The ideal temperature for a refrigerator is between 35°F and 38°F (1.6°C to 3.3°C) . This temperature range is close to freezing without being so cold that food freezes. The Food and Drug Administration (FDA) recommends keeping the refrigerator temperature below 40°F (4.4°C) to inhibit the growth of microorganisms that can cause foodborne illnesses. However, if the temperature is too low, food can freeze. Consumer Reports tests found that a fridge temperature of 37°F (2.7°C) will keep fresh food good for as long as possible, with no ice crystals on lettuce or bacteria breeding in raw meats.

Its important to use a thermometer specifically designed for monitoring refrigerator temperatures to measure the temperature accurately. Here are some additional tips to keep your fridge at the ideal temperature:

• Leave sufficient room between your food items so air can circulate freely within your fridge/freezer.
• Check that all rubber seals around your refrigerator doors are clean and in good condition, as this will help maintain the cold air inside.
• Keep your fridge away from direct sunlight, as this can cause it to heat up and make your food spoil faster.
• Clean your fridge and freezer regularly to prevent bacteria from growing.
