Sample Practice Questions for Preventing Cross-Contamination & Allergens

1. Question 1Ref: FDA Food Code 2022 — §3-302.11

   In a walk-in cooler, where should raw chicken be stored relative to other foods?

   AOn the bottom shelf below all other foodsBOn the same shelf as ready-to-eat foodsCOn the top shelf above produceDIn any available space regardless of shelf
   Show Answer & Explanation

   Correct Answer
   A. On the bottom shelf below all other foods

   The keyed answer is "On the bottom shelf below all other foods". Raw poultry must be stored on the bottom shelf because it requires the highest cooking temperature (165°F). This prevents raw juices from dripping onto foods requiring less cooking or ready-to-eat foods, preventing cross-contamination.

2. Question 2Ref: FDA Food Code 2022 — §4-501.110

   What is the correct order of steps when using a three-compartment sink?

   ASanitize, wash, rinseBWash, sanitize, rinseCWash, rinse, sanitizeDRinse, wash, sanitize
   Show Answer & Explanation

   Correct Answer
   C. Wash, rinse, sanitize

   The keyed answer is "Wash, rinse, sanitize". The correct sequence is wash (first compartment, 110°F with detergent), rinse (second compartment, clean warm water), then sanitize (third compartment with chemical sanitizer or 171°F hot water). Skipping or reordering any step reduces effectiveness.

3. Question 3Ref: FDA Food Code 2022 — §3-603.11

   What is the primary way to prevent cross-contact with food allergens during preparation?

   AUse clean, sanitized equipment and wash hands between tasksBCook allergen-free foods at higher temperaturesCAdd more seasoning to mask allergen flavorsDServe allergen-free foods on smaller plates
   Show Answer & Explanation

   Correct Answer
   A. Use clean, sanitized equipment and wash hands between tasks

   The keyed answer is "Use clean, sanitized equipment and wash hands between tasks". Cross-contact is prevented by washing hands, using clean sanitized equipment, and using separate utensils and cooking surfaces. The Big 9 allergens must never come into contact with allergen-free foods through shared equipment or improper handling.

4. Question 4Ref: FDA Food Code 2022 — §4-501.110

   What is the required water temperature for the wash step in a three-compartment sink?

   A75°F (24°C) or warmerB100°F (38°C) or warmerC110°F (43°C) or warmerD171°F (77°C) or warmer
   Show Answer & Explanation

   Correct Answer
   C. 110°F (43°C) or warmer

   The keyed answer is "110°F (43°C) or warmer". The wash compartment must have water at 110°F (43°C) or warmer with commercial dishwashing detergent. This effectively removes grease and food debris. The sanitizer compartment requires 75°F minimum for chemicals or 171°F for hot water sanitizing.
