1. A box of oysters packed in a foam box can be stored in a cool and ventilated place and eaten within the same day if there is an ice pack inside.

2. Low temperature can inhibit the reproduction of bacteria and reduce the loss of oysters, thus prolonging the survival period of oysters. Just put a box of oysters in the refrigerator without washing, and they will die faster after washing with water, but the temperature should be controlled at 1-2 degrees Celsius, not below zero. If the temperature is low, they will freeze and can be stored for about 3-5 days at most.
