At what temperature are frozen items maintained?

Frozen items are typically maintained at a temperature of 0 degrees Fahrenheit or below. This standard ensures that food remains in a frozen state, which is critical for preserving its quality and preventing spoilage. Maintaining frozen items at this temperature helps inhibit the growth of bacteria and other microorganisms that can cause foodborne illnesses.

While the other options mention temperatures that may relate to freezing in some contexts, they do not accurately represent the standard for storage of frozen items. For instance, 32 degrees Fahrenheit is the freezing point of water and marks the transition from liquid to solid but does not guarantee that items remain fully frozen. A temperature of -5 degrees is indeed below freezing and would keep items frozen, but the standard referenced in the question primarily emphasizes the threshold of 0 degrees Fahrenheit for frozen food storage in general practice. The term "below freezing" is somewhat vague and could vary depending on specific contexts, making it less precise than stating the definitive threshold of 0 degrees.
