what should refrigerator temperature be

The ideal temperature for a refrigerator is between 35-38°F (1.6-3.3°C) . The Department of Agriculture recommends setting the temperature gauge a few degrees below 40°F (4.5°C) to ensure food safety. Consumer Reports tests found that a fridge temperature of 37°F (2.8°C) will keep fresh food good for as long as possible, with no ice crystals on lettuce or bacteria breeding in raw meats. The optimal temperature for keeping foods cold is also 37°F (2.8°C) . While 40°F (4.5°C) protects harmful bacteria from growing, anything too much lower can cause food to freeze when you dont want it to. If your refrigerator is older, it may not maintain the same temperature all over, so its recommended to put two thermometers in an older fridge and check both regularly to ensure the temperature remains under 40°F (4.5°C) in all sections.
