2. Oyster is a living thing in the ocean, which is suitable for preservation at 4-6 degrees. If it is soaked in water and stored directly at room temperature, it can generally be stored for about 1-2 days. If it is soaked in water and then stored in the refrigerator, it can be stored for about a week at most, because the cold storage environment can inhibit the growth of bacteria to a certain extent, which is more in line with the living environment of oysters, so the storage time will be relatively short.
