What is the ideal temperature range for storing perishable foods in a refrigerator?

The ideal temperature range for storing perishable foods in a refrigerator is between 32°F and 39°F. This range is important because it helps to slow the growth of bacteria and other pathogens that can cause foodborne illnesses. Keeping food at these temperatures ensures freshness while maintaining safety, as temperatures above 40°F can start to allow bacteria to multiply rapidly.

This range is optimal for most perishable items including meats, dairy products, and certain fruits and vegetables. When food is stored below 32°F, it risks freezing, which can alter texture and quality, rendering some foods undesirable for consumption. Additionally, temperatures above 39°F are less effective in preventing the growth of harmful microorganisms, potentially leading to spoilage and food safety issues. Therefore, maintaining a refrigerator temperature within the 32°F to 39°F range is crucial for food safety.
