[A new case of gastric and peritoneal anisakiasis].

A further case of anisakiasis is reported, its originality residing in the discovery of two localizations of the affection, gastric and then peritoneal, at four months' interval. This digestive disease is provoked by the larvae of nematodes that are parasites of marine mammals and for which human contamination is due to ingestion of raw or incompletely smoked fish.
