How long does canned tuna last in the fridge?

In this brief article we are going to answer the question, “How long does canned tuna last in the fridge?”. We will also discuss how to determine whether canned tuna has gone bad.

How long does canned tuna last in the fridge?

Canned tuna will last for 3 to 5 days in the fridge after being opened. Once opened, replace the opened can of fish in a container made of glass or a plastic bag that can be sealed and stored for later use.

It’s absolutely fine to consume tuna that has not been opened for many months. When compared to other canned fish items, tuna in a can is much more stable and has a significantly longer shelf life. 

Checking the label on the can to see what the manufacturer recommends as an acceptable shelf life is the most reliable approach to find out how long the tuna you bought in a can will really keep.

In most cases, this will take around three years. On the other hand, the shelf life of the tuna can may be prolonged by a few years if it is kept in a dry cupboard or shelf. The only need is to ensure that the can has not been dented, shattered, or otherwise compromised in any way, and that there are no air holes.

If we haven’t finished the whole can of tuna after it has been opened, we need to store the remainder in the refrigerator. Once the can of tuna or the vacuum-sealed pouch of tuna has been opened, the tuna should be stored in the refrigerator in an airtight container made of glass or plastic and covered with a lid.

It might last for three days if it is properly wrapped and kept in the refrigerator in the appropriate manner. If you want to make this period of time last for a longer amount of time, you could place the tuna in a freezer bag and keep it in the freezer so that you may eat it at a later time within a few months.

Tuna in a can that has been continuously frozen at 0 degrees Fahrenheit will maintain its safety indefinitely.

It is recommended that you do not keep your canned tuna at room temperature for a longer period of time, just as you would with any other seafood product.

Tuna that was thawed in the microwave or in cold water should be used as soon as it is no longer frozen, but canned tuna that was defrosted in the refrigerator can be stored for an additional three to four days before being used; tuna that was thawed in water or in the microwave should be used right away.

How to determine whether a canned tuna has gone bad?

The best method is to smell and examine the tuna, if it begins to emit an unpleasant odor or taste, changes in appearance, or if mold begins to grow it should be thrown out.

Throw away any tuna that is contained in cans that are rusting, bulging, leaking, or have major dent or are physically damaged.

Change in Color 


The color of tuna that has been canned ranges from light brown to light pink and sometimes has a hint of a reddish tinge. It is of no use if the color is a dark brown or even black.

Carbonation

If canned tuna encounters carbonation, it has lost all of its nutritional value. When the can was being opened, there may have been a little explosion or a loud popping sound.

Acrid smell

The tuna has an unpleasant or rancid scent about it. The presence of an unpleasant odor is crystal clear proof that it should not be consumed or kept for later use.

Temperature


Tuna that has been stored in cans in storage with temperatures that are higher than 90 degrees Fahrenheit (or 32 degrees Celsius) will become bad.

Why does canned tuna have high levels of mercury?

Larger species in the food chain, like tune, are high in mercury because they feed on smaller animals. These smaller marine animals themselves are a greater source of mercury. Due to the fact that tuna is such a big fish and a top predator, it will have a greater mercury content than fish of a smaller size.
