A: Once your canned tuna has been opened it must be kept in a refrigerator if you did not eat all of it. If wrapped properly and stored in your fridge it should last for around three days.
1 You can refrigerate canned tuna in a tightly covered container for up to two days. 2  If you are storing your canned tuna in an unheated garage, ensure that it does not freeze during the winter months. This can cause the can to bulge or rust.  Use canned tuna by the expiration date on the can.
