Preventing 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 ↗

ss. 23 and 27

  • All food must be protected from contamination and handled in a sanitary way; contaminated or unfit food must not be served, sold, processed, displayed or stored for eating.
  • Food already served may be re-served only if it is low-risk, uncontaminated, and either served each time in a container designed to prevent contamination or individually packaged, unopened and untampered.

s. 3.5.1 Microbial contamination

  • Restrict access to food preparation areas to designated food handlers as much as possible.
  • Self-serve food (other than unprocessed produce) must be protected by packaging, display cases or sneeze guards and provided with suitable utensils.
  • Avoid touching exposed ready-to-eat food with bare hands; use clean, sanitized tongs, spatulas, disposable gloves or other dispensers.
  • Keep raw or unprocessed food separate from ready-to-eat food.
  • Wash raw fruits and vegetables thoroughly in potable water before cutting, combining, cooking or serving them ready to eat (whole produce sold for customers to wash themselves is exempt).
  • Never let food touch utensils or equipment that have not been cleaned and sanitized; clean and sanitize a tasting utensil before each use.
  • Food returned by a customer may not be sold to another customer unless it is low-risk and still in its unopened original package (such as creamers, crackers or condiments).

s. 3.5.2 and Appendix C Allergens

  • Operators should know the common food allergens, which can be life-threatening; if a customer asks, provide the ingredient list and suggest they consult their physician.
  • Priority allergens listed: peanuts, tree nuts, sesame seeds, milk, eggs, seafood (fish, crustaceans, shellfish), soy, wheat, mustard and sulphites.
  • Undeclared allergens can come from incomplete cleaning of surfaces and utensils (carry-over), recipe substitutions not reflected on labels, or wrong labels.

s. 4.2.5 (d) Wiping cloths

  • Cloths used to wipe food-contact surfaces should not be used for other jobs such as wiping raw animal foods, and should be kept in sanitizing solution between uses.

s. 42 (temporary food establishments)

  • Food-contact surfaces are washed and sanitized at least daily and between handling raw and cooked foods on the same surface; self-serve condiments come from squeeze or pump containers or self-closing lids.
