What temperature is a fridge and freezer?

The temperature of a refrigerator should be 40 degrees Fahrenheit or below, while the freezer temperature should be 0 degrees Fahrenheit, according to the U.S. Food and Drug Administration. Placing a freestanding appliance thermometer inside the fridge and freezer permits easy monitoring of temperatures.

Keeping the fridge and freezer at the optimal temperatures reduces the possibility that bacteria grows on food and makes it unsafe to eat. To keep foods properly cooled, air must be able to circulate around each item freely. Wiping up any spills immediately in both fridge and freezer also helps to prevent the growth of bacteria and contamination of foods.
