Poor hand washing to blame for E.coli’s outbreaks – causing poo particles to get in your MOUTH

The Sun 3 weeks ago

PEOPLE not washing their hands after going to the loo is behind the spread of superbug E.coli.

A new study has revealed that poor toilet hygiene puts you at greater risk of getting the potentially-fatal bug than eating uncooked chicken, beef or pork.

Experts found most drug resistant E. coli strains are spread between humans and not through eating raw chicken, beef or pork

And the “likeliest route” of catching E.coli is through poo particles entering your mouth.

Research author Professor David Livermore, from the University of East Anglia, said: “The great majority of strains of ESBL-E.coli causing human infections aren’t coming from eating chicken, or anything else in the food chain.

“Rather – and unpalatably – the likeliest route of transmission for ESBL-E.coli is directly from human to human, with faecal particles from one person reaching the mouth of another.”

According to statistics, E.coli is the most common cause of blood poisoning, with more than 40,000 cases each year in England alone.

Highly resistant strains

Around 10 per cent of these cases are caused by highly resistant strains which produce an enzyme known as Extended Spectrum Beta-Lactamase (ESBL).

These bacteria normally live in the intestines of healthy people and animals, and most varieties are harmless to humans.

Despite this, some strains can cause food poisoning, urinary tract infections and, in the worst case scenario, bloodstream infections.

In the study, published in Lancet: Infectious Diseases, Professor Livermore and his colleagues sequenced the genomes of ESBL-producing E.coli.

Sewage samples

They analysed 20,000 human faecal samples and 300 blood samples plus hundreds of sewage samples, animal slurry and meats including beef, pork and chicken – as well fruit and salad.

One strain – ST131 – was seen in the majority of human samples from all three sources.

However, the strains found in meat, cattle and animal slurry were mostly different.

This meant there was “little crossover” of ESBL-E.coli from animals to humans, Professor Livermore and team said.

Food poisoning bacteria

Despite this, Professor Livermore emphasised that maintaining food hygiene was still important.

And he added that people should handle raw meat carefully, not least because there are other strains of food poisoning bacteria that come through the food chain.

However, he said: “Here – in the case of ESBL-E. coli – it’s much more important to wash your hands after going to the toilet.

E.coli is the most common cause of blood poisoning according to statistics

“It’s particularly important to have good hygiene in care homes, as most of the severe E. coli infections occur among the elderly, and people may need help going to the toilet.”

Prof Neil Woodford, of Public Health England, said: “In order to tackle antibiotic resistance, we not only need to drive down inappropriate prescribing, but reduce infections in the first place.

“In order to limit serious, antibiotic resistant E. coli bloodstream infections, we must focus on thorough hand-washing and good infection control, as well as the effective management of urinary tract infections.”
