The ideal temperature for a refrigerator is 35-38°F (1.6-3.3°C), according to most experts. The U.S. Food and Drug Administration (FDA) also recommends that the refrigerator temperature should be at or below 40°F (4.4°C) . This temperature range inhibits the growth of bacteria that can cause foodborne illnesses, such as salmonella, listeria, and E. coli. It is important to keep your refrigerator at the correct temperature to prevent fresh food from spoiling too quickly and to slow the growth of bacteria that can cause foodborne illnesses. If the temperature is too low, some items may start showing frost on them, and if it is too high, fresh food may spoil too quickly. It is recommended to use a thermometer to ensure that the temperature is accurate and to adjust the temperature controls accordingly. The freezer should be set at 0°F (-17°C) to properly store food and prevent the growth of bacteria.
