At what temperature should a refrigerator be set to keep food safe?

The recommended temperature for a refrigerator to keep food safe is 38 degrees Fahrenheit. This temperature is optimal for preventing the growth of bacteria that can cause foodborne illnesses. Keeping the temperature at or below this level helps ensure that perishable items, such as meats, dairy products, and leftovers, remain fresh and safe to consume.

At 38 degrees, food is kept cold enough to slow down bacterial growth while not being so cold that it can cause freezing of items closer to the back of the refrigerator. Temperatures higher than this, such as 45 degrees or 50 degrees Fahrenheit, can create conditions that allow bacteria to multiply, increasing the risk of spoilage and foodborne illness.

Maintaining the refrigerator temperature at 38 degrees is a best practice for food safety and helps ensure the longevity and quality of the food stored within.
