A new large study finds a surprising source for many urinary tract infections: the meat on our plates. Researchers traced a significant share of UTIs to E. coli strains found in chicken, turkey, pork, and beef, and say the results point to both food-supply risks and actionable steps households can take.
Nearly one in five UTIs linked to contaminated meat, study shows
Published in mBio, the investigation examined thousands of cases and retail meat samples.
- 18% of urinary tract infections were associated with E. coli strains detected in animal foods.
- The research tested more than 12,600 E. coli isolates taken from chicken, turkey, pork, and beef bought in Southern California.
- The clinical side of the study reviewed over 23,000 people diagnosed with UTIs across eight counties.
The study team argues these findings likely apply across the United States because much commercial meat is distributed nationally. Senior researcher Lance B. Price, PhD, noted that contaminated products consumed anywhere can seed infections elsewhere.
Which foods are the main culprits: poultry first, then pork and beef
Chicken and turkey showed the strongest links to zoonotic E. coli in this analysis.
Pork ranked next, and beef was associated at lower but still notable rates. The pattern suggests certain supply chains and processing steps may favor spread.
Who faces the highest risk: gender, age, and neighborhood gaps
UTIs were not evenly distributed in the study population.
- Women represented roughly 88% of the UTI cases analyzed, reflecting a far higher susceptibility than men.
- Older adults were more likely to be affected than younger people.
- People living in low-income neighborhoods had a 1.6-fold higher risk of food-linked UTIs than those in wealthier areas.
Researchers stress that socioeconomic factors shape exposure and access to safe food handling and storage, magnifying risk for disadvantaged communities.
How E. coli from animals can cause human UTIs
E. coli lives in animal and human intestines. Certain strains on raw meat can move from food to hands and surfaces.
When contaminated hands touch the body, bacteria can reach the urethra and travel to the bladder. This transmission route complements the traditional view that stool contact during sex is the main source.
Investigators also point to industrial farming and processing as potential amplifiers of risky strains. Possible interventions include vaccinating livestock against high-risk E. coli types and tightening hygiene standards at slaughter and packing facilities.
Symptoms, scale, and treatment of UTIs
UTIs remain a common clinical problem. In the U.S., they account for millions of doctor visits each year.
- Common symptoms: burning with urination, cloudy or foul-smelling urine, and frequent urges to urinate.
- Most UTIs respond to antibiotics when diagnosed and treated promptly.
Simple home practices to reduce food-linked UTI risk
Experts emphasize that many cases can be prevented with careful food handling.
Practical checklist
- Wash hands thoroughly before and after touching raw meat and after restroom use.
- Cook meat to safe internal temperatures and avoid undercooked poultry, pork, or beef.
- Prevent cross-contamination by using separate cutting boards and utensils for raw meat and ready-to-eat foods.
- Clean and sanitize surfaces and kitchen tools after contact with raw animal products.
- Store raw meat properly in the refrigerator and thaw safely to limit bacterial growth.
Public health implications and next steps
Finding that a sizable share of UTIs may stem from the food chain shifts how clinicians and policymakers think about prevention.
Researchers call for stronger surveillance of meat-borne E. coli, equitable food safety measures in vulnerable neighborhoods, and public education about safe handling at home.
