Canned goods have a long shelf life. For optimal storage, keep them in a cool, dry place away from direct sunlight, ideally in a cupboard or pantry. It’s wise to use older cans first and keep newer purchases at the back, ensuring you consume them before their expiration date. Some canned foods can last up to two years past their production date.
There’s no need to refrigerate unopened cans of tuna. However, if you have leftovers, transfer them to an airtight, food-safe container and refrigerate for a day or two. If using a glass jar, you can store the tuna in its original packaging, ensuring it’s tightly sealed.
