A new study suggests there may be more likely dangers lurking in the bathroom.

Scientists in the US used an ultra sensitive method to detect bacteria in shower-heads in bathrooms across the country.

Results showed that around 30 per cent of shower-heads had “significant amounts” of Mycobacterium avium, a bacterium linked to breathing illnesses that most often infects people in poor health but can also cause illness in healthy individuals.

These bacteria are often found in water. However, in shower-heads the bacteria tend to clump together to form a slimy “biofilm”, at a concentration more than 100 times greater than is found in ordinary water.

Professor Norman Pace, who led the study, said: “If you are getting a face full of water when you first turn your shower on, that means you are probably getting a particularly high load of Mycobacterium avium, which may not be too healthy.”

These results may also provide an explanation for the rise in Mycobacterium avium infections in recent years, coinciding with people preferring showers over baths.
