What is the recommended temperature setting for refrigerators?

The recommended temperature setting for refrigerators is typically between 37-40°F. This range is optimal for food safety and freshness; it is cool enough to prevent the growth of harmful bacteria while still allowing for the preservation of perishable items. Maintaining the refrigerator at this temperature helps ensure that food stays fresh and safe for consumption, maximizing both safety and shelf life.

Temperatures lower than this range can cause food to freeze, leading to texture and flavor degradation in items that are not intended to be frozen. Conversely, temperatures above this range can increase the risk of bacterial growth, making food unsafe. Therefore, the 37-40°F range strikes a balance between maintaining food quality and ensuring safety.
