Canned tuna is one of those products you can keep in your pantry for up to five years, open it, and enjoy as if you had just bought it. How is this possible? It all depends on the tuna canning process, which involves both a sterilization phase and the complete removal of oxygen from the inside of the package. And without oxygen, bacteria cannot proliferate. This is why the product doesn’t have a real expiration date and can be consumed even past the “best before” date, as long as its appearance, odor, and consistency are normal. Also remember that, for such long-term storage, it’s a good idea to check the integrity of the can (no swelling or rust).
