Which of the following temperatures is recommended for a home freezer?

• A. 10°F
• B. -5°F
• C. 0°F
• D. -10°F

Answer: (B)

The recommended temperature for a home freezer is 0°F. This temperature ensures that food is kept adequately frozen, which is crucial for maintaining its quality and preventing spoilage. At 0°F, food will remain in a solid state, and the growth of microorganisms is significantly slowed down, thus preserving both safety and nutritional value. Keeping a freezer at 0°F allows for optimal energy efficiency as well. Temperatures that are lower, such as -5°F or -10°F, although they will freeze food solidly, can cause an increase in energy consumption without substantial benefits for most home food storage needs. Conversely, a setting of 10°F is above the recommended freezing point and can lead to potential food safety issues, as it might allow for the growth of bacteria and cause food degradation. Thus, 0°F strikes the best balance between food preservation, safety, and energy efficiency for home freezers.
