  1. What is the first stage of the two-stage cooling process for Time/Temperature Control for Safety (TCS) foods?

    Answer: Cool food from 135°F to 70°F within 2 hours.

    The first stage requires rapid cooling through the most dangerous part of the temperature danger zone. Food must be cooled from 135°F (57°C) to 70°F (21°C) within 2 hours.

  2. What is the maximum total time allowed for the entire two-stage cooling process?

    Answer: 6 hours

    The total cooling time from 135°F (57°C) to 41°F (5°C) must not exceed 6 hours. This is composed of the first 2-hour stage and the second 4-hour stage.

  3. During the second stage of the cooling process, food must be cooled from 70°F down to what temperature?

    Answer: 41°F or lower

    The second stage involves cooling the food from 70°F (21°C) down to 41°F (5°C) or lower to ensure it is safe for cold storage.

  4. What is the maximum time allowed for the second stage of the two-stage cooling process?

    Answer: 4 hours

    After cooling food to 70°F within the first 2 hours, you have an additional 4 hours to cool it down to 41°F or lower, for a total of 6 hours.

  5. If you cool a large pot of chili from 135°F to 70°F in 1 hour, how much time do you have left to cool it to 41°F?

    Answer: 5 hours

    The total cooling time must be 6 hours or less. If the first stage (135°F to 70°F) is completed in 1 hour (instead of the maximum 2), the remaining time for the second stage (70°F to 41°F) is 5 hours.

  6. Which of the following is an approved method for cooling food rapidly?

    Answer: Using an ice-water bath and stirring the food.

    Methods like ice-water baths, ice paddles, and dividing food into smaller, shallow containers are effective for rapid cooling. Placing a large, hot pot in a cooler can raise the ambient temperature, endangering other foods.

  7. What must be done if a TCS food has not been cooled to 70°F within 2 hours?

    Answer: Reheat the food to 165°F for 15 seconds and start the cooling process again.

    If the first stage of cooling is not met, the food has been in the temperature danger zone for too long. It must be reheated to 165°F for 15 seconds to kill any bacteria that may have grown, and then the cooling process must be restarted.
