How can you tell if raw salmon has gone bad?

Smell is the clearest signal. Fresh salmon smells faintly of the ocean. Bad salmon smells sharp, ammonia-like, or sour. Visually, look for gray patches and a slimy surface. If anything seems off, do not taste-test, just discard.

Can you eat salmon past the use-by date?

Use-by dates on raw fish are tighter than on most foods because seafood spoils quickly. If the salmon smells and looks fresh on the use-by date, it is generally safe to cook that day, but should not be held longer. When in doubt, freeze it instead.

Can you refreeze salmon after thawing?

If thawed in the fridge and still cold, yes, you can refreeze it within a day or two, with some quality loss. If thawed on the counter or in warm water, do not refreeze.

Does salmon spoil faster than other fish?

Yes. Salmon's higher fat content makes it more prone to going rancid than lean white fish like cod. Use it sooner or freeze it promptly.

How long does salmon last? And how to tell the difference between fresh and fading.

Raw salmon has a short window. Two days in the fridge is the safe upper bound, and the visible signs of spoilage are subtle enough that smell is your best guide.

Counter: Not safe (under 2 hours)
Fridge: 1-2 days (raw) / 3-4 days (cooked)
Freezer: 2-3 months (best quality)

Shelf life

How long does salmon last?

Concrete numbers by storage condition. Use the longest viable option you have time for.

Condition	Time	Note
Counter, room temperature	Under 2 hours	Bacteria multiply quickly above 40°F. Do not leave raw salmon out.
Fridge, raw	1-2 days	Coldest part of the fridge, sealed.
Fridge, cooked	3-4 days	Refrigerate within 2 hours of cooking.
Freezer, raw	2-3 months for best quality	Safe indefinitely, but quality declines after 3 months.
Freezer, cooked	2-3 months	Wrap airtight to prevent freezer burn.

Storage

How to store salmon for maximum freshness.

1

Store raw salmon in the coldest part of the fridge, typically the bottom shelf at the back. The door is the warmest spot and a poor choice.

2

If the original packaging is intact, leave it. Otherwise, wrap tightly in plastic wrap or parchment, then in foil, and place on a plate to catch any liquid.

3

Cook salmon within two days of purchase. If you cannot, freeze it within the first 24 hours, when quality is highest.

4

Always thaw frozen salmon in the fridge overnight, never on the counter. Counter thawing puts the outer layer in the bacterial growth zone while the inside is still frozen.

5

Cool cooked salmon to room temperature within an hour before refrigerating. Tightly sealed in a shallow container, it keeps three to four days.

Spoilage

How to tell if salmon has gone bad.

Strong fishy, ammonia, or sour smell (fresh salmon smells faintly of the ocean, never sharp).

Gray or dull color instead of bright pink-orange.

Slimy or sticky surface texture.

Flesh that feels mushy or falls apart at the slightest touch.

Pale, watery liquid pooling in the package.
