Farmed salmon are often infested with sea lice, parasitic relatives of prawns and shrimp, that cause direct damage, starve their host and increase vulnerability to disease.
How common are parasites in farmed salmon?
This is because farmed salmon are exclusively fed strongly heated and processed dry-feed which therefore cannot contain parasites such as Anisakis. In 2015, the Norwegian Institute of Marine Research examined 4,184 farmed salmon from 37 salmon farms and did not find any Anisakis.
Is farmed salmon less likely to have parasites?

How do I know if my fish has parasites?
Look to see if your fish has cloudy eyes, white patches or is gasping for air, rubbing on objects and is listless. Fish lice could cause these symptoms.
