Canned or pouched tuna, cooked in the pack. The can keeps a year longer than the pouch, which is a packaging difference rather than a fish one.

How long it keeps

Unopened, this keeps 3 years — which is what puts it on the long shelf.

Counted from the day you bought it and the date on the package. Figures are the USDA FSIS FoodKeeper table's, for unopened storage at room temperature; FoodKeeper counts a month as 30 days.

The table was not pulled from USDA — fsis.usda.gov answers 403 to non-browser clients from this machine — so it came from a mirror of the data.gov dataset and its vintage is unverified. Treat a single figure as indicative, not as a use-by date.
