ACF - American Culinary Federation Food Safety and Sanitation Questions and Answers — Questions and Answers
Question 1: According to the FDA Food Code, what is the correct two-stage process for cooling hot foods?
- From 140°F to 75°F in 3 hours, then to 41°F in 3 hours.
- From 135°F to 70°F in 2 hours, then to 41°F or lower within an additional 4 hours. (Correct answer)
- From 150°F to 80°F in 1 hour, then to 40°F in 5 hours.
- From 130°F to 65°F in 4 hours, then to 41°F in 2 hours.
Correct answer: From 135°F to 70°F in 2 hours, then to 41°F or lower within an additional 4 hours.
The FDA Food Code mandates a two-stage cooling process to minimize the time food spends in the temperature danger zone. The first stage is to cool food from 135°F to 70°F within two hours. The second stage is to cool it from 70°F to 41°F or lower in the next four hours, for a total cooling time of six hours.
Question 2: A chef is setting up a sanitizing station using a chlorine-based solution. What is the acceptable concentration range in parts per million (ppm) for this type of sanitizer on a food-contact surface?
- 25-75 ppm
- 150-400 ppm
- 12.5-25 ppm
- 50-100 ppm (Correct answer)
Correct answer: 50-100 ppm
The FDA-approved concentration for a chlorine (bleach) sanitizer is 50-100 ppm. A concentration that is too low will be ineffective at killing pathogens, while a concentration that is too high can be toxic and leave a harmful residue. Quaternary ammonium compounds are typically used at 150-400 ppm, and iodine at 12.5-25 ppm.
Question 3: Which of the following is the first and most critical step in designing a Hazard Analysis Critical Control Point (HACCP) plan for a foodservice operation?
- Establish monitoring procedures for each CCP.
- Determine Critical Control Points (CCPs).
- Conduct a hazard analysis. (Correct answer)
- Establish corrective actions for deviations.
Correct answer: Conduct a hazard analysis.
The first principle of HACCP is to conduct a thorough hazard analysis. This involves identifying any potential biological, chemical, or physical hazards at all stages of the food production process. Only after identifying the hazards can you then determine where the critical control points (CCPs) are, establish limits, and set up monitoring and corrective actions.
Question 4: A line cook is preparing grilled chicken salads. They use a cutting board to portion raw chicken breasts and then, without cleaning it, begin to chop lettuce for the salad. This is a classic example of which food safety violation?
- Poor personal hygiene
- Time-temperature abuse
- Cross-contamination (Correct answer)
- Improper chemical storage
Correct answer: Cross-contamination
Cross-contamination is the transfer of harmful bacteria or other microorganisms from one food, surface, or piece of equipment to another. Using the same cutting board for raw chicken and then ready-to-eat lettuce without cleaning and sanitizing it in between is a direct violation of cross-contamination prevention principles.
Question 5: The 'Temperature Danger Zone,' as defined by the FDA for foodservice establishments, is the temperature range in which bacteria grow most rapidly. What is this range?
- 32°F to 120°F (0°C to 49°C)
- 41°F to 135°F (5°C to 57°C) (Correct answer)
- 50°F to 150°F (10°C to 66°C)
- 40°F to 140°F (4°C to 60°C)
Correct answer: 41°F to 135°F (5°C to 57°C)
The FDA Food Code specifies the temperature danger zone for retail and foodservice operations as 41°F to 135°F (5°C to 57°C). It is critical to minimize the amount of time Time/Temperature Control for Safety (TCS) foods are held within this range to prevent the rapid multiplication of harmful bacteria.
Question 6: When storing food in a walk-in refrigerator, which of the following demonstrates the correct storage order from top to bottom shelf?
- Raw ground beef, raw fish, ready-to-eat salad, raw chicken
- Raw chicken, raw ground beef, raw fish, ready-to-eat salad
- Ready-to-eat salad, raw fish, raw ground beef, raw chicken (Correct answer)
- Raw fish, ready-to-eat salad, raw chicken, raw ground beef
Correct answer: Ready-to-eat salad, raw fish, raw ground beef, raw chicken
Food should be stored based on the minimum internal cooking temperature of the raw items to prevent cross-contamination. Ready-to-eat foods, which receive no further cooking, must be stored on the top shelf. Raw items are then stored below in order of increasing cooking temperature: raw fish (145°F), raw ground beef (155°F), and raw chicken (165°F) on the bottom to prevent juices from dripping onto and contaminating the items below.
