A health expert has warned of a lesser-known symptom that could indicate an E. coli infection. Earlier this month, the UK was hit by an E. coli outbreak with nearly 300 confirmed cases caused by contaminated sandwiches sold at major retailers including Asda, Tesco, Aldi, Sainsbury’s and Boots.
Typical symptoms of the infection include diarrhoea, stomach cramps and fever, but a urinary tract infection (UTI) could also be a sign of E. coli, according to Kiran Jones, pharmacist at Oxford Online Pharmacy. He has highlighted the symptoms to watch out for and how to handle a UTI triggered by E. coli.
How does E. coli cause UTIs?
A 2023 study suggested that E. coli found in meat could be responsible for UTIs, as the bacteria identified in UTIs could be traced back to various types of meats such as turkey, chicken and pork.
In 2018, it was discovered that E. coli infections linked to romaine lettuce were causing UTIs in those infected.
E. coli is a common type of bacteria present in the intestines, and poor hygiene can lead to its transfer to the urethra and urinary tract, resulting in infection. Once it reaches the urethra, the bacteria can adhere to the lining of the urinary tract, build resistance to the immune system and antibiotics, before moving to the bladder and causing cystitis – a bladder infection.
The inflammation and symptoms of a urinary tract infection (UTI) are triggered by our immune system’s response in the bladder. If left untreated, it can escalate into a more serious kidney infection.
Signs to look out for
If your urinary tract is infected with E. coli, you may experience symptoms such as abdominal or pelvic pain, a burning sensation during urination, frequent and urgent need to urinate, and cloudy or foul-smelling urine.
These symptoms usually manifest between three to five days after consuming contaminated food or drink and are similar to those of a regular UTI. It’s crucial to seek medical advice promptly if you suspect a UTI. The fastest way to confirm an E. coli-induced infection is through a urine sample test.
Preventing and managing an E. coli-induced UTI
Ensure your food is safe
Food is often the primary source of E. coli infection, so it’s vital to ensure it’s safe before consumption. Rinse all raw fruits and vegetables with room temperature water before preparing them for eating or cooking. All meat should be thoroughly cooked.
Use clean utensils when preparing food and prevent cross-contamination by keeping dairy products, raw meat, and fruits and vegetables separate.
Maintain good hygiene
E. coli is a bacteria that can be contracted by touching various surfaces, hence the importance of regular hand washing to minimise risk.It’s also crucial to keep household surfaces, particularly in the kitchen, sanitised.
Antibiotics
Antibiotics are typically prescribed for UTIs to eradicate the infection-causing bacteria. Completing the prescribed course can prevent the infection from spreading to the kidneys and expedite recovery.
Drink fluids
Staying well-hydrated can help flush out bacteria from the urinary tract through increased urination. Hydration also dilutes urine, reducing irritation to an inflamed urinary tract and providing some relief.
Avoid alcohol, caffeinated and carbonated drinks or acidic beverages as these can exacerbate urinary tract and bladder irritation. Instead, aim to drink at least two litres of water daily, consider probiotic drinks to introduce beneficial bacteria to your gut, and opt for sugar-free cranberry juice to protect your bladder lining.
The effectiveness of cranberry juice in treating UTIs is debated and results vary, but one study linked it to UTI prevention and management.
