Review of Evidence for Zoonotic Listeriosis.

Foodborne transmission, especially by milk and milk products and raw vegetables, appears to be the major means of zoonotic transmission of listeriosis. Four major foodborne outbreaks of listeriosis were reported in the United States and Canada 1979-1985. Implicated foods were cabbage, pasteurized milk, and Mexican-style soft cheese. Circumstances of the outbreaks and the implicated foods support the concept of zoonotic transmission of listeriosis.
