Anisakiasis is a human gastrointestinal parasitosis that results from accidental ingestion of infective larvae belonging to the Anisakidae family. Eleven codfish samples were analyzed and 64% did not conform to the present legislation, because they contained nematode larvae from the Anisakidae family and were therefore unfit for consumption.

In this paper we evaluate and discuss the tissue damage due to Anisakis larvae in experimentally infected sea bass (Dicentrarchus labrax). This is the first endoscopic and laparoscopic study, that has revealed in two fishes hemorrhages and/or nodules on the serosal surface of the intestine. The evidence of tissue change is an unusual occurrence in Anisakis infected teleost fish.

Anisakiasis is a disease caused by infection with an anisakid larva, primarily Anisakis simplex, through the ingestion of raw marine fish, known worldwide as “sashimi”, or of a wide variety of undercooked marine fish. In Japan, anisakiasis is quite prevalent, with more than 1,000 new cases estimated to be diagnosed annually (1). At the end of 1999, “The Food Sanitation Law Enforcement Regulatio...
