Such parasite infections can generally be avoided by boiling, burning, preserving in salt or vinegar, or freezing overnight. Even Japanese people never eat raw salmon or ikura (salmon roe), and even if they seem raw, these foods are not raw but are frozen overnight to prevent infections from parasites, particularly anisakis.

The parasite is then carried in the salmon until the next spawning cycle. The myxosporean parasite that causes whirling disease in trout has a similar life cycle. [ 2 ] However, as opposed to whirling disease, the Henneguya infestation does not appear to cause significant incapacitation of the host salmon — even heavily infected fish tend to ...
1. Farm-Raised Salmon. Some farm-raised salmon may contain more parasites than its wild-caught counterpart due to the densely populated conditions of fish farms, which can foster a breeding ground ...
Gyrodactylus salaris, commonly known as salmon fluke, [1] salmon killer, or the Norwegian salmon killer is a tiny monogenean ectoparasite which lives on the body surface of freshwater fish. [2] This leech-like parasite has been implicated in the reduction of Atlantic salmon populations in the Norwegian fjords . [ 3 ]
The source of L. salmonis infections when salmon return from fresh water has always been a mystery. Sea lice die and fall off anadromous fish such as salmonids when they return to fresh water. Atlantic salmon return and travel upstream in the fall to reproduce, while the smolts do not return to salt water until the next spring.
Raw fish should be frozen to an internal temperature of −20 °C (−4 °F) for at least 7 days to kill parasites; home freezers may not be cold enough. [47] [48] Historically, fish that live all or part of their lives in fresh water were considered unsuitable for sashimi due to the possibility of parasites (see Sashimi article).
The Michigan Department of Natural Resources euthanized Atlantic salmon that were sick with bacterial kidney disease. Michigan Department of Natural Resources euthanizes more than 31,000 Atlantic ...
Diphyllobothrium is a genus of tapeworms which can cause diphyllobothriasis in humans through consumption of raw or undercooked fish. The principal species causing diphyllobothriasis is D. latum, known as the broad or fish tapeworm, or broad fish tapeworm.
