Which of the following is a requirement for the refrigerator temperature range?

The requirement for the refrigerator temperature range being between 35°F and 46°F is critical for ensuring food safety and proper storage of perishable items. This temperature range helps to inhibit bacterial growth while preserving the quality and freshness of food.

Temperature below 32°F could cause freezing, which may damage certain food items and alter their texture and taste negatively. Additionally, maintaining a temperature at least 50°F is far too high for safe storage of perishables, as it significantly increases the risk of foodborne illnesses. Keeping temperatures above 40°F may still be unsafe, especially if they rise significantly, as this can allow harmful bacteria to grow.

Therefore, the specified range of 35°F to 46°F is the industry standard for refrigerator temperatures to ensure optimal food safety and quality.
