415C Food Safety — Questions and Answers
Question 1: According to Canadian food safety regulations, what is the temperature range known as the 'danger zone' where bacteria multiply most rapidly?
- 0°C to 30°C
- 4°C to 60°C (Correct answer)
- 10°C to 50°C
- 20°C to 70°C
Correct answer: 4°C to 60°C
The danger zone in Canadian food safety is defined as 4°C to 60°C. Within this temperature range, bacteria can double in number every 15 to 20 minutes. Food must pass through this range as quickly as possible.
Question 2: What is the maximum time potentially hazardous food can remain in the danger zone before it must be discarded?
- 1 hour
- 2 hours (Correct answer)
- 4 hours
- 6 hours
Correct answer: 2 hours
According to Canadian food safety guidelines, potentially hazardous food that has been in the danger zone (4°C to 60°C) for a cumulative total of 2 hours should be served immediately or discarded. Some jurisdictions allow up to 4 hours under specific conditions.
Question 3: When cooling cooked food, what is the two-stage cooling requirement under Canadian food safety standards?
- From 60°C to 20°C within 4 hours, then 20°C to 4°C within 6 hours
- From 60°C to 20°C within 2 hours, then 20°C to 4°C within 4 hours (Correct answer)
- From 60°C to 10°C within 2 hours, then 10°C to 4°C within 2 hours
- From 60°C to 4°C within 4 hours total, no stages required
Correct answer: From 60°C to 20°C within 2 hours, then 20°C to 4°C within 4 hours
Canadian food safety standards require a two-stage cooling process: food must cool from 60°C to 20°C within 2 hours, then from 20°C to 4°C within an additional 4 hours (6 hours total maximum). This limits time in the most dangerous temperature ranges.
Question 4: What does HACCP stand for in the Canadian food service industry?
- Health and Cleanliness Compliance Program
- Hazard Analysis and Critical Control Points (Correct answer)
- Hygiene Assessment and Contamination Control Plan
- Healthy And Clean Cooking Practices
Correct answer: Hazard Analysis and Critical Control Points
HACCP (Hazard Analysis and Critical Control Points) is a systematic preventive approach to food safety that identifies, evaluates, and controls hazards throughout the food production process. It is recognized and recommended by Health Canada.
Question 5: What is the correct order for washing dishes by hand in a commercial kitchen according to Canadian food safety standards?
- Rinse, wash, sanitize, air dry
- Scrape/pre-rinse, wash in hot soapy water, rinse in clean hot water, sanitize, air dry (Correct answer)
- Wash in hot water, sanitize, rinse, towel dry
- Sanitize, wash, rinse, air dry
Correct answer: Scrape/pre-rinse, wash in hot soapy water, rinse in clean hot water, sanitize, air dry
The correct five-step procedure is: (1) scrape and pre-rinse, (2) wash in hot soapy water (at least 44°C), (3) rinse in clean hot water, (4) sanitize using an approved chemical sanitizer or hot water (77°C for 30 seconds), and (5) air dry on a clean rack.
Question 6: What is cross-contamination and how is it primarily prevented in a kitchen?
- Mixing two different cuisines; prevented by separate menus
- Transfer of harmful substances from one food to another; prevented by using separate cutting boards, utensils, and proper storage (Correct answer)
- Adding too many ingredients to a dish; prevented by following recipes
- Using expired ingredients; prevented by checking best-before dates
Correct answer: Transfer of harmful substances from one food to another; prevented by using separate cutting boards, utensils, and proper storage
Cross-contamination is the transfer of harmful bacteria or allergens from one food item, surface, or piece of equipment to another. It is prevented by using colour-coded cutting boards, separate utensils for raw and cooked foods, proper storage (raw below cooked), and thorough handwashing.
