How long should cooling of potentially hazardous food take?

The correct duration for cooling potentially hazardous food is a maximum of 4 hours. This guideline is essential for food safety because potentially hazardous foods can support the rapid growth of harmful bacteria if they are not cooled properly.

When cooling these foods, it is recommended to do so in two stages: the first stage involves cooling the food from 135°F to 70°F within 2 hours, and the second stage involves cooling it from 70°F to 41°F within the next 4 hours. This ensures that the food passes through the temperature danger zone (between 41°F and 135°F) as quickly as possible, minimizing the risk of bacterial growth.

Observing this cooling time helps maintain food quality and safety, reducing the chances of foodborne illnesses. Not adhering to these guidelines can result in unsafe food conditions, which is why the maximum cooling time is set at 4 hours.
