What is the recommended temperature for a residential refrigerator?

The recommended temperature for a residential refrigerator is between 36-38°F. This temperature range is optimal for keeping food fresh while minimizing the risk of bacterial growth. At these temperatures, most perishable items, like dairy, meats, and produce, maintain their quality and safety. The cold inhibits the growth of harmful bacteria, ensuring that food stays safe for consumption without freezing.

Choosing a temperature within this range strikes a balance between keeping food sufficiently cold and preventing ice formation in the fridge, which can occur at lower temperatures. Maintaining the refrigerator within this range also helps manage energy consumption efficiently, which is another consideration for homeowners.

In contrast, temperatures below this range (like 30-32°F) can risk freezing items, while higher temperatures, such as 40-42°F, do not provide the safety margin needed to prevent spoilage and foodborne illnesses.
