What is a safe way to check refrigeration temperatures?

Using a calibrated thermometer placed in the warmest part of the refrigerator is essential to accurately assess refrigeration temperatures. This approach ensures that the thermometer is measuring the temperature in a location that is most susceptible to temperature fluctuations, rather than at the door where warm air frequently enters or in locations where air circulation may not allow for proper cooling.

Calibrated thermometers provide precision and reliability, which are crucial for food safety. Accurate readings are necessary to ensure that the refrigerator maintains safe temperatures (typically at or below 40°F or 4°C) to prevent the growth of harmful bacteria in stored food.

This method is far superior to using uncalibrated thermometers, subjective methods like feeling temperatures with the hand, or taking random samples of food items, which can lead to unreliable results and potential food safety risks. By consistently checking the temperature in the warmest part of the refrigerator with a calibrated device, food safety can be effectively maintained.
