Cross-contamination and allergens: key rules to remember
Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗
Protecting food
- All food must be protected from contamination and handled in a sanitary way without risk of spoilage.
- "Contaminate" includes introducing foreign matter, poisons, pests, disease-causing micro-organisms or toxins.
- Food already served to one customer must not be served to another unless it was in a container that prevents contamination.
- Potentially hazardous food that was served to a customer must never be re-served, even in a protective container.
Cross-contamination
- Germs spreading from raw food to other food is called cross-contamination.
- Keep raw meat, poultry and seafood separate; store them sealed and below fruit, vegetables and ready-to-eat food.
- Use one cutting board for raw meat and a different one for ready-to-eat foods.
- Wash fruit and vegetables under cool running water before eating or cutting, even if they will be peeled; scrub firm produce with a clean brush.
- Never put cooked meat back on an unwashed surface that held raw meat (HealthLinkBC E. coli file).
Food safety plan (storage and preparation controls)
- Cover food with plastic wrap or food-grade material; move opened canned food into food-grade containers; reseal opened bags or use pest-proof containers.
- Store chemicals below, away and separately from food.
- Sanitize food contact surfaces and equipment before use.
Allergens
- Keep an up-to-date ingredient list for all menu items and make sure staff know about allergy issues.
