Burden and transmission of zoonotic foodborne disease in a rural community in Mexico.

Background: The foodborne transmission and human health impact of Salmonella and Campylobacter infections have rarely been evaluated at the population level in highly endemic settings.

Methods: A prospective 15-month cohort study of 127 infants and 119 elderly people was combined with animal and food surveillance to determine the incidence and severity of Salmonella and Campylobacter gastroenteritis in a comparatively prosperous rural community in Mexico.

Results: Salmonella and Campylobacter were isolated in up to 75% and 57%, respectively, of raw retail meat and in up to 4.

Diagnosis by a Combination of Typing Methods of a Salmonella typhimurium Outbreak Associated with Cured Ham.

This paper describes the usefulness of combining typing methods (antibiotyping, phage typing, plasmid profile, and ribotyping) in the characterization of a Salmonella enterica serotype Typhimurium ( S. typhimurium ) strain as the causal agent of an outbreak associated with cured ham, Serrano variety, which is an unusual infection source of Salmonella . Human isolates and the majority of ham isolates showed identical biochemical profiles, antibiotypes, plasmid profiles, and ribotypes.
