OUTBREAK OF SALMONELLA-ENTERITIDIS IN THE LIVORNESE AREA IN 1992

The results report the incidence of Salmonella serotypes, isolated by the Biotoxicology O.U. of M.P.S. of U.S.L. 13 (Livornese area), betwee n 1984 and 1992. The data show a frequency decrease of Salmonella sero types infantis and typhimurium, and an extraordinary increase in human infection due to Salmonella serotype enteritidis, becoming in recent years the leading serotype (55,2% in '92). This prevalence may be asso ciated with the consumption of raw eggs and egg-containing food. Inves tigations carried out in poultry farms, contrary to what Regional cont rol organisms have recently pointed out, resulted steadily negative. H ere are also presented the data related to Salmonella isolation from f oods analyzed in our laboratories during 1992.
