What temperature should a refrigerator be maintained at?

The optimal temperature range for a refrigerator is between 32°F to 40°F (0°C to 4°C). This specific range is crucial for the safe storage of food, as it effectively slows down the growth of harmful bacteria that can cause foodborne illnesses. Keeping the refrigerator within this range ensures that perishable foods, such as meats, dairy products, and other items, remain fresh and safe for consumption.

While a temperature of 30°F to 36°F (−1°C to 2°C) might seem adequate, it could pose a risk of freezing some items, particularly those with a higher water content. On the other hand, temperatures exceeding 40°F (4°C) are known to encourage bacteria growth, which can lead to food spoilage and health risks. Maintaining temperatures below 25°F (−4°C to −1°C) would not be suitable either, as this would cause food to freeze, negatively impacting texture and quality. Thus, the recommended range strikes a balance between safety and food preservation, making it the ideal temperature to maintain in a refrigerator.
