anisakiasis (MONDO_0015200, a Monarch Disease Ontology term) is infection with roundworms of the genus anisakis. Human infection results from the consumption of fish harboring roundworm larvae. The worms may cause acute nausea; vomiting; or penetrate into the wall of the digestive tract where they give rise to eosinophilic granuloma in the stomach; intestines; or the omentum. Also known as: Anisakis simplex infection, infection by Anisakis larva.
