ABSTRACT

Bacterial enteropathogens acquired from contaminated food are the principal causes of travelers’ diarrhea (TD). We evaluated desserts obtained from popular restaurants in the tourist city of Guadalajara, Mexico, and Houston, Texas, to determine coliform and Escherichia coli contamination levels and presence of diarrheagenic E. coli known to be important in TD. Contamination for all organisms was seen for desserts served in Guadalajara restaurants. Desserts should be considered as potentially risky foods for development of TD among international visitors to developing regions of the world.
