The common cold storage temperature of food in the refrigerator is 4℃ to 8℃. In this environment, the growth rate of most bacteria will slow down. But some bacteria are psychrophilic, such as Yersinia, Listeria, etc., which can grow and reproduce rapidly at this temperature. If you eat food infected with this kind of bacteria, it will cause intestinal diseases.

Although the food in the refrigerator looks fresh, it has actually gone bad. Cooked meat should not be stored in the refrigerator for more than 4 days. The duration of other ingredients is as follows:

Beef: refrigerated 1 ~ 2 days, frozen for 90 days.

2. Steak: refrigerated for 2~3 days and frozen for 270 days.

3. Sausages: refrigerated for 9 days and frozen for 60 days.

4. Chicken: Refrigerate for 2-3 days and freeze for 360 days.

5. Fish: frozen for 0/~ 2 days and 90~ 180 days.

Precautions for expanding data:

Meat bought in the supermarket can be stored in the refrigerator for a short time, but it can't be stored for a long time, especially it can't be thawed repeatedly.

First of all, the meat bought in the supermarket has been on the supermarket counter for a long time, and it is likely that it was not very fresh when it was bought. If there are bacteria or mold in it, even if it is put in the refrigerator, it will cause corruption at a very slow speed. Although this phenomenon is slow, if it takes too long, the meat may go bad.

Secondly, meat stored in the refrigerator will breed an ice crystal, which will exist in the cells of meat for a long time. It will destroy the cell wall and cell membrane of cells, resulting in a large loss of nutrients in meat. This kind of ice crystal will gradually become larger as time goes by.

Therefore, it is best to divide the meat in the refrigerator into small pieces in advance and take out one of them when you need to eat, instead of taking out the whole piece every time.
