Ontario Food Handler Certificate Cross-Contamination Prevention 6

Question 1

What is the Ontario requirement for the number of priority food allergens that must be declared?

Accepted Answer

11 priority allergens plus sulphites and mustard

Answer

Canada requires declaration of 11 priority allergens (peanuts, tree nuts, milk, eggs, wheat/triticale, soy, sesame, seafood — fish, crustaceans, molluscs) plus sulphites and mustard on food labels and menus.

Question 2

What is indirect cross-contamination?

Accepted Answer

When contaminants are transferred via an intermediate surface, utensil, or hand

Answer

Indirect cross-contamination occurs when bacteria are transferred through an intermediary — such as a cutting board, knife, cloth, or food handler's hands — rather than through direct food-to-food contact.

Question 3

In Ontario, what labeling is required when food is transferred from its original packaging to a new container?

Accepted Answer

The common name of the food and any allergen information must be maintained

Answer

When food is removed from its original packaging, the common name and all allergen information must be transferred to the new container to prevent accidental serving to allergen-sensitive customers.

Question 4

How should food handlers prevent cross-contamination when using a shared handwashing sink?

Accepted Answer

Use the taps with a paper towel after washing hands, and never place food items near the sink

Answer

Tap handles can be recontaminated after handwashing. Using a paper towel to turn off taps prevents recontamination. Food should never be placed near or in handwashing sinks.

Question 5

What is the risk of reusing single-use items such as disposable containers or plastic wrap?

Accepted Answer

Reuse can harbor bacteria from previous use, and the items may not withstand repeated cleaning

Answer

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.
