In winter, many families' refrigerators are overloaded. Many friends are accustomed to using the refrigerator as a treasure chest, putting a lot of food into the refrigerator in one go, and neglecting to clean the refrigerator for a long time.

In fact, this is very unhealthy, and the food in the refrigerator looks fresh on the outside, but it has actually gone bad. For cooked meats, food should not be stored in the refrigerator for more than 4 days.

The usual refrigeration temperature for food in the refrigerator is 4 to 8°C, where the growth rate of most bacteria slows down. However, some bacteria are cold-loving, such as Yersinia and Listeria can grow and multiply rapidly at this temperature, and if you eat food infected with these bacteria, it will cause intestinal diseases. In the freezer of the refrigerator, the temperature is generally about minus 18 °C, at this temperature, the bacteria will generally be inhibited or killed, so the food stored in it has a better preservation effect. However, freezing does not mean that it can completely kill bacteria, and there are still some bacteria with strong frost resistance that will survive. So, from another point of view, if the refrigerator is not disinfected frequently, it will become a "breeding ground" for some bacteria.
