ACF - American Culinary Federation Food Safety and Sanitation Questions and Answers

Question 1

According to the FDA Food Code, what is the correct two-stage process for cooling hot foods?

Accepted Answer

From 135°F to 70°F in 2 hours, then to 41°F or lower within an additional 4 hours.

Answer

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?

Accepted Answer

50-100 ppm

Answer

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?

Accepted Answer

Conduct a hazard analysis.

Answer

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?

Accepted Answer

Cross-contamination

Answer

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?

Accepted Answer

41°F to 135°F (5°C to 57°C)

Answer

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.
