Ontario Food Handler Certificate Cross-Contamination Prevention 4 — Questions and Answers
Question 1: A food handler is preparing a meal for a customer with a peanut allergy. Which action is most critical?
- 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
- Adding extra seasoning to mask any peanut flavor
- Simply avoiding whole peanuts in the dish
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 2: Why should raw meat and poultry be prepared on surfaces separate from produce and ready-to-eat foods?
- Raw meat has a strong odor that transfers to other foods
- Raw meat and poultry commonly carry pathogenic bacteria that can transfer to foods eaten without further cooking (Correct answer)
- It is a preference, not a requirement
- Separate preparation is only needed for chicken
Correct answer: Raw meat and poultry commonly carry pathogenic bacteria that can transfer to foods eaten without further cooking
Raw meat and poultry frequently carry pathogens like Salmonella, E. coli, and Campylobacter. Produce and ready-to-eat foods are consumed without further cooking, so any transferred bacteria will not be destroyed.
Question 3: How should ice scoops be stored when not in use?
- Inside the ice bin with the handle touching the ice
- In a designated clean holder outside the ice bin (Correct answer)
- On top of the ice machine
- Anywhere convenient near 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 4: What is the primary risk of using the same oil for deep-frying different foods without consideration for allergens?
- The oil will taste bad
- Allergen proteins from one food (e.g., shrimp) can transfer to another food (e.g., French fries) through the shared oil (Correct answer)
- The oil becomes too hot
- There is no risk as heat destroys allergens
Correct answer: Allergen proteins from one food (e.g., shrimp) can transfer to another food (e.g., French fries) through the shared oil
Shared fryer oil can transfer allergen proteins between foods. A customer with a shellfish allergy could have a reaction from French fries cooked in oil previously used for shrimp.
Question 5: What should be done with a container of sanitizer solution used for wiping food-contact surfaces?
- Replace it once a week
- Test its concentration regularly and replace it when dirty or when concentration drops below effective levels (Correct answer)
- Replace it at the end of each month
- It never needs to be replaced if it looks clean
Correct answer: Test its concentration regularly and replace it when dirty or when concentration drops below effective levels
Sanitizer solution loses strength over time and with use. The concentration should be tested with test strips regularly (at least at the start of each shift) and replaced when dirty or below the effective concentration.
Question 6: A customer informs the server they have celiac disease. What must the kitchen staff be aware of?
- Celiac disease is not serious and no special precautions are needed
- All sources of gluten must be eliminated, including cross-contact from shared equipment, surfaces, and cooking oils (Correct answer)
- Only obvious wheat products need to be avoided
- Cooking food at high temperatures eliminates gluten
Correct answer: All sources of gluten must be eliminated, including cross-contact from shared equipment, surfaces, and cooking oils
Celiac disease requires complete avoidance of gluten. Even trace amounts from cross-contact through shared cutting boards, utensils, fryer oil, or cooking water can cause a severe autoimmune reaction.
