Abstract

We examined food consumption patterns of U.S. students temporarily living in Guadalajara, Mexico. Consumption of foods prepared in Mexican homes was associated with an increased risk of acquisition of diarrhea. Foods from commercial sources and private Mexican homes in Guadalajara were subsequently examined for contamination with coliforms, fecal coliforms, and bacterial enteropathogens. For comparison, selected restaurant foods were obtained in Houston, Tex. Food obtained from Mexican homes showed generally higher counts of coliforms and fecal coliforms than those obtained from commercial sources in Mexico and Houston. The foods in Mexico, both from homes and commercial sources, commonly contained Escherichia coli and occasionally enterotoxigenic E. coli. Foods in Houston were not contaminated with E. coli or enterotoxigenic E. coli. Salmonella (17 isolates), Shigella (4 isolates), and Aeromonas hydrophila (1 isolate) were found only in the foods obtained from Mexican homes. Enterotoxigenic non-E. coli Enterobacteriaceae was recovered with approximately equal frequency from all food sources.
