Ontario Food Handler Certificate — Questions and Answers
Question 1: What should be included on the label of a spray bottle containing diluted sanitizer?
- Nothing — it is obvious what it contains
- The name of the person who prepared it
- The name of the chemical, its concentration, and any hazard warnings (Correct answer)
- Only the date it was prepared
Correct answer: The name of the chemical, its concentration, and any hazard warnings
All secondary containers (spray bottles, buckets) must be clearly labeled with the chemical name, concentration, and hazard warnings. Unlabeled containers can lead to accidental misuse, chemical mixing, or ingestion.
Question 2: What are the Ontario requirements for labeling food prepared for retail sale at the premises?
- No labeling required if sold on the premises where prepared
- Product name, list of ingredients including allergens, and best before date (if shelf life is 90 days or less) (Correct answer)
- Only the date of preparation
- Only a price sticker is needed
Correct answer: Product name, list of ingredients including allergens, and best before date (if shelf life is 90 days or less)
Foods prepared and packaged for retail sale at the premises must display the product name, complete ingredient list with priority allergen declarations, and a best before date if the shelf life is 90 days or less.
Question 3: How should raw eggs be stored in a food premises?
- On the counter at room temperature
- In the refrigerator at 4°C or below, in their original carton (Correct answer)
- In the freezer for maximum freshness
- In a bowl on the prep table
Correct answer: In the refrigerator at 4°C or below, in their original carton
Eggs must be stored in the refrigerator at 4°C or below in their original carton, which protects them from damage, absorbing odors, and moisture loss. The carton also displays the best before date.
Question 4: How should vacuum-packed foods be stored?
- In the freezer only
- According to the manufacturer's instructions, typically refrigerated at 4°C or below, and checked for package integrity (Correct answer)
- At room temperature since they are sealed
- Under a heat lamp to maintain freshness
Correct answer: According to the manufacturer's instructions, typically refrigerated at 4°C or below, and checked for package integrity
Vacuum-packed foods must be stored according to the manufacturer's guidelines, usually refrigerated. The anaerobic environment in vacuum packaging can support Clostridium botulinum growth if temperature-abused. Package integrity must be monitored.
Question 5: Which of the following is a priority allergen recognized in Canada?
- Pepper
- Avocado
- Garlic
- Mustard (Correct answer)
Correct answer: Mustard
Mustard is one of Canada's 14 priority food allergens and must be clearly declared on food labels.
Question 6: What is the purpose of a quaternary ammonium (quat) test strip?
- To check detergent levels
- To test food temperatures
- To test water hardness
- To measure the concentration of quaternary ammonium sanitizer to ensure it is at the effective level (Correct answer)
Correct answer: To measure the concentration of quaternary ammonium sanitizer to ensure it is at the effective level
Quat test strips measure the concentration of quaternary ammonium sanitizer in solution. The typical effective range is 200 ppm. Using the correct test strip for the specific sanitizer type is essential.
Question 7: Why must food-contact surfaces be air dried after sanitizing rather than towel dried?
- Towels can recontaminate the sanitized surface with bacteria (Correct answer)
- Air drying is faster
- There is no difference between the two methods
- Air drying uses less water
Correct answer: Towels can recontaminate the sanitized surface with bacteria
Towels, even clean ones, can transfer bacteria back onto sanitized surfaces. Air drying allows the sanitizing solution to remain in contact with the surface longer, maximizing its effectiveness.
Question 8: What is the risk of reusing single-use items such as disposable containers or plastic wrap?
- There is no risk if they look clean
- Single-use items can be reused up to three times
- Reuse can harbor bacteria from previous use, and the items may not withstand repeated cleaning (Correct answer)
- Reuse is only a cost concern
Correct answer: Reuse can harbor bacteria from previous use, and the items may not withstand repeated cleaning
Single-use items are designed for one use and cannot be effectively cleaned and sanitized. Reuse can harbor bacteria in cracks and crevices, and the materials may break down, creating physical hazards.
Question 9: What does the acronym YOPI stand for in food safety?
- Yearly Operational Procedures Inspection
- Young, Old, Pregnant, Immunocompromised (Correct answer)
- Yield, Observe, Protect, Inspect
- Your Obligation to Prevent Illness
Correct answer: Young, Old, Pregnant, Immunocompromised
YOPI stands for Young, Old, Pregnant, and Immunocompromised — the four population groups most vulnerable to serious complications from food-borne illness.
Question 10: What is the maximum temperature at which a refrigerator should operate in a food premises?
- 10°C (50°F)
- 0°C (32°F)
- 4°C (40°F) (Correct answer)
- 7°C (45°F)
Correct answer: 4°C (40°F)
Refrigerators in food premises must operate at 4°C (40°F) or below. This temperature slows bacterial growth to safe levels and keeps potentially hazardous foods out of the danger zone.
Question 11: How should ice scoops be stored when not in use?
