What temperature should perishable food ideally be stored at?

Perishable food should ideally be stored at temperatures between 30°F and 40°F to slow the growth of bacteria and maintain food safety. This temperature range is considered the "refrigeration zone," where the activity of microorganisms is significantly reduced, thereby extending the shelf life of food products.

Storing perishable food below 30°F is typically used for freezing, which is appropriate for long-term storage but not ideal for foods that need to be kept at a temperature where they can still be used fresh. Conversely, temperatures above 50°F encourage bacterial proliferation, increasing the risk of foodborne illnesses. Room temperature is not suitable for the safe storage of perishable items, as it often falls within the "danger zone" (40°F to 140°F), where bacteria can thrive. Hence, the recommended storage temperature range maximizes food safety and quality.
