Nearly 1 in 5 UTIs linked to contaminated meat, claims US study

A four-year investigation titled The Foodborne UTI Project, published in the journal mBio, has found that nearly one in five urinary tract infections (UTIs) among patients in Southern California were caused by E.

coli strains traced to contaminated meat. The researchers warned that similar patterns could be emerging across the United States.The study analysed more than 2,300 UTI cases and determined that about 18% were genetically linked to E. coli found in grocery store meat samples from the same region. Turkey and chicken were most frequently contaminated, followed by pork and beef.According to the US Centers for Disease Control and Prevention (CDC), UTIs occur when bacteria enter the urethra and infect the urinary tract.

They are among the most common infections globally, particularly affecting women and older adults.Lance B. Price, senior author of the study and a professor at George Washington University, said the research reframes UTIs as not only a personal health concern but also a food safety issue. He noted that the findings highlight the need for preventive measures targeting communities that face higher exposure risks.

The study also found that people in low-income areas were 60% more likely to develop foodborne UTIs than those in wealthier neighbourhoods. The researchers suggested that this disparity may be linked to weaker food safety oversight, inadequate retail conditions, and poor hygiene practices in food handling.Price emphasised the importance of investing in studies that explore how social and economic factors affect health, saying that an individual’s risk of infection should not depend on their ZIP code.Until stricter industry and regulatory standards are enforced, the authors advised the public to follow basic precautions such as washing hands thoroughly after handling raw meat, avoiding cross-contamination in the kitchen, and ensuring that meat is cooked properly to reduce the risk of infection.

What are urinary tract infections (UTIs)?

UTIs are infections that occur when bacteria, most often Escherichia coli (E. coli), enter the urinary tract through the urethra and begin to multiply in the bladder.

They can affect any part of the urinary system, including the kidneys, bladder, ureters, and urethra. Women are at higher risk because of their shorter urethra, which allows bacteria easier access to the bladder.

What are the symptoms?

According to the CDC, symptoms of a bladder infection (cystitis) include pain or burning during urination, frequent urination, a strong urge to urinate even when the bladder is empty, blood in the urine, and pressure or cramping in the lower abdomen or groin.If the infection spreads to the kidneys (pyelonephritis), symptoms can include fever, chills, lower back or side pain, nausea, and vomiting.

How are UTIs treated?

Most UTIs are treated with antibiotics prescribed by a doctor. Drinking plenty of fluids, especially water, helps flush bacteria from the urinary system. For recurrent infections, healthcare providers may recommend longer antibiotic courses or additional tests to identify underlying causes. Preventive steps include practising good hygiene, avoiding cross-contamination while cooking, and ensuring meat is cooked thoroughly before consumption.Note: The information provided in this article is for educational purposes only and is not intended as medical advice.
