A widely unknown cause of urinary tract infections and why they are getting harder to treat
Across the UK, doctors are seeing more urinary tract infections (UTIs) that don’t respond to standard treatments. What used to be a simple, one-cure solution now sometimes requires multiple rounds of antibiotics — or even hospital admission.
The reason? A common gut bacterium called E. coli (Escherichia coli), responsible for most UTIs, is becoming resistant to antibiotics.
What is a UTI?
Your urinary tract includes the urethra, bladder, ureters, and kidneys. When bacteria like E. coli enter this system, it can lead to a UTI. Symptoms include:
- Burning when you pee
- Needing to go often
- Blood in the urine
- Lower belly pain
If the infection spreads to the kidneys, it can cause:
- Fever and chills
- Back or side pain
- Feeling very unwell
Left untreated, kidney infections can cause serious damage — or even lead to sepsis, a life-threatening response to infection.
Where do these bacteria come from?
E. coli lives in the guts of humans and animals. While most strains are harmless, some can cause infections — and some are now highly resistant to antibiotics. Recent studies show that many of the resistant strains found in people are genetically linked to E. coli found in poultry, particularly chicken.
The dark side of factory-farmed chicken
Every year, over 1 billion chickens are slaughtered in the UK. Most are raised in giant sheds, with up to 50,000 birds per building. There’s no natural light, barely any space, and no escape from stress, faeces, or infections.
Because diseases spread so quickly, entire sheds are often treated preventively with antibiotics — not to cure illness, but to stop it from happening in the first place. This routine use of antibiotics helps bacteria evolve resistance — and these resistant bacteria can end up on your plate.
At the slaughterhouse, the speed of processing often leads to faecal contamination of meat. Even if the chicken is cooked thoroughly, bacteria can spread via hands, surfaces, or cutting boards — especially when handling raw meat.
In short: you might get sick from bacteria on your salad, not your chicken.
Can you treat a UTI yourself?
If caught early, some mild UTIs can be managed by:
- Drinking plenty of water might help
- Eating cranberries (they may help prevent bacteria from sticking to the bladder wall), can prevent but not cure a UTI.
But if symptoms persist or worsen, antibiotics are needed. And if those no longer work — we’re in trouble.
A bigger public health problem
Antibiotic resistance isn’t just about UTIs. It’s part of a larger crisis. In the UK alone, nearly 2,000 deaths in 2022 were linked to drug-resistant infections stemming from factory-farmed animals.
Global experts warn that by 2050, antibiotic resistance could kill 10 million people annually — more than cancer today.
What can you do?
- Wash your hands thoroughly after handling raw meat
- Avoid cross-contamination in the kitchen (use separate boards, knives, etc.)
- Cook poultry thoroughly — until juices run clear and the meat reaches 75°C
- Support farms and retailers that reduce antibiotic use
- Use antibiotics only when prescribed by a medical professional
It’s not just about dinner
Factory farming doesn’t only harm animals — it endangers public health. The same system that floods our supermarkets with cheap chicken is breeding the next generation of superbugs.
And if a new bird flu variant or resistant bacteria makes the jump to humans… well, we know how that story goes.
We’ll be wearing masks again. Wondering how it all began. And telling ourselves we couldn’t have seen it coming.
But we could.
