Anisakid nematode parasites are adult worms that feed in the gastric tract of amphibians, reptiles, birds and mammals (whales and dolphins). Sea foods are the principal sources of human infections with these larval worms. These parasites are known to occur frequently in the flesh of cod, haddock, fluke, pacific salmon, herring, flounder, and monkfish. The disease is transmitted by raw,undercooked or insufficiently frozen fish and shellfish, and its incidence is expected to increase with the increase in the number of sushi and sashimi bars. The survey of cod marketed in the State of São Paulo is probably the first to be reported. This work deals with a parasitological survey of Anisakis from 22 samples. 9 (40,9%) were infected with nematodes, 6 of which (27,3%) belonged to the anisakidae family. Larve from two genera, Anisakis and Pseudoterranova, of the family Anisakidae, have been definitelyidentified from human cases. Although anisakiasis is not a major public health problem, there is a need for regulation in the fish industry and for consumer information. Vermes da família Anisakidae são nematóides parasitas do aparelho gástrico de mamíferos marinhos como focas, baleias e golfinhos. Larvas destes parasitas são encontradas freqüentemente em carne de salmão, bacalhau, arenque, atum, hadoque, linguado (hospedeiros intermediários). A infecção humana resulta do hábito do homem se alimentar com peixe cru, insuficientemente cozido, congelado, salgado ou defumado, contendo larvas infectantes vivas do nematóide. As espécies mais comumente envolvidas na infecção humana são Anisakis simplex e Pseudoterranova decipiens. O objetivo deste trabalho é registrar a ocorrência de larvas da família Anisakidae em bacalhau comercializado no Estado de São Paulo. Foram analisadas 22 amostras de bacalhau importado, provenientes da Delegacia do Consumidor (Decon), do Centro de Vigilância Sanitária do Estado de São Paulo e de empresas particulares, entre dezembro de 1997 e dezembro de 1998. Foram encontrados nematóides em 9 das ...
