Recognize the controlling condition
Cooling removes heat while the food passes through conditions that may permit growth. Container depth, airflow, batch size, and mixing affect cooling progress. Reheating for hot holding is a later process with its own endpoint and time requirement. The model requires cooling from 135 F to 70 F within two hours, then to 41 F within six total hours. The second stage is governed by six total hours from 135 F, not an independent new six-hour period. Increasing heat transfer and checking the actual food help meet cooling limits. Reheating for hot holding has its own treatment and time limit, distinct from the later holding minimum.
Work a decision from its evidence
Under the 2022 model, cooked soup cools from 135 F to 80 F in the first two hours. The appropriate response is to apply the approved first-stage cooling corrective procedure. The decisive reason is: The model requires cooling from 135 F to 70 F within two hours, then to 41 F within six total hours. Compare the tempting alternative "Count it as compliant because it is below 100 F.". Being below an arbitrary round temperature does not meet the first-stage limit. Before choosing, identify the specific condition that makes this rule applicable. Do not transfer a number, exception, or permission to a different situation without checking its conditions.
Contrast a different mistake
Cooked soup starts cooling at 135 F, reaches 70 F after two hours, and reaches 41 F after another three hours under the 2022 model cooling process. Here the appropriate response is: Accept the recorded two-stage cooling as compliant. A different proposed response is "Restart a new six-hour allowance at 70 F.". A fresh six-hour allowance would improperly extend the total process. The difference between these cases is the source of the risk or obligation, not a change in the decision maker's preference. Explain the distinction before reading the answer to the linked example.
Apply and check the method
Draw the cooling timeline from its original start. Mark the first-stage endpoint and the total elapsed limit; moving the food or changing its container does not restart the clock. Select a practical heat-transfer improvement before assuming a cooler will correct every large batch. For cooling first stage, ask whether the proposed response addresses this condition: The model requires cooling from 135 F to 70 F within two hours, then to 41 F within six total hours. For cooling second stage, ask whether the proposed response addresses this condition: The second stage is governed by six total hours from 135 F, not an independent new six-hour period. For cooling methods, ask whether the proposed response addresses this condition: Increasing heat transfer and checking the actual food help meet cooling limits. For reheating for hot holding, ask whether the proposed response addresses this condition: Reheating for hot holding has its own treatment and time limit, distinct from the later holding minimum. Check the explanation against the cited reference, then answer the associated case items without using the option length or answer position as a clue.
Under the 2022 model, cooked soup cools from 135 F to 80 F in the first two hours. What is the most appropriate response?
- Identify the controlling condition: Cooling first stage.
- The model requires cooling from 135 F to 70 F within two hours, then to 41 F within six total hours.
- Apply it: Apply the approved first-stage cooling corrective procedure.
- Compare the alternative "Count it as compliant because it is below 100 F.": Being below an arbitrary round temperature does not meet the first-stage limit.
Compare the other answer choices
Being below an arbitrary round temperature does not meet the first-stage limit.
The additional cooling period is not an extension of the first-stage deadline.
Moving containers does not reset elapsed cooling time.
