The popularity of such raw fish dishes makes it important for consumers to be aware of this risk.[10] Fish that spend part of their life cycle in brackish or freshwater, like salmon are a particular problem.A study in Seattle, Washington showed that 100% of wild salmon had roundworm larvae capable of infecting people.Infection risk of anisakis is particularly higher in fishes which may live in a river such as salmon (sake) in Salmonidae or mackerel (saba).Such parasite infections can generally be avoided by boiling, burning, preserving in salt or vinegar, or freezing overnight.
