Quick answer
Refrigerate opened canned oysters immediately and follow the exact package. Crown Prince and Chicken of the Sea recommend using refrigerated leftovers within 2–3 days. Chicken of the Sea specifies 35–40°F. An unopened shelf-stable tin belongs in cool, dry storage; a can marked “Keep Refrigerated” needs cold storage before opening too.

These instructions cover commercial canned oysters, including shelf-stable smoked tins. Fresh shucked oysters and refrigerated smoked seafood are different products. USDA shelf-stable food guidance
Keep the date attached to the right tin
An unopened quality date does not become a fresh period after purchase. Use the actual package rather than assigning every brand a generic number of years. Store tins away from damp cupboards, stove heat and temperature extremes. Use earlier dates first. USDA
A best-by date concerns quality, but neither an old date nor a current one settles the condition of an individual can. Storage and damage still matter. Do not sample suspicious contents to answer the question. FDA storage guidance
Put opened leftovers away promptly
Remove what you need with a clean utensil, cover the remainder and record the opening date. An oil-packed tin still needs the maker's after-opening refrigeration. For the named brands, transfer leftovers as instructed; USDA's general permission to refrigerate food in its can does not cancel their more specific directions.
Opened seafood should not sit out more than two hours, or one hour above 90°F (32°C). Count time on the serving table; putting the remainder back in the fridge does not erase it. For a picnic, an unopened shelf-stable tin is easier to manage than warm leftovers. FDA seafood handling
FAQs
Can I freeze the remainder?
Chicken of the Sea permits suitable airtight containers or freezer bags, but discourages freezing because quality can suffer. It says not to freeze its products in their original can, pouch or cup. Follow your brand, and freeze only safely handled food; no universal freezer-month allowance is established here.
Are green oysters always spoiled?
Crown Prince explains that an oyster's plankton diet can cause green coloration. That does not identify every unusual patch. Color alone cannot clear suspicious food or a damaged tin. Crown Prince FAQ
Do smoked canned oysters need cooking?
Chicken of the Sea says its seafood products are fully cooked and ready to eat. Read your own label rather than assuming every smoked seafood product has that status. Refrigerated smoked oysters are outside this shelf-stable-tin advice.
