Question

which temperature should a freezer be set at to maintain food safety? at 0°f, below 0°f but no lower than -10°f, between 0°f and 32°f, above 32°f

Explanation:

Food safety in freezers is maintained when the temperature is low enough to inhibit bacterial growth and keep food frozen. Temperatures above 32°F (the freezing - point of water) will cause food to thaw, and temperatures at or above 0°F may not keep food frozen solidly enough for long - term safety. A temperature below 0°F but not lower than - 10°F helps ensure food remains frozen and safe.

Answer:

D. below 0°F but no lower than - 10°F
