CRP Quality Standards & Compliance 3 — Questions and Answers
Question 1: What is the correct procedure for cooling a large pot of soup from 135°F to safe storage temperature?
- Leave on counter until room temperature, then refrigerate
- Cool from 135°F to 70°F within 2 hours, then to 41°F within 4 more hours (Correct answer)
- Refrigerate directly in the large pot with lid on
- Cool in freezer for 30 minutes then move to refrigerator
Correct answer: Cool from 135°F to 70°F within 2 hours, then to 41°F within 4 more hours
The two-stage cooling method requires reducing temperature from 135°F to 70°F within 2 hours, then to 41°F within the next 4 hours to prevent pathogen growth.
Question 2: Which hand hygiene step is most critical after using the restroom before returning to food preparation?
- Applying hand sanitizer at the prep station
- Washing hands with soap and warm water for at least 20 seconds (Correct answer)
- Wearing gloves immediately upon re-entering the kitchen
- Rinsing hands with cold water
Correct answer: Washing hands with soap and warm water for at least 20 seconds
Proper handwashing with soap and warm water for a minimum of 20 seconds is required after using the restroom and is more effective than sanitizer alone for removing pathogens.
Question 3: A health inspector cites a restaurant for 'bare-hand contact with ready-to-eat food.' Which corrective action is required?
- Purchase additional gloves and store near prep areas
- Implement a policy requiring utensils, deli tissue, or gloves when handling RTE foods (Correct answer)
- Train staff to wash hands more frequently
- Limit RTE food items on the menu
Correct answer: Implement a policy requiring utensils, deli tissue, or gloves when handling RTE foods
Bare-hand contact with RTE foods is prohibited; establishments must use utensils, deli tissue, or single-use gloves, and must document an approved alternative bare-hand contact procedure if sought.
Question 4: What does the term 'critical limit' mean in a HACCP plan?
- The maximum number of menu items allowed per service
- The minimum or maximum value at a CCP that prevents, eliminates, or reduces a hazard to an acceptable level (Correct answer)
- The threshold at which a restaurant must close for cleaning
- The number of food safety violations before license revocation
Correct answer: The minimum or maximum value at a CCP that prevents, eliminates, or reduces a hazard to an acceptable level
A critical limit is the scientifically established boundary at a Critical Control Point that separates acceptable from unacceptable conditions for food safety.
Question 5: Which sanitizer concentration is acceptable for chlorine-based sanitizers used on food-contact surfaces?
- 10–25 ppm
- 50–100 ppm (Correct answer)
- 200–300 ppm
- 400 ppm or higher
Correct answer: 50–100 ppm
Chlorine-based sanitizers for food-contact surfaces should be maintained at 50–100 ppm to be effective without leaving harmful residues.
Question 6: An employee working the grill is observed touching raw chicken and then handling cooked burger buns without changing gloves. This is an example of:
- Time-temperature abuse
- Cross-contamination (Correct answer)
- Improper cooling
- Inadequate pest control
Correct answer: Cross-contamination
Handling raw poultry and then touching ready-to-eat items without changing gloves or washing hands is a direct example of cross-contamination.
Question 7: What is the required minimum air gap between a potable water supply outlet and the flood level rim of a sink used for food preparation?
- ½ inch
- 1 inch
- 2 times the inside diameter of the supply pipe (Correct answer)
- Equal to the diameter of the drain pipe
Correct answer: 2 times the inside diameter of the supply pipe
Plumbing codes require an air gap of at least two times the inside diameter of the supply pipe to prevent back-siphonage and cross-connection with wastewater.
