How Long Are Oysters Good For?

Unopened oysters will last between 5-7 days in the fridge when stored properly on an ice bed with the deeper side down to help them retain water.

An ideal oyster should be firm to the touch with a fresh salty taste, boasting tight shells that shine brightly without wrinkles and boast tight closure. An oyster’s foul smell or slimy texture should serve as a warning sign and no longer safe to consume.


If you plan on enjoying oysters for dinner, it is usually best to purchase them close to when you intend on serving them; that way they’ll remain fresh and flavorful. Unfortunately, that may not always be feasible; luckily though, oysters can last up to two days in your fridge even without being shucked!

To properly store oysters, place them in a bowl covered by damp cloth, place this container into the fridge on a bed of fresh solid ice and ensure no part of it touches their shells (this could lead to spoilage). Alternately, you could place the oysters into a cooler but make sure there’s plenty of airflow and make sure no part of them touch water; also check periodically to drain away melted ice or add additional as necessary.

Refrigeration can also help keep oysters alive, although this doesn’t typically extend their shelf life very much. Furthermore, note that frozen oysters should only ever be consumed after being cooked prior to consumption!

As an easy way to check if your oysters are fresh, tap lightly on their shells. A live oyster should sound solid and closed when tapped; dead ones, however, will either feel hollow or break easily – ensure any dead oysters are discarded immediately as they may contain bacteria that cause food poisoning.

As with any food product, oysters must be thoroughly checked prior to consumption for freshness and safety. Any with a cloudy hue such as grey, brown, black, or pink should likely have been spoiled and should be disposed of quickly.

As a rule of thumb, it is best to eat seafood within two or three days after purchasing it. Proper storage in the refrigerator will ensure they will taste best; thus avoiding purchasing shellfish at markets and stores that sell spoiled products for too long is wiser.


If you buy them still in their shells, store them in the coldest part of your fridge or in an ice cooler until ready to eat them – don’t break out their shells until just before it’s time! Otherwise they will quickly perish once sucked from their home in their shells before starting to decompose and spoil unless cooked quickly before consumption.

Oysters can last up to 4 days in their shells in the fridge if you aren’t planning on eating them right away, making refrigeration worth while. Before shucking them, run them under cool water to rinse off any surface grit that might make its way into the meat; washing may ruin their delicate texture more readily than running under water does.

Once it comes time to enjoy them, store oysters away from any foods that smell or taste similar to seafood, such as the smelly foods found on grocery store shelves. Instead, store them at the bottom of your fridge or on a plate covered with wet paper towel to protect from other foods that might come their way.

Whole shelled oysters may keep for up to one week in the refrigerator if they are stored with their cupped side down and covered by a damp paper towel, to prevent their moisture evaporating away and allow them to relax and breathe more comfortably. You may turn them over in your fridge if desired in order to extend their shelf life further.

When you’re ready to eat them, run them under cool water to remove any grit and make them easier for you to consume. Serve on a half shell with lemon juice, horseradish sauce, cocktail sauce or caviar as desired.

To open an oyster easily, hold it with your dominant hand so the round, cupped side is facing down and the pointy flat end points towards you. Use a knife against the shell and jab into hinge. Some prefer inserting closer, though this may prove more challenging.


Oysters will last longer in your refrigerator when stored properly, due to their ability to endure colder temperatures for longer than most seafood options. But keep these factors in mind when storing oysters so they remain deliciously fresh!

One of the best ways to store oysters is on a bed of ice, as this will allow them to retain their juices and be easier to open. Although you could store them in your freezer, that is not advised since they could spoil before you are ready to consume them. When placing them in your refrigerator make sure their deep cupped side faces down to avoid them clumping together; cover them with a towel as an extra safeguard and keep them moist and fresh!

Cooked oysters may last two weeks in the refrigerator before spoiling; oysters in their shells should be consumed within four days of being stored there to prevent spoilage. You can also freeze oysters to extend their shelf life; just remember to thaw them out first to ensure freshness!

Before handling oysters, it is vital that you wash your hands to prevent bacterial contamination and wear gloves for protection from their rough exterior shells. Furthermore, when cooking them it’s essential not to overcrowd your pan so they can cook evenly.

To prepare oysters, first remove them from their shells and discard the top shell. Next, season each oyster with salt and pepper using a spoon before mixing the mixture with olive oil evenly using a knife. You may add lemon juice or Tabasco sauce if desired before plating your oysters on a plate for service with bread or crackers.


Oysters should be eaten shortly after purchase if you bought them alive and in their shell. Use their sell-by date as your guideline; otherwise, store for up to two days in your refrigerator in proper conditions if concerned about quality or timing.

Oysters require temperatures between 36-40 degrees Fahrenheit (2-4 Celsius). Oysters need enough cold to support their metabolisms without freezing, or else they risk death. You might see oysters stored on ice at seafood markets because this helps ensure they reach optimal storage temperatures and the ice prevents any melting that might otherwise happen during transport or storage.

When it comes to storing live oysters, you must ensure they do not come in contact with one another as this could expose them to bacteria and pathogens that will make them sick. You should also avoid placing the oysters directly in fresh water, melting ice or the freezer as this will likely kill them off quickly. MasterClass suggests placing the oysters on a tray with small spaces between each one before covering them with damp towel before refrigerating them.

Shelled oysters should be stored similarly, though periodically check on them and turn them over so they don’t dry out too much. You could add crushed ice as an aid, though be wary not to overfill their containers as too much could cause overflowing and spillage into other parts of your fridge.

If you’re unsure whether or not your oysters are still good, gently tap them on a bench. If they are alive and their shell closes spontaneously when touched gently on, that indicates freshness – otherwise discard them immediately as this indicates their expiration. You can also tell whether dead ones have gone bad by their foul odor and slimy texture – something fresh ones won’t exhibit.
