Urinary tract infections may not always come from hygiene or personal health issues — they could also be linked to what you eat. A new study in mBio found that nearly one in five UTIs in Southern California may be caused by E. coli strains traced to contaminated meat, especially poultry. Researchers say the findings reveal a growing foodborne threat that could impact millions across the country.
The team analyzed more than 5,700 bacterial samples from patients and retail meat. They discovered that about 18% of UTI-causing E. coli infections likely originated from animals. People in low-income neighborhoods faced a 60% higher risk, and women and older adults were most affected. The study suggests that modern meat production and handling methods may be fueling these infections.
Experts say prevention starts in the kitchen. Choosing meat from pasture-raised animals, cooking it thoroughly, and avoiding cross-contamination can all help reduce exposure. Washing hands and surfaces after handling raw meat is also key. Researchers say stronger food safety standards and more mindful consumer habits could help cut the risk of foodborne UTIs.
