Contaminated Meat Linked to UTIs in New Study
Health Points
- Up to 1 in 5 UTIs may be linked to E. coli from contaminated meat, especially in low-income communities.
- Chicken and turkey had the highest risk of E. coli contamination among meats studied.
- Hand washing, cooking meat thoroughly, and sanitizing food prep areas can help lower UTI risk.
New research from Southern California suggests that E. coli in meat could be responsible for nearly a fifth of urinary tract infections, with a higher impact on residents of low-income neighborhoods.
Women and older men are more likely to have UTIs linked to animal-sourced E. coli, according to genomic analysis of urine and store-bought meat samples.
“This result suggests that livestock may serve as a reservoir contributing to the E. coli pool infecting humans, but it does not establish that contaminated meat directly caused these UTIs,” says Jason Kim, MD, a urologist at Stony Brook Medicine.
Chicken and turkey samples showed the highest E. coli contamination, while the study’s limitations could mean beef’s role is underestimated.
Foodborne E. coli can cause infection when bacteria from undercooked meat or poor hygiene enter the urinary tract.
“When people handle or consume contaminated meat, these bacteria may colonize the gut and later ascend the urinary tract, causing infection,” says Dr. Kim.
UTI symptoms typically include burning during urination, urgency, cloudy urine, and lower abdominal discomfort.
Kim recommends seeking medical advice early if you have symptoms, as uncomplicated UTIs respond well to treatment in most cases.
“UTIs impose major healthcare and productivity costs and can lead to serious complications. Over half of E. coli sepsis cases begin as urinary infections,” he adds.
Older adults, women, and people with weakened immunity should be especially careful with food safety to limit UTI risks.
The CDC suggests washing hands after handling raw meat, sanitizing surfaces, and thoroughly cooking meat to limit exposure to E. coli.
“Avoid cross-contamination between raw meats and other foods, especially items ready to eat, in the kitchen and refrigerator,” advises Francisco Diez-Gonzalez, PhD, director of the Center for Food Safety at the University of Georgia.
Public health efforts should address both food safety in meat production and the higher risk faced by low-income populations.
“The scale of overlap is unexpected and important for public health, but it represents correlation rather than proven cause-and-effect,” says Kim.
