It is always important to keep in mind that tuna can in fact go bad, so you will need to make sure that you look at the expiration date that is on the can which you get from the store. By making sure that you eat the tuna before the “best by” date, you will be able to avoid any problems with food poisoning. It is also important that you are able to recognize some of the signs that tuna has gone bad, including a particularly fishy smell as well as a change in color which is usually green.

Sometimes I can be hard to tell if tuna has gone bad based on the taste alone, which is why you will want to make sure that you pay attention to the above signs in order to avoid getting sick. While it is true that most canned tuna will have an expiration date on it, you will find that it isn’t always completely accurate.
