HACCP Temperature Control & Food Safety 1 — Questions and Answers
Question 1: What is the temperature danger zone for food safety according to FDA guidelines?
- 32°F to 70°F (0°C to 21°C)
- 40°F to 140°F (4°C to 60°C) (Correct answer)
- 50°F to 165°F (10°C to 74°C)
- 41°F to 165°F (5°C to 74°C)
Correct answer: 40°F to 140°F (4°C to 60°C)
The FDA defines the temperature danger zone as 40°F to 140°F (4°C to 60°C), where bacteria multiply most rapidly.
Question 2: What is the minimum safe internal cooking temperature for whole poultry according to USDA guidelines?
- 145°F (63°C)
- 155°F (68°C)
- 165°F (74°C) (Correct answer)
- 170°F (77°C)
Correct answer: 165°F (74°C)
The USDA requires whole poultry to reach 165°F (74°C) internally to destroy Salmonella and other pathogens.
Question 3: How long can potentially hazardous food remain in the temperature danger zone before it must be discarded?
- 2 hours cumulative
- 4 hours cumulative (Correct answer)
- 6 hours cumulative
- 8 hours cumulative
Correct answer: 4 hours cumulative
Food must be discarded if it has spent a cumulative total of 4 or more hours in the temperature danger zone (40°F–140°F).
Question 4: What is the maximum acceptable temperature for receiving cold potentially hazardous foods?
- 32°F (0°C)
- 41°F (5°C) (Correct answer)
- 45°F (7°C)
- 50°F (10°C)
Correct answer: 41°F (5°C)
Cold potentially hazardous foods must be received at 41°F (5°C) or below to confirm proper refrigeration during transport.
Question 5: What is the minimum internal cooking temperature for ground beef patties?
- 145°F (63°C)
- 155°F (68°C)
- 160°F (71°C) (Correct answer)
- 165°F (74°C)
Correct answer: 160°F (71°C)
Ground beef must reach 160°F (71°C) because grinding distributes surface pathogens like E. coli O157:H7 throughout the meat.
Question 6: What does the first stage of the two-stage cooling method require?
- Cool from 165°F to 70°F within 4 hours
- Cool from 135°F to 70°F within 2 hours (Correct answer)
- Cool from 140°F to 41°F within 4 hours
- Cool from 165°F to 41°F within 2 hours
Correct answer: Cool from 135°F to 70°F within 2 hours
The first stage requires cooling food from 135°F to 70°F within 2 hours to pass quickly through the most dangerous temperature range.
Question 7: What minimum temperature must hot foods be maintained at during food service to prevent bacterial growth?
- 120°F (49°C)
- 130°F (54°C)
- 135°F (57°C) (Correct answer)
- 140°F (60°C)
Correct answer: 135°F (57°C)
The FDA Food Code requires hot foods to be held at 135°F (57°C) or above during service to keep them above the temperature danger zone.
