E. coli bacteria in food — commonly linked to food poisoning and the stomach pain and diarrhea that result — might also be the cause of some urinary tract infections. Researchers have found the same strains of the bacteria in chicken from stores and restaurants and in women with the infections. There’s no evidence that the germs were transmitted directly to the women through the food they ate, although that’s possible.

Still, the findings are the first to suggest a possible link between the food supply and urinary tract infections, said Amee R. Manges, an assistant professor at McGill University in Montreal and lead author of a report on the discovery. It is published in the January issue of Emerging Infectious Diseases.
