You've Been Storing Canned Tuna All Wrong

Canned food is one of those things that's great to keep on hand for those days when you're running low on groceries and can't get to the store, like when you're snowed in or simply don't have time. One of the most common canned foods you'll find in many people's homes is canned tuna. It's packed with healthy protein and makes for a delicious lunch when you're in a pinch (tuna salad sandwich, anyone?!). 

People love canned tuna so much that study done in 2009 by the National Fisheries Institute reported that 56 percent of Americans surveyed keep three or more pouches of tuna at home at any given time, with 25 percent admitting they keep five or more. That's a lot of fish! If you're one of those who likes to always have a can or two (or three or five) in your kitchen, take note: You may not be storing it properly.

Canned tuna needs to be cool, but not too cool

First things first: You should absolutely keep your cans of tuna away from heat (i.e. don't put it in the cabinet above the stove or in direct sunlight). Heat will cause your tuna to spoil much quicker and could make it unsafe to eat. Now that we've got that out of the way, where should you store your tuna? Many food sites, including the The Spruce Eats, recommend keeping canned tuna in a cool, dark cabinet, like the pantry or any cupboard that's away from heat sources and that has a closing door. It is not necessary to refrigerate unopened cans of tuna.

However, once you open a can of tuna, you absolutely should keep it in the refrigerator. Eat Right suggests transferring your fish to a plastic bag or container before placing it in the fridge, where it will stay fresh for one to two days.
