CFSP Food Safety Management 4 — Questions and Answers
Question 1: In a foodservice operation, cross-contamination from raw proteins to ready-to-eat foods is BEST prevented by:
- Using color-coded cutting boards and utensils designated by food type (Correct answer)
- Washing all foods with soap before preparation
- Storing all proteins together in one refrigerator section
- Cooking proteins before storing them with other foods
Correct answer: Using color-coded cutting boards and utensils designated by food type
Color-coded equipment creates a physical and procedural barrier that prevents raw proteins from contacting ready-to-eat items.
Question 2: A toxin produced by Staphylococcus aureus is particularly dangerous in foodservice because:
- It requires a large dose to cause illness
- It is destroyed by normal cooking temperatures
- It is heat-stable and cannot be destroyed by reheating (Correct answer)
- It only affects immunocompromised individuals
Correct answer: It is heat-stable and cannot be destroyed by reheating
Staphylococcal enterotoxins are heat-stable proteins that remain active even after the bacteria that produced them have been killed by cooking.
Question 3: Which practice best demonstrates the principle of Active Managerial Control in a foodservice operation?
- Posting food safety posters in the kitchen
- Scheduling health inspections quarterly
- Conducting daily pre-shift foodhandler briefings and temperature checks (Correct answer)
- Requiring employees to read the employee handbook annually
Correct answer: Conducting daily pre-shift foodhandler briefings and temperature checks
Active Managerial Control involves ongoing, day-to-day oversight by managers who actively intervene to prevent foodborne illness risk factors.
Question 4: When thawing frozen ground beef under refrigeration, the maximum safe thawing temperature is:
- 32°F
- 41°F (Correct answer)
- 45°F
- 50°F
Correct answer: 41°F
Refrigerator thawing must occur at 41°F or below to keep the outer surface of the product out of the temperature danger zone.
Question 5: Which type of thermometer is MOST appropriate for measuring the surface temperature of a flat grill or griddle?
- Bimetallic stemmed thermometer
- Thermocouple with surface probe
- Infrared thermometer aimed at the surface (Correct answer)
- Digital pocket thermometer
Correct answer: Infrared thermometer aimed at the surface
Infrared thermometers measure surface temperature without contact, making them ideal for checking hot cooking surfaces like griddles.
Question 6: A food safety audit reveals that employees are not washing hands between handling raw chicken and preparing salads. Under HACCP, this gap would be addressed during which principle?
- Principle 1 – Hazard Analysis
- Principle 4 – Monitoring
- Principle 5 – Corrective Actions
- Principle 6 – Verification (Correct answer)
Correct answer: Principle 6 – Verification
Verification activities, including audits and observations, confirm that the HACCP system is working effectively and employees are following established procedures.
Question 7: The FDA recommends that highly susceptible populations (HSP) should NOT be served which of the following?
- Well-done hamburgers
- Pasteurized orange juice
- Raw or undercooked eggs (Correct answer)
- Commercially canned tuna
Correct answer: Raw or undercooked eggs
Raw or undercooked eggs pose a Salmonella risk that is especially dangerous for highly susceptible populations such as elderly, pregnant, or immunocompromised individuals.
