What is the recommended storage temperature for frozen foods?

The recommended storage temperature for frozen foods is ideally at or below 0 degrees Fahrenheit. This ensures that the food remains safely frozen and helps to maintain its quality, texture, and flavor over time. Storing food at temperatures above 0 degrees can lead to partial thawing, which can promote bacterial growth and spoilage.

While other options may seem plausible, they do not provide the optimal range for long-term frozen food preservation. For instance, -5 to -15 degrees and -10 to -20 degrees are indeed below 0 and are acceptable for maintaining food in a frozen state, but they can be too cold for some types of freezers or may not be necessary for standard household storage. The range of 32 to 0 degrees is not suitable for frozen foods, as 32 degrees represents the freezing point of water, where food would not remain solidly frozen. Thus, the first answer accurately reflects the standard practice for effectively safeguarding frozen foods.
