At which temperature should you set your freezer at to maintain food safety:

The ideal freezer temperature is 0 Fahrenheit (-18 Celsius) for storing food. And -10 Fahrenheit (-23 Celsius) is recommended when freezing food.

For every five degrees Fahrenheit above zero, the recommended storage time is cut in half. Food stored above 0 Fahrenheit loses more nutrients and loses quality faster than properly frozen food.
