Questions with Answers and Detailed Rationales
1. What is the correct minimum internal cooking temperature for
poultry?
Answer: 165°F (74°C) for 15 seconds
Rationale: Poultry requires the highest cooking temperature because it
is highly susceptible to pathogens like Salmonella and
Campylobacter. The temperature must be reached throughout the
food.
2. What is the danger zone temperature range?
Answer: 41°F to 135°F (5°C to 57°C)
Rationale: Bacteria grow rapidly within this range, doubling in
number in as little as 20 minutes.
3. How long can TCS food safely remain in the danger zone?
Answer: 4 hours maximum
Rationale: After 4 hours, bacteria growth may reach unsafe levels and
food must be discarded.
4. What is the correct handwashing duration?
Answer: At least 20 seconds
Rationale: Proper handwashing removes pathogens effectively when
done with soap, friction, and time.
, 5. What temperature should a refrigerator be set at?
Answer: 41°F (5°C) or lower
Rationale: This slows bacterial growth in potentially hazardous foods.
6. What is the correct minimum internal temperature for ground
beef?
Answer: 155°F (68°C) for 15 seconds
Rationale: Grinding spreads bacteria throughout the meat, requiring
higher cooking temperatures than whole cuts.
7. What is cross-contamination?
Answer: Transfer of harmful microorganisms from one food or
surface to another
Rationale: Usually occurs when raw food touches ready-to-eat food or
unclean equipment.
8. What is the correct hot holding temperature?
Answer: 135°F (57°C) or higher
Rationale: Keeps food out of the danger zone and prevents bacterial
growth.
9. What should a food handler do if they have diarrhea and
vomiting?
Answer: Exclude themselves from work
, Rationale: These symptoms indicate highly contagious illness that can
spread to customers.
10. What is FIFO in food storage?
Answer: First In, First Out
Rationale: Ensures older stock is used before newer stock to prevent
spoilage and waste.
11. What is the minimum internal temperature for seafood?
Answer: 145°F (63°C) for 15 seconds
Rationale: Seafood must be properly cooked to eliminate parasites
and bacteria.
12. What is the purpose of sanitizing?
Answer: To reduce pathogens to safe levels
Rationale: Cleaning removes dirt; sanitizing reduces microbes.
13. What is a foodborne illness?
Answer: Illness caused by consuming contaminated food or drink
Rationale: Often caused by bacteria, viruses, parasites, or toxins.
14. What is the correct cooling procedure for hot food?
Answer: 135°F to 70°F within 2 hours, then to 41°F within 4 more
hours
Rationale: Rapid cooling prevents bacterial growth.
