What is the effective cooling time frame for TCS foods from 135 degrees F to 70 degrees F?

1. 2 hours

2. 1 hour

3. 4 hours

4. 5 hours

The correct answer is: 2 hours

The effective cooling time frame for Time/Temperature Control for Safety (TCS) foods to move from 135 degrees F to 70 degrees F is indeed 2 hours. This timeframe is in accordance with food safety guidelines designed to minimize the risk of bacterial growth during the cooling process. When food is prepared, it needs to pass through the temperature danger zone (between 41 degrees F and 135 degrees F) quickly to prevent harmful bacteria from multiplying. The two-hour window allows for sufficient time to cool the food from 135 degrees F, where it is still very warm, down to 70 degrees F before it must go below 41 degrees F within an additional four hours, thereby completing the cooling process in no more than a total of six hours. This guideline helps ensure that TCS foods are cooled effectively, reducing the risk of foodborne illness. Options such as 1 hour would not provide enough time for safe cooling, while 4 hours or 5 hours would exceed the recommended timeframe, potentially allowing for unsafe bacterial growth.
