Canned tuna, when properly stored in the fridge, can last for quite a long time. The key to ensuring its freshness and safety is to handle and store it correctly. Here are some guidelines for storing canned tuna in the refrigerator:
Unopened canned tuna: If the can is unopened, it can be stored in the refrigerator for a long time, typically up to 2 to 5 years, depending on the expiration date printed on the can. Canned goods are designed for long shelf lives, and as long as the can remains intact and undamaged, the tuna inside should remain safe to eat.
Opened canned tuna: Once you open the can, the tuna's shelf life is significantly reduced. You should transfer any unused portion of the canned tuna to an airtight container or wrap it tightly in plastic wrap. Properly stored, opened canned tuna can last in the refrigerator for around 3 to 4 days.
Remember, these are general guidelines, and the actual shelf life of canned tuna can vary based on the brand, processing methods, and storage conditions. Always check for any signs of spoilage before consuming, such as off odors, unusual texture, or mold growth. If you notice any of these signs, it's best to discard the tuna to avoid any potential health risks.
If you find yourself frequently having leftover canned tuna and unable to use it within a few days, consider purchasing smaller cans or draining and freezing the leftovers in a freezer-safe container. Frozen tuna can last for several months and can be a handy option for future recipes.
