Store-bought meat may fuel a surprising share of urinary tract infections, according to a George Washington University-led study published in mBio. By sequencing more than 5,000 E. coli samples from Southern California patients and retail meats and using a 17-marker algorithm to trace origins, researchers estimated that 18% of UTIs diagnosed from 2017 to 2023 were likely foodborne. Riskier strains often came from chicken and turkey, and rates were higher in low-income neighborhoods. The team urges broader studies and notes that standard food safety steps, sealed packaging, thorough cooking, and handwashing, can lower risk.
