Although sometimes touted as lower quality than fresh, canned meat has its benefits. From flavor preservation to affordability and a lengthy lifespan, canned meat is convenient and easy to use. Plus, it retains the proteins, fats, and nutrients found in fresh, whole meat. Among the many canned meats you can find at supermarkets, canned tuna is one of the most popular. In fact, canned tuna is the second most popular seafood item in America. But does it ever go bad?
The short answer is yes, canned tuna does eventually go bad. But according to the United States Department of Agriculture, commercially canned tuna will last for up to five years -- plenty of time to put it to use. However, home-canned tuna will last for only one year. Bear in mind that when the can is not properly stored, it can corrode and rust, destroying the tuna and hastening the expiration process.
Five years is a long time with a can of tuna, but it's easy to reduce its shelf-life by not properly storing it.For starters, keep unopened canned tuna in a cool, dark place such as a pantry or a snack cupboard. Storing the can at room temperature is essential as high temperatures can accelerate the deterioration of the tuna or cause the can to swell or burst due to the expansion of the food and gases. Avoid exposing the can to any moisture, as this facilitates rust and damage to the metal.
If you've opened a can of tuna but only used a small portion of it, you should immediately store the leftovers in the refrigerator where they will stay fresh for up to four days.So, what's the best way to store this opened canned tuna?Although you can keep the tuna in the can covered with a universal can lid or foil, it's best to transfer the remaining tuna to an air-tight container such as a lidded jar or resealable plastic bag to maintain flavor and freshness. Pro tip: Your leftover canned tuna oil makes a flavorful fried egg.
Recognizing Signs Of Spoilage
Canned tuna is a hearty and enduring food that boasts an extensive shelf life, and as long as you properly store it, you'll get the most out of those five years. However, recognizing signs of spoilage and expiry is hugely important for food safety.
If you notice extreme changes in the tuna can's shape -- ditch it. A bulging tuna can is a common sign of spoilage, indicating gas production from microbial activity and chemical reactions inside the can. Similarly, deeply dented cans, especially those close to the seal, can invite bacteria into the tuna. Rust is another sign that it's time to replace your can of tuna, as the chemical process of rust development can cause tiny holes to open on the surface of your can.
Because of the can's low-oxygen conditions, mold is not likely to grow on an unopened can of tuna. But just because you can't see mold, doesn't mean it isn't there. To err on the side of caution, stick to the USDA guidelines and consume the tuna within five years. Of course, if you notice mold or foul smells on your leftover tuna, ditch it immediately.
Whether you're using it for a traditional tuna salad recipe or an upcoming hiking trip, get the most out of your tuna can by maintaining high standards for food safety. Safe eating is happy eating!
A good rule of thumb for canned seafood, such as canned salmon or canned tuna, is that it can be safely kept in a cool dark pantry for 5 years. But really, as long as the seal remains unbroken, a tin can last nearly indefinitely.
Sell-by, use-by, and best-by dates generally indicate when a food item will be at its peak quality. Manufactured canned goods are still safe to eat after that time.

Canned fish — such as tuna, salmon, and sardines — can last up to three years after they're packaged. Why? "Canning foods removes all air and places it in vacuum-sealed containers that are then heat processed," says Rumsey. "This destroys microorganisms and prevents new bacteria from getting in."
Most shelf-stable foods are safe indefinitely. In fact, canned goods will last for years, as long as the can itself is in good condition (no rust, dents, or swelling). Packaged foods (cereal, pasta, cookies) will be safe past the 'best by' date, although they may eventually become stale or develop an off flavor.
If you are pregnant, avoid canned tuna altogether.
You can get omega-3 fatty acids from other seafood that are low in mercury, such as oysters, salmon, and sardines. Those are particularly high in omega-3s, but other low-mercury fish—scallops, shrimp, squid, and tilapia—supply some as well.
It is best to store unopened commercially canned foods in a cool and dry place (such as in a cupboard). For best quality use closed canned fruits within 18 months. Low-acid canned foods (canned peas, potatoes, corn, meat, poultry, etc.) can keep their best quality for two to five years.
Fish has gone bad if it's 1 or 2 days past the sell-by date on the packaging. This indicates that the fish's freshness is gone and the meat has expired. Other signs include cloudy eyes, a slimy coating, a sour smell, mushiness, or discoloration. Discard spoiled fish and sanitize any surfaces it has touched.
Once canned, the fish is placed in a special cooker that super-heats the cans to a very high temperature under pressure.The tuna ends up vacuum-sealed and sterilized in the can due to this process, and that's what gives it its shelf life and the ability to remain safe to eat while stored at room temperature.
High acid foods such as tomatoes and other fruit will keep their best quality up to 18 months; low acid foods such as meat and vegetables, 2 to 5 years. While extremely rare, a toxin produced by Clostridium botulinum is the worst danger in canned goods.
How can botulism be prevented? Only cooking or boiling food destroys botulinum toxin. Freezing does not destroy the toxin. If you prepare or eat traditionally prepared Alaska Native foods, the food safety tips below may decrease your risk of botulism.
We have a wise and witty customer who asked this question and we gave him our standard response that when stored in a cool, dark pantry you can enjoy that canned salmon or canned tuna many years, even decades from date of purchase.
Most canned fish last more that 10 years after the sell by date. Open the ton and smell. If it smells like normal then it is good to eat. Also bad canned food is normally black.
One to two years past the best-before date for canned, bottled or jarred pastas, meats, fish, tomato sauces and condiments. If these items are packaged in boxes or bags, they'll be accepted up to six to 12 months past the best-before date.
A: Home-canned foods are at their absolute best if eaten within one year of canning them. They will slowly lose flavor, color, and nutrients over a period of years, eventually becoming something you wouldn't want to eat. You can slow down this loss in quality by keeping the jars stored in a cool, dark place.
You will, however, want to refrigerate any leftovers from your FinerFin product or any other canned tuna you may eat. You don't want to leave opened tuna out for more than two hours because that's when bacteria can begin to form.
Sell-By Date: Refers to the last day a retailer can display a product for sale; typically a food is safe to eat for 10 days after the Sell-by Date if refrigerated properly. Use-By Date: Refers to the last day a product will maintain its optimum freshness, flavor, and texture.
