The recommended temperature range for a refrigerator to keep food safe is between 32°F to 40°F. This range is critical as it helps inhibit the growth of harmful bacteria that can cause foodborne illnesses. Keeping the temperature at or below 40°F slows down the deterioration of food while ensuring that perishables such as meat, dairy, and produce remain fresh for a longer duration.

When food is stored outside this range, particularly above 40°F, the risk of bacterial growth increases significantly. For instance, temperatures above this threshold can encourage the proliferation of pathogens that thrive in warmer environments. Conversely, temperatures at or below 32°F can lead to freezing, which may compromise the texture and quality of certain foods, but still keep them safe.

Understanding and maintaining the right temperature helps in ensuring food safety, preserving food quality, and minimizing waste. Thus, the selected temperature range is established by food safety guidelines to protect public health.
