What opening the package actually costs
Opening the package is the decision that settles this page. Sealed, the item holds 1 year in the pantry; once open it holds 2 days open in the fridge, the same food measured in days instead of years, a drop of 182 times. On the same shelf it sits 26 of 70, between Grapeseed oil at 1 year and Cereal at 12 months. Canned seafood and canned are the same food in the source list.
Every storage figure the USDA publishes for this item
The USDA gives this item a pantry and a refrigerator figure and no freezer figure at all, the pattern behind 79 of the 466 foods in the data.

Can you freeze seafood?
The USDA prints no freezer time for seafood. Frozen at 0 °F any food stays safe; whether it is still good after thawing is a matter of quality. Keep the fridge at 40 °F or below and the freezer at 0 °F.
How to tell if seafood has gone bad
Go by the date first: seafood keeps 1–2 days in the fridge once opened. A sour or off smell, mold, slime or an odd color mean it goes out. The bacteria that make people sick change none of these, so past its window it goes out even if it seems fine. Never taste to test.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 1 day to 2 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: Seafood, canned is an animal food, or made with one. Past it, it is not safe to eat: throw it out without tasting, because bacteria build up while food still looks and smells fine.
The figure in the pantry here is a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food.
It is past the date. Now what?
Say the calculator above puts Seafood, canned past its 1 day to 2 days in the fridge once opened window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Items that behave the same way
All 6 of the 6 items nearest this item keep exactly as long as it does, 1 year, so the ranking around it is a tie rather than an order.
Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
