, moist and hard-to-clean.

The German Cockroach is a common cockroach found in Ontario

Cockroaches can carry pathogens such as Salmonella bacteria and can spread it to food or food contact surfaces. If the cockroaches are seen in the broad daylight, it is a general sign of an infestation. Did you know? One female cockroach is able to lay eggs and produce over 300 babies over its lifetime Food Handler Certification Course Study Guide

Page 142 of 162

Flies The most common flies in Ontario range in size from 6 – 9 mm, and are especially a concern in the summer (as they generally do not survive in the winter).

Flies can carry pathogens such as Salmonella and Giardia and can spread it to food or food contact surfaces. They are attracted to the odours of food, garbage, and human and animal waste, and when they land on it, they vomit on it to soften it up before ingesting it. As a result, they can contaminate other food or surfaces through their mouth, feet, hair, feces and vomit itself. Did you know? One female fly is able to lay eggs and produce over 500 babies over its lifetime

Rodents The rodents that are of most concern in food premises are mice and rats. The most common mice in Ontario range in size from 5 – 10 cm, while the most common rats in Ontario range in size from 15 – 25 cm (not including the tail, which can be just as long as the body).

Rodents can carry pathogens such as Salmonella and Hantavirus and can spread it to food or food contact surfaces. Rodents can multiply quickly and will eat almost anything, leaving thousands of droppings along the way. Did you know? One female mouse is able to have up to 800 babies over one year Food Handler Certification Course Study Guide

Page 143 of 162

PREVENTING PEST PROBLEMS Preventing a pest problem is more effective than simply waiting for the problem to happen and reacting to it. The following are steps to prevent a pest problem.

Physical Barriers Creating physical barriers to keep pests out of the food premises is the most effective method for prevention. This includes: Installing tight fitting screens on doors and windows, and using weather stripping to stop any gaps under or around them Repairing and filling in any holes in walls. Steel wool or sheet metal around pipes and other openings can also be used to plug the holes because pests do not like to bite through metal Making sure doors to the exterior of the food premises are shut at all times (with the exception of deliveries). If it gets too warm in the premises, a screen door can be installed provided there are no holes or gaps on the door itself

Identifying Pest Infestations In the event there is a pest infestation in a food premises, it can be identified through simple signs. This includes: The presence of feces (droppings), especially under and around counters, surfaces and equipment Bite marks on food products, packaging, or equipment Greasy, smudge marks along walls left by rodents Seeing pests during the day. Pests like to hide and not be seen; if they are seen in broad daylight, it can be a sign of a major infestation Did you know? You can identify different pests by the way their feces (droppings) look: Cockroach feces looks is dark and looks like pepper Mice feces is dark and the looks like a rice grain Rat feces is dark and looks like a coffee bean

Food Handler Certification Course Study Guide

Page 144 of 162

Removing Nesting Areas If pests have adequate food, water and shelter in a specific area, they are likely to want to live or “nest” there. Some ways to remove nesting areas include: Cleaning and sanitizing all food contact surfaces throughout the day and when the food premises closes Cleaning and sanitizing all non-food contact surfaces, especially hard-toreach places. This includes removing pieces of food and grease under equipment Removing any unused equipment from the food premises. These can act as a place of shelter for the pests Removing garbage from inside the food premises as soon as possible and keeping it in tightly covered, pest proof containers outside of the food premises Repairing water leaks and cleaning all spills immediately Making sure food being received in the food premises does not have pests and storing food, especially dry goods such as cereal grains and pasta, in pest-proof storage containers

Removing nesting areas includes storing food properly

Remember! Pieces of food and grease left under equipment (ex. stove, refrigerator) will: make it hard to keep pests out of the kitchen provide a source of food for pests attract pests Food Handler Certification Course Study Guide

Page 145 of 162

Treatment From A Pest Control Operator Treatment from a private pest control operator is recommended, even if there is no infestation in the food premises. Pest control operators can do things like set traps and keep track of the progress of treatment.

Pest control operators can set traps, like “bug lights” and rodent traps

Aside from having the ability to remove a pest infestation, they are also pros in identifying potential areas where pests can nest.

Safety Tip: Pesticides Pesticides are chemicals used to control insects and rodents. Chemical pesticides are not a substitute for good sanitation. Do not try to solve pest problems by using only pesticides. Pesticides can be dangerous to food, employees and customers. If pesticides are being used, make sure they are kept in the original labelled container and stored away from food
