FOODSAFE Cross-Contamination Prevention 3

Question 1

How should a food handler manage allergen cross-contact in the kitchen?

Accepted Answer

Use separate utensils, clean and sanitize surfaces, and prepare allergen-free orders first or in a designated area

Answer

Allergen cross-contact can cause severe reactions even from trace amounts. Using separate utensils, thoroughly cleaning surfaces, and preparing allergen-free orders with dedicated equipment prevents cross-contact with allergenic proteins.

Question 2

Which of the following is an example of cross-contamination through a food handler?

Accepted Answer

A cook handles raw fish, does not wash hands, and then plates a cooked steak

Answer

The cook's unwashed hands transfer bacteria from raw fish directly to the cooked steak. This is handler-mediated cross-contamination — one of the most common types in food service operations.

Question 3

What is the best practice for handling produce that will be eaten raw?

Accepted Answer

Wash thoroughly under running water, use separate cutting boards designated for produce, and store away from raw meats

Answer

Raw produce must be thoroughly washed under running water to remove soil, bacteria, and pesticide residues. Using designated cutting boards prevents cross-contamination from raw meats, and proper storage keeps it safe.

Question 4

Why should food handlers avoid preparing food for others if they have an infected wound on their hands?

Accepted Answer

Infected wounds contain high concentrations of Staphylococcus aureus, which can contaminate food and cause staphylococcal food poisoning

Answer

Infected wounds, especially those with pus, contain extremely high concentrations of Staphylococcus aureus. If these bacteria enter food, they can produce heat-stable toxins that cause food poisoning even after cooking.

Question 5

When using a food processor to prepare different types of food, what must be done between batches?

Accepted Answer

Completely disassemble, wash, rinse, and sanitize all parts before processing a different food type

Answer

Food processors have multiple parts that trap food residue and bacteria. Complete disassembly, washing, rinsing, and sanitizing between different food types prevents cross-contamination, especially when switching between raw and ready-to-eat foods.
