What is the recommended air temperature range for a freezer?

The recommended air temperature range for a freezer is typically -20°F to 0°F. This temperature range ensures that food is kept at a safe and consistent level below freezing, which is crucial for preventing the growth of bacteria and preserving the quality of frozen food.

Keeping the freezer at these lower temperatures allows for optimal preservation of perishable items, ensuring texture, flavor, and nutritional value are maintained. It is important to adhere to these guidelines to ensure food safety and compliance with health regulations.

Options that suggest higher temperatures, such as 0°F to 10°F or 20°F to 30°F, do not effectively prevent bacteria growth and can lead to food spoilage. Conversely, while the range of -10°F to 0°F may still be acceptable in many cases, a more ideal range for long-term storage is indeed closer to -20°F, making this temperature necessary for maintaining food safety and integrity over extended periods.
