Anisakis is a genus of parasitic nematodes that have lifecycles involving fish and marine mammals. They are infective to humans and cause anisakiasis.People who produce immunoglobulin E in response to this parasite may subsequently have an allergic reaction, including anaphylaxis, after eating fish infected with Anisakis species. Adult stages of Anisakis simplex or Pseudoterranova decipiens reside in the stomach of marine mammals, where they are embedded in the mucosa, in clusters. Unembryonated eggs produced by adult females are passed in the feces of marine mammals . The eggs become embryonated in water, and first-stage larvae are formed in the eggs.
