What is the ideal indoor temperature range for a standard residential refrigerator setting?

The ideal indoor temperature range for a standard residential refrigerator setting is between 36-38°F. This range is crucial for preserving food safely while maximizing freshness. At temperatures in this range, most bacteria that can spoil food thrive less effectively, thereby extending the food's shelf life and maintaining the safety of perishable items.

Keeping the refrigerator at this temperature ensures that items like dairy, meat, and produce are stored at temperatures that slow down bacterial growth and maintain quality. It's also warm enough to prevent freezing the items located near the back of the fridge, which can occur at lower temperatures.

Maintaining a temperature of 36-38°F strikes a balance between food safety, preventing spoilage, and ensuring energy efficiency, making it the most recommended range for optimal refrigerator performance.
