Immediately refrigerate leftover canned tuna in a glass or plastic container. Do not leave the tuna in the opened can, as it may become rusty once open. You can refrigerate canned tuna in a tightly covered container for up to two days. 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.
