What is the recommended maximum temperature for refrigerated storage of perishables?

The recommended maximum temperature for refrigerated storage of perishables is 40°F. This temperature is critical because it helps inhibit the growth of bacteria, which can proliferate at higher temperatures, leading to foodborne illnesses. Storing perishables at or below 40°F ensures that they remain safe for consumption for a longer period of time while preserving their freshness and quality.

To maintain food safety, it is essential to keep the internal temperature of refrigerators at or below this threshold. When food items are kept at temperatures above 40°F, especially in the range of 41°F to 135°F, they enter the "danger zone," where harmful bacteria can multiply rapidly.

While freezing temperatures, such as 0°F or lower, are suitable for long-term storage of certain foods, they are not appropriate for perishable items that need to be kept fresh for daily use. Temperatures around 32°F are close to freezing but may not be optimal for all perishables, as they can cause some items, like fruits and vegetables, to sustain damage or lose their quality. Therefore, 40°F acts as a balanced point that maximizes safety without compromising product quality.
