Oysters can last two days in your refrigerator if kept on ice, though for optimal results it is advised that they be consumed within one day to preserve freshness and deliciousness. To reduce spoilage and lower bacteria risk, changing out the ice regularly and placing in an insulated cooler filled with crushed ice may be more suitable than leaving them on their own.

If you don’t have access to refrigeration, oysters can still be kept fresh with some added salt to the water; be mindful not to add too much as too much can sour and ruin their flavor! Alternatively, use a mixture of water and lemon juice as another means of preservation.

Storage options for oysters also include freezing them to extend their shelf life, but in this instance you must first shuck them before freezing to make them easier to consume when defrosted in a pan or oven.

Fresh oysters have an intoxicating fragrance that reveals their quality. If an oyster emits an unpleasant odor, it is most likely spoiled and should be discarded immediately. Any liquid-leaking oysters should also be disposed of immediately as this indicates they may contain harmful bacteria.

Fresh Water

Store oysters correctly to maintain fresh, crisp, and tasty seafood. Store oysters in their shells in the coldest part of your refrigerator or cooler with ice and only shuck when ready to eat them – as oysters are highly sensitive to environmental changes, they should not be kept with other food items that will spoil.

An oyster’s liquor, the salty liquid that fills its shell when alive and at its prime, can help determine its quality. If its liquor has dried up or has disappeared altogether, that indicates the oyster no longer meets standards and should be discarded. Alternatively, taste test an oyster by taking some of its liquid from its shell before biting into it; its flavor should be salty with some sweetness present.
