How do you know if salmon is bad?

Answer 1

If it smells bad, it is bad. The fishmonger will rarely try to peddle Salmon as fresh caught to a regular customer for fear of losing repeat business. Check the eye of the fish for clarity, cloudiness indicates poor quality. In the supermarket where things are pre-packaged look for a cut that appears silky smooth like a gemstone and has that type of color. In many countries Food Safety laws require labeling if color is added so the customer should always read the label for full disclosure. Do not hesitate to ask the market manager for a smell sample even if you are making a small purchase. If the Fish Smells Fishy reject it. If, god forbid, the question refers to a canned product that smells even slightly off, then toss it and order in a Pizza. Trust your nose because if it smells bad, it is.

Answer 2

Bad salmon is coming apart slightly, it may have brown spots or blotches. The texture should be firm and not slimy.

Answer 3

There are a few ways to tell. Look for discoloration and slime. Smell the fish, it will have a sour bad smell.
