Why doesnt canned tuna have a expire date on it?

Canned tuna typically doesn't have an expiration date because it is considered non-perishable when stored properly. Instead, it often features a "best by" or "use by" date, indicating optimal quality rather than safety. As long as the can remains sealed, undamaged, and stored in a cool, dry place, the tuna can remain safe to eat for several years beyond that date. However, for best taste and texture, it's advisable to consume it within a few years.
