What is the benefit of maintaining a proper refrigerator temperature?

Maintaining a proper refrigerator temperature is crucial because it significantly slows down the growth of harmful bacteria that can cause foodborne illnesses. Bacteria thrive in certain temperature ranges, particularly between 41°F and 135°F, often referred to as the "danger zone." By keeping refrigerator temperatures at or below 40°F, the growth rate of these bacteria is dramatically reduced, thereby extending the shelf life of perishable foods and ensuring they remain safe for consumption.

While maintaining appropriate temperatures may also have positive effects on food presentation, taste, and even costs indirectly by reducing waste, the primary and most critical benefit is the prevention of bacterial growth, which directly impacts food safety. Keeping food at the correct temperature is a fundamental practice in food protection, prioritizing public health above all.
