what temp should a fridge be

The ideal temperature for a fridge should be set between 0°C and 5°C (32°F to 41°F), with the optimal temperature often cited as about 37°F (3°C). This range ensures food safety by slowing bacterial growth, preserving freshness, and preventing spoilage. The recommended temperature should always be below 40°F to keep food safe, with many experts suggesting around 37°F as ideal. Different parts of the fridge may have slightly varying temperatures, so using a fridge thermometer can help measure the actual internal temperature accurately. Avoid setting the temperature too cold, which can harm the freshness of some foods like vegetables, and not too warm, which risks food spoilage and bacteria growth.
