Latest temperature standards for food sample retention.

The temperature range of food sample retention control is between 0 degrees Celsius and 4 degrees Celsius.

The US Food and Drug Administration requires all hotels, restaurants, schools, enterprises and institutions to formulate a food sample retention system. It is not only to protect people's lives, but also to distinguish the responsibilities in food safety and provide effective evidence for analyzing the causes of sudden food poisoning incidents. Among them, food samples must be stored in a professional refrigerator with constant temperature and refrigeration, and the temperature should not be too high or too low to prevent the samples from deteriorating and moldy due to temperature.

After collecting samples from school canteens, they should be kept at about 5 degrees Celsius for more than 48 hours. They should not be frozen.
