M. Pontello et al., A COMMUNITY-BASED OUTBREAK OF SALMONELLA-ENTERICA SEROTYPE TYPHIMURIUM ASSOCIATED WITH SALAMI CONSUMPTION IN NORTHERN ITALY, Epidemiology and infection, 120(3), 1998, pp. 209-214
An outbreak of Salmonella enterica serotype Typhimurium belonging to p
hage type (PT) 193 occurred in autumn 1995 and involved 83 individuals
in a large area of Northern Italy (Lombardy Region). Epidemiological
and microbiological investigations of strains isolated from clinical a
nd food specimens revealed that the vehicle was a batch of salami, pro
duced on 4 September 1995 by a local firm. The outbreak was contained
when the batch was withdrawn from sale. Insufficient ripening of the s
alami had allowed the salmonella to survive, emphasizing the need to d
efine criteria for the ripening process of foods such as salami.
