Storage: They can be kept in their box and stored in a cool spot in your home, like an air-conditioned room or the pantry. You may also pop them in the warmest part of the fridge, like the vegetable crisper if you do choose to chill them. As long as they are stored between 10-20 degrees, they should be fine.
Oysters will tolerate being kept on ice, but it is not the ideal. Oyster do not like being cold, and while keeping them on ice at 33 degrees might not seem like that much less than 40 degrees in the fridge, it is possible that it will shorten the shelf life of the oyster.
Containers of shucked oysters should be stored at 32 - 38 °F, ideally packed in ice. Temperatures that low may kill a live oyster, so unshucked oysters should be stored at 40 - 45 °F.
"Honestly, a lot of these things happen to us on the farm — we have oysters that are exposed to low tide in the middle of the winter, and they get hit by the freezing cold. They'll die, and the second they thaw, they open," he says.
A years-long myth about eating oysters during the summer, debunked. In the fall and winter, glasses of bubbly whites and ice-cold trays of half-shells crowd restaurant tables.
You may have heard the saying that you should only eat oysters in months that contain the letter "r," meaning oysters harvested in the warmer summer months of May through August were not safe for consumption. However, oysters are now sold and consumed year-round with little to no worries.
Rule of thumb is at least 4,000 years old. Foodie tradition dictates only eating wild oysters in months with the letter “r” – from September to April – to avoid watery shellfish, or worse, a nasty bout of food poisoning. Now, a new study suggests people have been following this practice for at least 4,000 years.
When properly cared for live oysters will live in your refrigerator for 10 to 21 days. Are they alive? When oysters are dead in their shells they are no longer suitable to eat. To see if your oysters are alive, the shell should be closed or close when tapped lightly.
There is a proportional relationship between water temperature and oyster growth rates. Very warm temperatures can have a negative effect on oxygen levels and thus hinder growth. An increase in water temperature can also prompt fewer oysters to spawn.
Oysters are not only impacted by where they grow; their flavors are affected by when we eat them, and there's a good argument to be made for doing so in the colder months. “Oysters eat cleaner and taste better in the winter,” Evan Mallett says.
Thoroughly cook your oysters: the internal temperature must reach 145°F for 15 seconds. Thorough cooking destroys vibrio bacteria (note: cooking doesn't destroy biotoxins, aka "red tide").
Tap the shell. If it closes, that means the oyster is still alive and breathing. A shell that doesn't even close (or an oyster that comes gaping open) means it is D-E-A-D and you should not buy or eat it.
Shelf Life
How long do your shucked oysters last? Shucked oysters will have a good-through date. If they go past this date, you'll want to discard them. Shucked oysters typically have a 10-14 day refrigerated shelf life upon receipt.
Once opened, oysters will keep for up to 7 days in the fridge, but be aware: they will absorb any strong flavours (for example rock melon and onion tend to taint the flavour, no matter how well packed your oysters are). When buying live oysters, make sure the shells are firmly closed.
Cold water yields crisper, leaner oysters with a sweeter finish, while warm-water oysters are meatier and hold more fat, resulting in a saltier, more briny finish. Cold-water oysters can take three to four years to develop, resulting in a more complex flavor profile.
Optimum storage temperature is 4-8°C, temperatures of 1°C or lower (especially freezing temperatures less than 0°C) can kill shellfish. Use an accurate thermometer in your refrigerator. How long can I keep live shellfish?
The best way to store them is in their bag, inside a bowl with a damp cloth over the top. But please: Do not store the oysters directly on or underneath ice. Oysters will die if they sit in fresh water. You can keep them on a tray of ice for an hour or so but avoid letting them sit in a puddle of fresh water.

We generally tell customers oysters stay fresh up to 14 days, but our results showed the period of freshness may actually be longer. We like to err on the side of caution, so 14 days from harvest is probably a good rule of thumb to follow.
Cover the oysters with a damp paper towel or damp cloth and place them in the fridge. They should keep for up to seven days like this, but it's best to eat them within a day or two. Storing shucked oysters: You can store shucked raw oysters in the fridge for four to five days.
In the days before reliable refrigeration, we were wise to consider the risks of transporting raw seafood during the hottest months of the year. Bacteria and red tide algae levels in the water rise in summer as well. Eating shellfish that absorbed these toxins could be poisonous to humans.
In the case of oysters, this little mollusk contains so much zinc that it should only be eaten occasionally. Eating them once or twice a week should land you in a nutritional sweet spot. Make sure you balance your zinc intake with enough copper — especially if you really enjoy oysters!
Seek medical treatment immediately if the person is unable to tolerate oral fluids, if fever is present, if there is blood in the stool, or if other concerning symptoms develop. For all other cases of shellfish poisoning, seek medical treatment as soon as possible.
There might be grime or mud on the shell that was stuck in the inner clamp. If you come across this, do not rinse the oyster. Instead, take a clean towel and carefully wipe off any grime or mud. Place on a bed of ice with other shucked oysters and serve.
