When the food is cooled outside the refrigerator using the ice bath, then the temperature of the food reaches 140⁰F (60⁰C) within the two hours and 70⁰F with in a total of 6 hours.

Further explanation:

When we cook a dish, or a soup and we are planning to store it then we should not put it in the refrigerator or in a freezer immediately. If the food is immediately put in the freezer then the risk of contracting a food borne illness increases.

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.

Use water bath to cool down the food:

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.