- In a designated clean holder outside the ice bin (Correct answer)
- Inside the ice bin with the handle touching the ice
- Anywhere convenient near the ice machine
- On top of the ice machine
Correct answer: In a designated clean holder outside the ice bin
Ice scoops should be stored in a clean, designated holder outside the ice bin to prevent contamination. Handles left in ice can introduce bacteria from hands, and the scoop itself stays cleaner when stored separately.
Question 12: A food handler with asymptomatic Hepatitis A (no symptoms but confirmed carrier) wants to return to work. What is required?
- They must obtain written clearance from a physician or public health authority (Correct answer)
- They can return immediately since they have no symptoms
- They can return after 48 hours
- They only need their supervisor's approval
Correct answer: They must obtain written clearance from a physician or public health authority
Asymptomatic carriers of Hepatitis A can still shed the virus and contaminate food. Medical clearance from a physician or public health authority is required before returning to food handling duties.
Question 13: What is the correct order of steps for proper handwashing?
- Rinse, soap, air dry
- Soap, rinse, dry
- Wet, soap, scrub 20 seconds, rinse, dry with paper towels (Correct answer)
- Wet, scrub, sanitize
Correct answer: Wet, soap, scrub 20 seconds, rinse, dry with paper towels
The correct handwashing procedure is: wet hands with warm water, apply soap, scrub all surfaces for at least 20 seconds (including between fingers and under nails), rinse thoroughly, and dry with single-use paper towels.
Question 14: What is the proper method for washing fruits and vegetables to reduce contamination risk?
- Wash them with bleach solution
- Soak them in soapy water
- Wipe them with a damp cloth
- Rinse them under clean running water and scrub firm produce with a clean brush (Correct answer)
Correct answer: Rinse them under clean running water and scrub firm produce with a clean brush
Fruits and vegetables should be rinsed under clean running water. Firm produce like potatoes and melons should be scrubbed with a clean produce brush. Soap and bleach are not recommended for produce.
Question 15: Why should food handlers avoid using the same sink for handwashing and food preparation?
- Handwashing can contaminate the sink with pathogens that may transfer to food or food-contact items (Correct answer)
- It wastes water
- It is inconvenient
- There is no reason; the same sink can serve both purposes
Correct answer: Handwashing can contaminate the sink with pathogens that may transfer to food or food-contact items
Handwashing washes bacteria and contaminants into the sink. Using the same sink for food preparation risks transferring these pathogens to food. Ontario regulations require separate handwashing stations.
Question 16: Peanuts belong to which food group?
- Seeds
- Tree nuts
- Legumes (Correct answer)
- Grains
Correct answer: Legumes
Peanuts are legumes, not tree nuts, which is why someone with a peanut allergy may or may not also react to tree nuts.
Question 17: Why is it important to clean drains in a food premises regularly?
- Drains can harbor bacteria, create foul odors, and attract pests if not cleaned regularly (Correct answer)
- Drains clean themselves with the water that flows through them
- Drain cleaning is only needed annually
- Only for aesthetic purposes
Correct answer: Drains can harbor bacteria, create foul odors, and attract pests if not cleaned regularly
Drains accumulate organic matter that supports bacterial growth, produces odors, and attracts pests like flies and cockroaches. Regular cleaning with appropriate drain cleaners prevents these issues.
Question 18: Under Ontario's Food Premises Regulation, what must an operator do when a food-borne illness outbreak is suspected?
- Notify the local Medical Officer of Health (Correct answer)
- Contact the Ministry of Agriculture
- Discard all food on the premises
- Close the establishment immediately
Correct answer: Notify the local Medical Officer of Health
Ontario regulation requires that suspected food-borne illness outbreaks be reported to the local Medical Officer of Health, who will coordinate the investigation and response.
Question 19: What is the minimum internal cooking temperature for whole poultry in Ontario?
- 63°C (145°F)
- 68°C (155°F)
- 74°C (165°F) (Correct answer)
- 71°C (160°F)
Correct answer: 74°C (165°F)
Whole poultry must reach a minimum internal temperature of 74°C (165°F) to destroy Salmonella and other harmful bacteria. This applies to chicken, turkey, duck, and all other poultry.
Question 20: How should dry goods like flour and sugar be stored after opening their original packaging?
- Transferred to clean, labeled, food-grade containers with tight-fitting lids (Correct answer)
- Placed in any available container
- Kept in the bag with the top folded over
- Left in the opened bag on the shelf
Correct answer: Transferred to clean, labeled, food-grade containers with tight-fitting lids
Once opened, dry goods should be transferred to clean, food-grade containers with tight-fitting lids to prevent pest contamination, moisture absorption, and cross-contamination. Containers must be labeled with the product name.
Question 21: What is the correct procedure for preparing a chlorine sanitizing solution?
- Mix bleach and hot water until it smells strong
- Mix the manufacturer's recommended amount of bleach with cool or lukewarm water and verify concentration with test strips (Correct answer)
- Mix bleach with detergent for a combined cleaning-sanitizing solution
- Pour bleach directly onto surfaces
Correct answer: Mix the manufacturer's recommended amount of bleach with cool or lukewarm water and verify concentration with test strips
Chlorine sanitizer should be mixed with cool or lukewarm water (hot water causes chlorine to evaporate). The concentration must be verified with test strips. Bleach should never be mixed with other chemicals.
