What is the ideal refrigerator temperature for food safety?

The ideal refrigerator temperature for food safety is between 34°F to 40°F (1°C to 4°C). Maintaining this temperature range is crucial because it slows the growth of harmful bacteria that can cause foodborne illnesses. When food is stored at temperatures above this range, particularly above 40°F, the risk of bacteria multiplying increases significantly. Keeping the refrigerator within this recommended range ensures that perishable items, such as meat, dairy, and leftovers, remain safe for consumption while also preserving their quality.

In contrast, temperatures below 34°F may lead to freezing, which can affect the texture and flavor of many foods, and temperatures above 40°F create an environment conducive to bacterial growth. Thus, the range of 34°F to 40°F is optimal for food safety and quality.
