Storing Tuna Properly

Unopened canned tuna has an impressively long shelf life. As long as it’s stored in a cool, dry place away from heat and direct sunlight, it can last as long as three to five years. Always check the “best by” date printed on the can and inspect for any bulges or dents before using.

Once the can is opened, you’ll want to transfer the tuna to an airtight container. Leaving it in the can isn’t recommended, as the metal can cause a metallic flavor. Label and date the container so you’ll know when to use the tuna by, and store in the refrigerator until ready to use.

Room Temperature

Opened canned tuna shouldn’t sit out at room temperature for more than two hours (or one hour on warm days). Bacteria will start to multiply at that point, increasing the risk of foodborne illness.

Can I Freeze Canned Tuna?

Yes, you can freeze opened canned tuna. Drain any excess liquid and freeze in a freezer-safe airtight container or zip-top bag for up to three months for the best texture and flavor. Thaw overnight in the refrigerator before using.

Note that while freezing is a great way to extend the life of your tuna, it may change the texture slightly, making thawed frozen tuna best for casseroles, patties, or other cooked dishes.

How Long Does Canned Tuna Last?

Stored unopened in your pantry or cupboard, canned tuna will last for up to three to five years. Once opened, canned tuna will remain fresh for up to four days in the refrigerator or up to three months in the freezer. While it can last this long, the sooner you enjoy it, the fresher the flavor and better the texture.

Signs Of Spoilage

If you aren’t sure that your tuna is still good, it’s best to check for these signs of spoilage:

• Sour or off odor: Tuna should smell only mildly fishy, not sour or rancid.
• Discoloration: If the tuna has darkened in color or developed any unusual colors, discard.
• Slimy texture: A slimy texture is a clear sign of spoilage.
• Mold: Any visible mold means the tuna isn’t safe to eat.
• Metallic smell or flavor: Especially if the tuna was stored in its original can after opening.

Improperly stored or spoiled tuna can contain bacteria like Listeria or Salmonella, leading to foodborne illness. If in doubt, it’s best to open up a new can and discard the old.
