Danger zone of food:
The danger zone for food is from 140⁰F (60⁰C) to 40⁰F (4⁰C). The cooked food should not remain in the danger zone for more than two hours. Because when the food reaches this zone, then they provide optimum conditions for the growth of bacteria and other toxins that lead to various diseases. We should not cool the food at room temperature.

In order to cool the food evenly and rapidly, we should keep the food container in the ice bath. It is a simple process. Simply fill a large bowl with the ice and cold water. Now place the food in the water bath. Stir the food every 15 to 20 minutes to evenly distribute the heat into the cold areas. In this way the food is cooled down evenly. Monitor food with the help of the thermometer.
