Why does canned tuna smell bad

Any deformations of the tank also show that the tuna is spoiled. When we buy a can of tuna or any other fish or seafood in general , most of us think it can last nearly forever.

Most people simply toss it into the pantry, others prefer to leave it chilled. However, in both cases, the major and essential aspect is missing and this aspect is called the canned tuna expiration dates.

A tank that was initially correctly sealed and later properly stocked according to the requirements can easily stay eatable for up to three years when being kept in a pantry unopened. In certain situations, for instance, if the storage space is dry enough, the duration of stocking can increase by a few years more!

Of course, such a long shelf life of canned tuna is supported by the proper conditions that must be provided for the foodstuff to remain consumable and of the highest quality to its longest.

Well, if the tank is still sealed and undamaged e. Remember: no food can last forever! That is why it is recommended to finish the canned tuna even if the tank looks fine and the expiry date is far away within two or a maximum of three years after it was purchased.

What about the opened foodstuff, somebody may ask? How long does canned tuna last after opening? As you might already guess, once we unseal the tank, the durability of the content disappears. Unsealed canned fish will remain harmless to eat for only three days if we stock it refrigerated and properly sealed in the airproof tank. Good question since quite many people prefers keeping it like this to prevent any possible spoilage.

In fact, keeping it chilled is not necessary since canned foodstuff can be perfectly fine in your pantry. When we place it to the fridge, we put it under the risk of overcooling at some point which might not be that good for the product.

The most worrying question everyone asks about this sort of foodstuff is: does canned tuna expire? Perhaps, people still believe or hope that foods packed this way can last forever , but we have to disappoint you, friends: canned tuna does go bad. Among the most widespread external factors that bring canned tuna expiration closer we can list the following:.

Like any other food, canned fish including tuna can be rather harmful to our wellbeing when consumed spoiled. If you eat this fish after the tuna expiry date, expect to have some unpleasant effects like upset stomach, nausea, and vomiting sorry! So, if you are not willing to end up with severe food poisoning, we would advise everyone avoid the off fish and foodstuff in general.

Compared to canned fish, the vacuum-sealed pouches also have a fresher flavor and texture. Wash it with cold water: If the fish has only recently started to smell, a quick rinse in cold water—not hot water—will remove most of the bacteria and TMA. Rinse, pat dry with a paper towel, and cook.

Soak it in milk: Casein, a protein found in milk, will bind to the TMA and leave the fish smelling fresh as ever. Tuna tends to oxidize quickly, which cause it to turn an unappetizing grey or brown. Even though it may still be relatively fresh at that point, no one wants to eat it because of the way it looks. Tuna that has gone bad will typically have dark brown streaks, streaks that might even appear black. If your tuna has any of this discoloration, it is not safe to eat. Bateluer Lifer.

Truth is canned tuna is nothing at all like fresh tuna esp when it's brine packed. Real fresh tuna and most any fish have no fishy smell. Even expensive restaurants are guilty of serving old fish. It won't make you sick, but it's nowhere near as good as fresh.

In the market day old fish is much cheaper than fish caught that day. Auric Diamond Member. Oct 11, 9, 2 As with any canned food, there are a few things to check out before you think of opening it.

If the can is leaking at all, then dispose of it straight away. A leaking can is a sign that something has gone wrong during its processing which means there is no guarantee it is safe to eat. Look for any signs of corrosion or rust on the can. Although the contents may still be fine from a rusty can, there is a risk that the corrosion has caused tiny holes to appear in the can — allowing air to reach the contents. If you can remove the rust spots with your fingers, then it should be fine to move onto the next step.

Canned tuna dented on the side may still be safe to eat, although factor in that a dent can shorten its shelf life. FSIS say if the dent is deep enough for you to lay your finger in then dispose of it. If a dent of any size is on the seam of the can then it should also be trashed as the dent may have damaged the seam. If, however, the can is bulging out at the top or bottom, always trash it!

Bulging can be a sign that the pressurization of the can has been affected which can allow bacteria to develop inside the can. More worryingly, it can also be a sign of botulinum spore activity.

Botulism is a thankfully rare foodborne illness cause by Clostridium botulinum. These bacteria usually live harmlessly on the ground, in river and sea waters, but under the right conditions, can become active and once active, C.

There have been a couple of instances of botulinum being linked with canned tuna and in fact, there was a recall of a brand of albacore tuna in which was linked to botulinum. There was a more recent botulinum outbreak in Spain , in which four people became ill. The risk of botulinum is greater from home canning than commercial canning. A leaking, very rusted, heavily dented or bulging can of tuna is not safe to eat.

If you buy tuna in pouches, then similar principles apply. If the pouch is bulging or leaking, then dispose of immediately.
