In winter, oysters can be kept in a humid environment of 5-8 degrees for about a week. For more than a week, the state is not "vigorous", the taste and flavor are slowly deteriorating, and even life will be lost.

Oyster is a kind of shellfish that lives in the ocean. It carries some microorganisms such as bacteria. If you leave the sea, it is easy to die and deteriorate. If stored at room temperature, it can only be stored for about 1-2 days. If it is well preserved in the refrigerator, it can survive for up to a week; If it is frozen, it will last longer.

Precautions:

Some citizens like to put oysters in the freezer of the refrigerator and take them out to thaw the next day. However, this practice is actually not desirable. Store oysters, preferably in the freezer. Generally speaking, the temperature of the refrigerator at home is about 4 degrees Celsius. Oysters can keep alive at this temperature. Fresh oysters have natural antiviral ability and are safer to eat.

However, the temperature of the freezer is lower than-10 degrees Celsius. At this temperature, oysters will soon freeze to death. Because oysters are rich in nutrition, oyster meat that has lost its antiviral ability is very easy to be infected by germs, and oysters will be infected again during thawing. Therefore, eating such oysters can easily lead to severe diarrhea due to excessive bacteria.
