CPFS Sanitation Standards 4 — Questions and Answers
Question 1: Which method of thawing frozen food is NOT approved by the FDA Food Code for a commercial foodservice operation?
- Thawing under cold running water at 70°F or below
- Thawing in a microwave as part of the cooking process
- Thawing at room temperature on a prep counter overnight (Correct answer)
- Thawing in a refrigerator at 41°F or below
Correct answer: Thawing at room temperature on a prep counter overnight
Thawing at room temperature allows the outer layers of food to enter the temperature danger zone while the interior remains frozen.
Question 2: A food manager discovers a shipment of canned goods with several severely dented cans along the seam. What is the correct action?
- Use the dented cans first and inspect contents before serving
- Accept the shipment but keep dented cans separate from others
- Refuse the delivery and return dented cans to the supplier (Correct answer)
- Discard only cans with visible rust or leaks
Correct answer: Refuse the delivery and return dented cans to the supplier
Cans with seam dents must be refused because seam damage can allow microorganisms, including Clostridium botulinum, to enter.
Question 3: What is the purpose of a master cleaning schedule in a foodservice operation?
- To schedule employee breaks and shift rotations
- To assign, time, and document all sanitation tasks systematically (Correct answer)
- To track food inventory levels and purchasing cycles
- To record temperature logs for refrigeration equipment
Correct answer: To assign, time, and document all sanitation tasks systematically
A master cleaning schedule specifies who cleans what, how often, and with which products, ensuring all sanitation tasks are completed consistently.
Question 4: Which of the following describes the 'two-stage cooling' method required by the FDA Food Code?
- Cool from 165°F to 70°F within 4 hours, then to 41°F within 2 hours
- Cool from 135°F to 70°F within 2 hours, then to 41°F within 4 hours (Correct answer)
- Cool from 135°F to 41°F within 4 hours total
- Cool from 165°F to 41°F within 6 hours using any method
Correct answer: Cool from 135°F to 70°F within 2 hours, then to 41°F within 4 hours
The FDA Food Code requires cooling TCS foods from 135°F to 70°F within 2 hours, and then from 70°F to 41°F within the next 4 hours.
Question 5: What is the minimum distance food must be stored off the floor in a foodservice establishment?
- 3 inches (7.6 cm)
- 6 inches (15 cm) (Correct answer)
- 8 inches (20 cm)
- 12 inches (30 cm)
Correct answer: 6 inches (15 cm)
FDA Food Code requires food to be stored at least 6 inches off the floor to prevent contamination and allow for cleaning beneath storage units.
Question 6: Which chemical sanitizer remains effective over the widest range of pH levels in foodservice operations?
- Chlorine (sodium hypochlorite)
- Iodine (iodophor)
- Quaternary ammonium compounds (quats) (Correct answer)
- Hydrogen peroxide
Correct answer: Quaternary ammonium compounds (quats)
Quaternary ammonium compounds are effective across a broader pH range than chlorine or iodine and are less affected by water hardness.
Question 7: In a foodservice operation, what does the term 'clean-in-place' (CIP) refer to?
- Cleaning food contact surfaces without moving or disassembling equipment (Correct answer)
- Mopping the floor around stationary equipment
- Wiping down exterior surfaces of refrigeration units in place
- Disinfecting walls and ceilings without removing ceiling tiles
Correct answer: Cleaning food contact surfaces without moving or disassembling equipment
CIP systems clean the interior surfaces of equipment like piping and tanks by circulating cleaning solutions through them without disassembly.
