1–2 days at 4°C (40°F) or colder (opened). Keep it sealed so it does not pick up moisture or odours.

How long does canned seafood last in the freezer?

Not listed. FoodKeeper gives no freezer time for canned seafood.

How long does canned seafood last at room temperature?

It is not meant to be kept at room temperature. Refrigerate it.

How long does canned seafood last after opening?

1–2 days in the fridge once opened. The printed date stops applying the moment you break the seal.

How long is canned seafood good for past the expiration date?

FoodKeeper gives unopened canned seafood 1 year in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.

How can you tell if canned seafood is bad?

Fermented, yeasty or sour beyond the product's usual tang. Separation that does not stir back, or a slimy layer. Darkening or a change in colour at the top of the jar.
