It is also vital to avoid consuming any more oysters until you have consulted a healthcare professional to ensure that the cause of the illness has been identified and treated appropriately. In the future, it is recommended that you purchase oysters from reputable sources and properly cook them before consuming to minimize the risk of foodborne illness.
How long can oysters stay in the fridge?
Oysters are a delicate and perishable seafood that require proper handling and storage to ensure their freshness and quality. Freshly shucked oysters can last up to four days in the refrigerator when stored at a temperature of 4°C (39°F) or below. However, if the oysters have been opened and exposed to air, they should be consumed within two days. It is strongly recommended to consume oysters as soon as possible after purchase to ensure their peak flavor and texture. If you are unsure about the freshness of the oysters, you can perform a sniff test by smelling the oyster’s shell. If the shell has a sour or unpleasant odor, it is a sign that the oyster has started to spoil and should not be consumed. To maximize the shelf life of oysters, it is essential to store them properly. Oysters should be kept in their original container or stored in a shallow dish with a lid or tightly wrapped in plastic wrap to prevent them from drying out. Additionally, it is advisable to place a paper towel or damp cloth at the bottom of the storage container to absorb any excess moisture and prevent the oysters from sitting in water.
