1. If you buy oysters with shells, first prepare a foam box, put four or five ice packs, put the oysters with shells in order, cover the foam box and put them in the fresh-keeping area of the refrigerator for preservation. For half-shell oysters, just wrap the exposed part of the meat with plastic wrap, put it in a sealed box with a shell and store it in the fresh-keeping area of the refrigerator.

2. The temperature in the freezing area of the refrigerator is low, generally minus seven or eight degrees. Put the oysters in for preservation. If properly preserved, oysters with shells can generally be preserved for two to three days, and oysters with half shells can be preserved for five to seven days. It is suggested that the storage time should not be too long to avoid deterioration and affect the taste and nutrition.
