Question: 1 / 400

What temperature should a refrigerator be maintained at for safe food storage?

40°F (4°C) or lower

Maintaining a refrigerator temperature at 40°F (4°C) or lower is crucial for safe food storage as it helps to inhibit the growth of harmful bacteria. Bacteria can multiply rapidly at temperatures above 40°F, increasing the risk of foodborne illnesses. Keeping food refrigerated at or below this temperature slows down bacterial growth and preserves the freshness and safety of perishable items such as meat, dairy, and certain produce.

The other temperature options do not provide a safe environment for food storage. For instance, a temperature of 35°F (1.7°C) is also safe but is colder than necessary. Higher temperatures, such as 45°F (7°C) or 50°F (10°C), significantly increase the risk of bacterial growth, making food unsafe for consumption. Thus, ensuring your refrigerator operates at 40°F (4°C) or lower is a standard guideline for maintaining food safety.