Question 22: What precaution should food handlers take regarding personal medications?
- Medications can be stored anywhere as long as they are in original containers
- Take medications at their workstation if needed quickly
- Keep medications in their pocket for convenience
- Store medications in a designated area away from food, clearly labeled, and never use them in food preparation areas (Correct answer)
Correct answer: Store medications in a designated area away from food, clearly labeled, and never use them in food preparation areas
Personal medications must be stored separately from food and food preparation areas to prevent accidental contamination. They should be in labeled containers in a designated personal area.
Question 23: What type of food-borne illness is caused by toxins produced by bacteria before the food is eaten?
- Chemical contamination
- Infection
- Toxin-mediated infection
- Intoxication (Correct answer)
Correct answer: Intoxication
Intoxication occurs when bacteria produce toxins in food before consumption. Staphylococcus aureus is a common example, causing symptoms within hours.
Question 24: A food handler has a small cut on their finger. What is the proper procedure?
- They cannot work until it heals completely
- Apply hand sanitizer to the cut and continue working
- Cover the cut with a waterproof bandage and wear a disposable glove over it (Correct answer)
- Wrap the finger in a cloth and continue working
Correct answer: Cover the cut with a waterproof bandage and wear a disposable glove over it
Cuts must be covered with a waterproof bandage (preferably brightly colored for visibility) and then a disposable glove worn over it to prevent wound bacteria from contaminating food.
Question 25: What should you do if you notice ice crystals or freezer burn on frozen food?
- The food is unsafe and must be discarded immediately
- Add extra seasoning to mask the freezer burn taste
- Freezer burn makes food more nutritious
- Ice crystals may indicate thawing and refreezing — evaluate for safety; freezer burn affects quality but not necessarily safety (Correct answer)
Correct answer: Ice crystals may indicate thawing and refreezing — evaluate for safety; freezer burn affects quality but not necessarily safety
Large ice crystals can indicate the food was thawed and refrozen, which is a safety concern. Freezer burn (dry, discolored patches) primarily affects quality and taste but does not necessarily make food unsafe if it remained frozen.
Question 26: Which of the following is TRUE about bare-hand contact with ready-to-eat food?
- It is always acceptable if hands are washed
- It is only restricted for workers with cuts
- It is permitted for foods that will be cooked later
- It should be minimized; utensils, tongs, or gloves should be used instead (Correct answer)
Correct answer: It should be minimized; utensils, tongs, or gloves should be used instead
Bare-hand contact with ready-to-eat food should be avoided whenever possible. Utensils, tongs, deli paper, or disposable gloves provide a barrier between hands and food that will not be further cooked.
Question 27: A food handler is preparing a meal for a customer with a peanut allergy. Which action is most critical?
- Simply avoiding whole peanuts in the dish
- Adding extra seasoning to mask any peanut flavor
- Using fresh, clean utensils and surfaces that have not contacted peanuts or peanut products (Correct answer)
- Cooking the food at a higher temperature to destroy the allergen
Correct answer: Using fresh, clean utensils and surfaces that have not contacted peanuts or peanut products
Allergen proteins are not destroyed by heat. Fresh, uncontaminated equipment must be used. Even trace amounts from shared surfaces can trigger severe anaphylaxis in sensitive individuals.
Question 28: A food handler reports having diarrhea and vomiting. What should the operator do according to Ontario regulations?
- Allow them to work if they wear gloves
- Let them decide if they feel well enough to work
- Assign them to cashier duties only
- Exclude them from working with food until symptom-free for at least 24 hours (Correct answer)
Correct answer: Exclude them from working with food until symptom-free for at least 24 hours
Ontario regulations require that food handlers with symptoms of vomiting or diarrhea be excluded from food handling duties until they have been symptom-free for at least 24 hours to prevent contamination.
Question 29: Which of the following is a proper hair restraint for food handlers?
- A hair net or clean hat that fully covers the hair (Correct answer)
- A baseball cap worn backwards
- Hair tied in a ponytail without a net
- A headband that holds back bangs only
Correct answer: A hair net or clean hat that fully covers the hair
A hair net or clean hat that fully covers the hair prevents hair from falling into food. Hair can carry Staphylococcus aureus and other bacteria.
Question 30: How should garbage containers be maintained in a food premises?
- Lined with plastic bags, emptied frequently, cleaned and sanitized regularly, with tight-fitting lids (Correct answer)
- Left open for easy access during busy periods
- Emptied once a week
- Cleaned only when they smell bad
Correct answer: Lined with plastic bags, emptied frequently, cleaned and sanitized regularly, with tight-fitting lids
Garbage containers must be lined, emptied frequently to prevent overflow, cleaned and sanitized regularly to remove bacteria and odors, and fitted with tight-fitting lids to prevent pest access and contain odors.
