Yes, frozen salmon can go bad if it’s not stored properly. If the salmon is exposed to air, it can develop freezer burn, which dries out the fish and makes it less flavorful. Salmon that has been freezer-burned is still safe to eat, but it may not be as delicious as fresh salmon. Make sure you follow certain rules (mentioned below) when you freeze it.
What Causes Frozen Salmon to Expire?
Frozen salmon can go bad for a variety of reasons. Here are a few of them.
Not Cleaned Before Freezing
If you don’t properly clean your salmon before freezing it, the fish will be more likely to go bad. Salmon should be gutted and scaled before being placed in the freezer.
Not removing the guts and scales from your salmon before freezing it can cause the fish to go bad more quickly. The guts of the fish can contain bacteria that can contaminate the flesh of the salmon.
Scales can also harbor bacteria, which can transfer to the flesh of the salmon when it’s thawed.
Frozen for Too Long
If you keep salmon in the freezer for too long, it will eventually go bad. The length of time that salmon can be stored in the freezer depends on the quality of the fish when it was originally frozen.
Fresh, properly cleaned and gutted salmon can be stored in the freezer for up to six months. If the salmon is not as fresh or if it wasn’t cleaned properly before being frozen, it should only be stored for three months.
Not Using a Moisture-proof Container
If you don’t store salmon in a moisture-proof container, it can go bad more quickly. Moisture from the air can cause the fish to dry out and develop freezer burn.
To prevent this, make sure to store salmon in a moisture-proof container, such as a zip-top bag or a vacuum-sealed bag.
You can also wrap the salmon tightly in plastic wrap before placing it in a zip-top bag. This will help to keep the fish from drying out.
Not Maintaining Proper Temperature
If the temperature in your freezer is too warm, salmon can go bad more quickly. Salmon should be stored at 0°F (-18°C) to maintain its quality.
If your freezer is not cold enough, consider investing in a chest freezer or an air-tight container that will keep the salmon at a consistent temperature.

How to Store Frozen Salmon Perfectly
If you want your salmon to last as long as possible in the freezer, there are a few things you can do.
Cleaning
As we mentioned before, it’s important to properly clean your salmon before freezing it. This means gutting and scaling the fish.
Once the salmon is cleaned, pat it dry with a paper towel. This will help to prevent freezer burn.
Proper Packaging
Once the salmon is cleaned, it needs to be properly packaged. A moisture-proof container, such as a zip-top bag or a vacuum-sealed bag, is recommended. Before putting the salmon in a zip-top bag, cover it tightly with plastic wrap.
Labeling
Make sure to label your salmon with the date it was frozen. This will help you keep track of how long it’s been in the freezer. Because salmon can only be stored in the freezer for a certain amount of time, it’s important to keep track of when you froze it.
Storing in the Coldest Part of the Freezer
Salmon should be stored at 0°F (-18°C). To ensure that the salmon stays at this temperature, store it in the coldest part of your freezer, which is against the bottom and along the rear wall.
When the freezer door is opened, this section will remain the coldest because it is the furthest from the door.

Signs of Spoiled Frozen Salmon
There are a few signs that you can look for to tell if salmon has gone bad. If you find any of the signs visible on your frozen salmon it’s better not to use it.
Color: One of the first signs that salmon has gone bad is a change in color. Fresh salmon is pink or red, while spoiled salmon will have a brownish or grayish hue. If you see any changes in color, it’s best to throw the salmon out.
Texture: Another sign that salmon has gone bad is a change in texture. Fresh salmon is firm and moist, while spoiled salmon can be dry and mushy. If you notice any changes in texture, it’s time to say goodbye to your fish.
Smell: Salmon that has gone bad will have an unpleasant odor. If you notice a strong fishy smell, it’s best to discard the salmon. When in doubt, trust your nose. If the salmon smells bad, it probably is.
Disappearing white line: Salmon has wonderful white lines all over it. The loss of these lines indicates rotting in this fish. More scattered and gray lines will be seen. This clearly indicates that the salmon is unfit to eat.
Slimy layer: If there is a slimy layer on the surface of the salmon, it indicates the presence of bacteria. If you see a slimy & sticky layer you should avoid cooking your salmon.
