ideal freezer temperature usda
The United States Food and Drug Administration (FDA) mandates that refrigerated products must be kept at 41 Degrees Fahrenheit or lower. But the colder the food is the longer it will last, making 38F an ideal temperature for commercial refrigeration. Freezer temperature ranges are generally much colder. Some foods are more sensitive to cold temperatures than others, so the type of food you are storing as well as the type of refrigeration unit you are using will also affect the temperature you need to set.
