How to tell if canned salmon is bad?

Certain indicators point out bad canned salmon. You should consider the appearance, color, texture, and smell of your canned salmon along with the condition of the can to reach a final verdict whether or not it has gone bad.

Appearance

If you spot a mold or other organic growth on your canned salmon then it means that your canned salmon has gone bad and the best thing you can do in this scenario is to get rid of it.

It is worth mentioning that you should refrain from smelling canned salmon that has molds on it as molds can produce mycotoxins that if enter your body even via inhalation can disrupt your gut microflora thereby weakening your immune system.

Color 

If you notice that there is a discoloration in the canned salmon (the color of fresh and safe canned salmon is pink) or if it is dull then it is the indication that your canned salmon has gone bad and it is better to discard it.

Texture 

If you feel something slimy or gooey while touching the canned salmon then it means that your canned salmon has gone bad and it is better to discard it. 

But keep one thing in mind that rinsing the canned salmon won’t help you in this scenario as you won’t be able to get rid of the bacteria. Rather rinsing the bacteria-laden canned salmon will put you at risk of cross-contamination as the bacteria will spread in the utensils and other food items that will come in contact with the water from the canned salmon that has gone bad.

It is worth mentioning that you should wash your hands thoroughly after touching the bacteria-laden canned salmon or else the bacteria will transfer from your hands to any other thing that comes in contact with your hands.

Smell 

If you smell a very intense fish smell while taking a sniff test of your canned salmon then it means that your canned salmon has gone bad and you should discard them.  

Condition of can

If you spot a leakage or bulging in the can of your salmon, then it is better to discard it as there are great chances that bacteria and other microbes would have already found their way to your canned salmon and would have spoiled it.

If microbes somehow found their way to your canned salmon and have spoiled it then the best thing you should do is to discard it.

Devouring a spoiled fish can also result in Scombroid poisoning. In the improperly stored salmon, bacteria can produce scombroid toxin and this toxin does not even get killed when the salmon is cooked. The ingestion of salmon that has this toxin can result in Scombroid poisoning that is characterized by nausea, vomiting, flushing, abdominal cramps, diarrhea, and headache. 

Other symptoms of Scombroid poisoning may include itching, hives, burning sensation in the mouth, and fever.  

In case you have devoured spoiled canned salmon and are now suffering from vomiting and diarrhea then you should immediately take medical help and try to drink as much water as possible so that while the body is getting rid of the toxins in form of diarrhea and vomiting, the water that you drink will protect your body against dehydration that vomiting can otherwise result in.

The shelf life of canned salmon

Unopened canned salmon lasts for about 3-5 years when stored properly in a cool, dry, and dark corner of the pantry away from direct sunlight and heat.

Once you open your canned salmon, the clock starts ticking, and there is a limited time during which you can enjoy the best quality and flavor of your canned salmon. Once you have opened the can, it is recommended to transfer the remaining salmon in the air-tight container or the plastic zipper bag and store it in the fridge at or below 40 degrees Fahrenheit. Open canned salmon stored this way in the fridge lasts for about 3 days.

On the other hand, if you have opened your canned salmon, it lasts for about 2 hours when kept out in the open (or 1 hour if the temperature is above 90 degrees Fahrenheit). Bacteria grow best at 40 to 140 degrees Fahrenheit and there are chances of your open canned salmon to be already bacteria-laden if it is left in the open for more than 2 hours.

If you want to prolong the shelf life of your opened canned salmon, then what you can do is to transfer it to the plastic freezer bag and store it in the freezer. Salmon that is properly stored in the freezer lasts for about 9-12 months.

It is worth mentioning that the figures discussed above are the estimated shelf life of the canned salmon and it is the time during which you can enjoy the best quality of your canned salmon.
