What is the ideal refrigerator temperature for food safety?
The ideal refrigerator temperature for food safety is typically between 32°F and 40°F (0°C to 4°C). Keeping your refrigerator at or below 40°F ensures that harmful bacteria are less likely to grow on perishable foods. A temperature of 37°F (3°C) is often recommended as the safest point, providing a balanced environment that is cool enough to preserve food quality while preventing spoilage.
To accurately monitor the temperature, it’s advisable to use an appliance thermometer in addition to relying on your fridge’s built-in thermostat. Many modern refrigerators come with these thermometers, but they may not always be accurate. Regularly checking the temperature ensures that you keep food stored at safe temperatures.
How can I check the temperature of my refrigerator?
To check the temperature of your refrigerator, use an appliance thermometer placed in a glass of water or on a shelf in the main compartment. After a few hours, read the thermometer to get an accurate temperature reading.
