How long must bagged products be cooled to 34°F?

1. 24 hours

2. 48 hours

3. 72 hours

4. 30 days

The correct answer is: 48 hours

The requirement to cool bagged products to 34°F is based on food safety standards that are set to prevent the growth of harmful bacteria and ensure food is stored safely. Cooling food to a specific temperature must be done within a designated time frame to minimize the risk of foodborne illness. According to food safety guidelines, bagged products should be cooled properly and efficiently to prevent bacteria from thriving in the temperature danger zone, which typically ranges from 41°F to 135°F. Cooling to 34°F within a timeframe of 48 hours ensures that the food remains safe for consumption while maintaining its quality. This period allows sufficient time for larger amounts of food to reach safe temperatures without compromising the safety or integrity of the product. The other timeframes listed, such as 24 hours, 72 hours, and 30 days, either do not allow for adequate cooling and risk unsafe temperatures or extend beyond what is typically considered safe for shelf life and bacterial growth prevention. For instance, a 72-hour cooling period is excessive, suggesting a duration that exceeds typical food safety practices.
