- E. coli bacteria frequently found in meat are possibly linked to half a million cases of Urinary Tract Infections (UTIs) annually.
- The research provides genetic proof that certain UTIs could be traced back to E. coli present in store-bought chicken, turkey, and pork.
- Approximately 8% of UTIs caused by E. coli are believed to stem from food sources, primarily meat.
- Though not definitive, this study insists on the necessity for safe cooking habits and proper hygiene to protect against foodborne E. coli.
- For recurrent UTI patients, moving to a vegetarian diet isn’t the resolution, instead, foster healthy routines like a nutritious diet, sufficient sleep, exercise, and proper water intake for better immune function and reduced UTI risk.
As notorious as E. coli bacteria are for causing food poisoning, recent research suggests that the same microbes often found in meat may be responsible for roughly half a million cases of urinary tract infections (UTIs) annually.
Connection Between E. Coli and UTIs
UTIs are an extremely common ailment, affecting more than half the female population at least once in their lifetime. Predominantly, these infections are traced back to E. coli bacteria.
While E. coli are infamous for causing food-poisoning, the majority of the strains are actually harmless. E. coli bacteria are an integral component of the vast ecosystem of beneficial bacteria known as your body’s “microbiome.” The issue arises when these gut-dwelling bacteria find their way to your urinary tract through your stool, thus resulting in a UTI.
This forms the root of most UTI cases, as suggested by study author Lance Price, a renowned microbiologist and professor at George Washington University.
Genetic Evidence from Price’s Research Team
The research team discovered genetic evidence indicating that some UTIs could be caused by E. coli found in store-bought chicken, turkey, and pork. These bacteria reach the urinary tract in the same way as other UTI-causing E. coli, but the source differs.
Based on their estimates, approximately 8% of UTIs caused by E. coli stems from a food source. Consequently, this suggests that around a half a million such infections occur annually amongst Americans.
UTIs: A Common Problem for Women
Women have a higher tendency to get UTIs, experiencing them up to 30 times more often than men. This is largely due to their anatomical structure, where the urethra opening is situated close to the anus —facilitating an easier pathway for E. coli to the urinary tract.
Symptoms of UTIs and Their Serious Implications
Typically, UTIs occur in the bladder, causing symptoms including frequent urination, burning sensation during urination, and lower belly pain. However, in a minor percentage of cases, UTIs could lead to more serious infections, even life-threatening, if they spread to the kidneys or blood. Thus, prevention of these infections, even on a small scale, could yield significant benefits.
The theory of foodborne E. coli playing a role in UTIs isn’t new. For instance, a previous study from 2005 made the same conclusion.
Role of Foodborne E. Coli
This latest study took a broader approach to understand the extent of foodborne E. coli contributing to UTIs. Over a year, the researchers periodically bought samples of raw chicken, turkey, and pork from various brands at nine major grocery chains. They also collected E. coli samples from patients at a major medical center.
Through thorough analysis of E. coli genomes from both meat and patients, the researchers identified DNA segments unique to strains that colonize animals humans consume. Consequently, this led to the development of a mathematical model predicting the likelihood of E. coli originating from humans or food.
According to this model, 8% of the patients suffered from a UTI due to E. coli infection originating from meat. Based on these figures, the study estimates that foodborne E. coli can cause around half a million UTIs every year.
However, this study’s conclusions are not definitive, and therefore, more research is essential, says Dr. Johanna Figueroa, a urologist at Northwell Health. Nonetheless, no one argues against the need for safe cooking and proper bathroom hygiene to protect against foodborne E. coli.
Steps to Prevent E. Coli Infection
For people with repeat UTIs, moving to a vegetarian diet is not advised. However, healthy habits like a nutritious diet, ample sleep, excercise and proper water intake can support a stronger immune function, contributing to reduction of UTI risks. From a larger perspective, this research may be used by the industry to reduce the presence of specific E. coli strains in the food supply.
