infection with the third-stage larvae of the roundworm Anisakis marina, which burrow into the stomach wall, producing an eosinophilic granulomatous mass. Infection is acquired by eating undercooked marine fish.

anisakiasisInfestation of the upper GI tract (stomach, small intestine) mucosae by larvae of the family Anisakidae, which are common ascaroid parasites of marine fish; human infestation results from eating raw fish (e.g., sushi). The larval stage of Anisakis simplex and Phocanema (Pseudoterranova decipiens) account for all US cases of anisakiasis; another anasakine, Contracecum, may rarely cause anisakiasis.
A simplex (abdominal pain, nausea, vomiting, diarrhoea) eosinophilia with occult blood in stool if gastric anisakiasis; leukocytosis without eosinophilia if intestinal anisakiasis.
Few significant symptoms, as it does not penetrate gastric or intestinal wall.
Management gastric anisakiasis
Endoscopic removal of larva.
Management intestinal anisakiasis
Surgical excision of involved intestine.
