Nematode larvae of medical importance found in market fish in Iran

Two species of fish, tuna fish (Euthynnus spp.) from the Persian Gulf and pikeperch (Lucioperca lucioperca) from the Caspian Sea were examined for nematode larvae. The larvae of Anisakis which is considered to be one of the zoonotic helminths, was found in 75 percent of the tuna fish and 20 percent of the pikeperch. The possible role of fish as a source of infection in man in Iran is discussed.
