Expiration & Storage Tips
When does canned tuna in water expire?
Unopened canned tuna in water can typically last 3 to 5 years beyond the printed date, making it an enduring pantry staple. Once opened, it should be used within 2 to 3 days when stored in the refrigerator. If you've frozen your canned tuna after opening it, aim to use it within 2 months for best quality.
How do you tell if canned tuna in water is bad?
The signs of spoiled canned tuna in water can be detected right from the can. A bulging or leaking can is a definite no-go. Once opened, if it looks discolored, has a slimy texture, or carries a strong or unpleasant odor, discard the leftovers without tasting. Always remember, the rule of thumb is, when in doubt, throw it out!
Tips for storing canned tuna in water to extend shelf life
• After opening, transfer any unused canned tuna into a covered glass or plastic container and refrigerate immediately.
• Avoid storing the tuna in its original opened can, as the metal may transfer to the food and give it a metallic taste.
• Freezing opened tuna in a sealed container can also be an option for longer storage. Make sure to leave a small space at the top of the container, as the contents may expand when frozen.
• To defrost, transfer the container from the freezer to the refrigerator for several hours or overnight. Note that frozen tuna changes texture upon defrosting, so it's best used in cooked dishes like casseroles or sauces.
