How Long Does Vacuum-Sealed Salmon Last In The Fridge

Vacuum sealing is the most convenient method of preserving seafood. As we know, among all seafood items, Salmon is considered to be one of the most consumed foods in winter. Of course, salmon lovers want to know how they can preserve this as long as possible and enjoy it for many days. If you are one of them, you are in the right place.

Here We will give you complete information on how long vacuum-sealed Salmon lasts in the fridge and how you can preserve it for longer.

How long does vacuum-sealed salmon last in the fridge:

It can only last two or three days in the refrigerator. After that, it is better to be consumed or frozen because of its rapidly deteriorating quality.
The vacuum sealing method can extend its shelf life. Vacuum-sealed Salmon can last up to a week in the fridge.
Salmon should always be stored at lower temperatures. Always choose a freezer over a refrigerator when preserving Salmon for a longer period.

Make sure to freeze it at 0 F or below after vacuum sealing if you don’t intend to use it soon. This way, we can make the fish useable for up to six months or even a year.

Vacuum sealing will prevent it from growing bacteria and absorbing the smell of other food items from your fridge. After a year, you will see a clear change in the flavor and texture of the Salmon. This indicates that it has now become a threat to your health.

The lifespan of vacuum-sealed Raw Salmon and cooked Salmon in the fridge:

Vacuum-sealed Raw Salmon may be stored in the fridge for 1-2 days. Whereas vacuum-sealed cooked Salmon will last 3-4 days in the fridge. After that, its freshness declines day by day. However, it may be eatable within a week.

But I recommend not to risk your health and try to use it within its time limit. The life span of Salmon depends on its quality.

Quality factors include how fresh it was when packing and whether it is wild Salmon or farm growing Salmon. Freshly caught wild Salmon, if vacuum seals on the same day and freezes, it will be fresh and eatable for more than a year.

shelf life of vacuum-sealed smoked Salmon in the fridge:

It has been observed that vacuum-sealed hot-smoked Salmon can last more than two weeks in the refrigerator if it is not taken out and opened even once. Vacuum-sealed Cold-smoked Salmon has a shelf life of one week less than hot-smoked Salmon.

Is vacuum sealing of Salmon better than freezing in the water:

People have different opinions about this. Vacuum sealing extends the shelf life of the fish, whereas freezing Salmon in water saves our money.

The vacuum sealing method is costly but prevents the Salmon from burning in the freezer and makes it useable for up to two years. While freezing Salmon in water can last up to four months only, it is budget-friendly.

So if you want to save your money and use your Salmon for less than three months, then you should go with the freezing in water method. However, if you have resources and are looking for a way to preserve fish for longer, vacuum sealing is best for you.

Besides these, there are some other methods to store Salmon. You can pack Salmon in foil paper or butcher paper or place it in a zipped bag to freeze it if you use it within a week.

How to defrost vacuum-sealed Salmon:

Cautiously, take it out from the vacuum-sealer bag and place it on a plate. Please keep it in a fridge for 24 hours to thaw it completely.

Another way is to place it in a bowl of cold water. Keep changing the water until the fish is fully thawed. Once the fish is defrosted completely, you can place it in the refrigerator for up to 2 days.

Don’t thaw frozen fish in its vacuum-sealed package because the air inside the package can make the fish toxic and spoil its nutritional value.

Vacuum-sealing packaging and defrosting both processes require proper cleaning and sanitizing because cleaning is the key to the longer shelf life of your Salmon.

Signs of spoiled Salmon:

Spoiled fish looks dark grey or brown. It may taste sour. Don’t wait to throw it out if it has a bad odor and slimy texture. These signs tell you that it is no longer useful to you. Eating it will endanger your life.
