How to tell if canned tuna is bad

Smell

Fermented, yeasty or sour beyond the product's usual tang.

Texture

Separation that does not stir back, or a slimy layer.

Colour

Darkening or a change in colour at the top of the jar.

Mould

Any fuzz on the surface or lid — discard the jar.

Canned tuna past the expiration date

Best-by and sell-by

FoodKeeper gives unopened canned tuna 3 years 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.

Past the date

Canned tuna past its best-by date is usually safe if stored well; check smell, look and taste before using.

How to keep canned tuna fresh longer

  • Refrigerate after opening unless the label says otherwise.
  • Use a clean utensil each time; crumbs and double-dipping shorten shelf life.
  • Wipe the rim and close the lid tightly.
