The refrigerator is not a safe for refrigerating food. Do not exceed four days.

Many people are accustomed to concentrating on purchasing food for a whole week on weekends, and many foods will continue to be eaten next week. This is actually unhealthy.

Although the refrigerator can maintain a relatively low temperature and create conditions for food insurance, some bacteria are cold, and at this temperature, they can grow rapidly. If you eat foods that infect these bacteria, it will cause intestinal diseases. . To this end, health experts remind people -

It is best not to store food in the refrigerator for more than four days.

Experts at the University of Georgia's Center for Food Safety advised that although the food in the refrigerator looks fresh, it has actually deteriorated. For cooked meat, the storage time in the refrigerator should not exceed four days.

The common refrigerating temperature for preserving food in refrigerators is 4 ° C to 8 ° C. In this environment, most bacteria grow at a slower rate. However, some bacteria are psychrophilic. For example, Yersinia and Listeria can grow rapidly at this temperature. If you eat foods that infect these bacteria, it will cause intestinal diseases.

In the freezer of the refrigerator, the temperature is generally around minus 18 ° C. At this temperature, the bacteria are generally inhibited or killed. Therefore, the food stored therein has a better preservation effect. However, freezing does not mean that it can be completely sterilized, and some bacteria with strong anti-freezing ability will survive. Therefore, from another perspective, if the refrigerator is not disinfected frequently, it will become a "hotbed" for some bacteria.

The storage time of any food in the refrigerator should not be too long. It is best to buy it with the purchase. Because the storage time is too long, it will affect the deliciousness of the food and the odor. There are also some fruits, such as bananas, apples, etc., if they are long-lasting, they are prone to deterioration. Once they are degraded, they will emit a harmful gas. Do not store too much food in the refrigerator, which will cause the food to deteriorate due to low external temperature and high internal temperature.
