Incidence of Listeria monocytogenes in Fresh and Smoked Fish in Iran

摘要

The psychrotrophic pathogen Listeria monocytogenes is a widespread microorganism that has been isolated from many foods, including fish and shellfish (Farber 1991; Fuchs and Surendran 1991; Dillon et al. 1992; Dillon and Patel 1992; Jemmi and Keusch 1992; Ben Embarek 1994; Heinitz and Johnson 1997; Weagant et al. 1988). The several outbreaks that have occurred since 1979 have implicated vegetables and dairy products (Dillon et al. 1992) as well as undercooked fish and shellfish (Heinitz and Johnson 1997) as vehicles of infection. An epidemic of prenatal listeriosis in New Zealand suggested a possible link to the consumption of raw fish. That outbreak resulted in five deaths from 22 cases (Dillon and Patel 1992). A few cases have identified undetcooked fish and shellfish (Heinitz and Johnson 1997). However, many sources of Listeria outbreak are never established.
