A recent study has shed light on a concerning hidden foodborne risk that affects millions of people, particularly in Southern California. The research, published in the journal mBio, reveals that nearly one in five urinary tract infections (UTIs) in the region may be caused by E. coli strains transmitted through contaminated meat.
The study, titled “Zoonotic Escherichia coli and urinary tract infections in Southern California,” highlights the impact of foodborne pathogens on public health. According to the senior author of the study, Lance B. Price, UTIs have traditionally been viewed as a personal health issue. However, the findings suggest that they are also a significant food safety concern.
Individuals living in low-income neighborhoods are at the greatest risk of contracting UTIs from foodborne E. coli strains. This disparity underscores the need for targeted interventions to protect vulnerable communities. Price, who is also the founding director of the Antibiotic Resistance Action Center at the George Washington University, emphasizes the importance of addressing social determinants of health to prevent infections based on ZIP code.
UTIs are a common health problem, with E. coli being the primary cause. The bacteria are often found in raw poultry and meat, making it challenging to determine the extent of foodborne transmission. To address this gap, researchers collected E. coli samples from UTI patients and retail meat in the same neighborhoods. By using a genomic modeling approach, they estimated the origin of each bacterial strain, whether human or animal.
Key findings from the study include:
– 18% of UTIs in the study population were linked to foodborne E. coli strains, predominantly found in chicken and turkey.
– Individuals in low-income areas had a 60% higher risk of foodborne UTIs compared to wealthier neighborhoods.
– Women and older men were identified as high-risk groups.
While the study focused on Southern California, the researchers believe that the problem extends beyond the region. Future research aims to refine predictive models for identifying meat sources and expanding the findings to other areas and infection types.
Consumers can protect themselves by following safe food handling practices, such as buying securely sealed meat, thoroughly cooking poultry, preventing cross-contamination, and advocating for food safety policies. The study underscores the importance of proactive measures to reduce the risk of foodborne infections.
