Showerheads can be a breeding ground for infectious bacteria.
According to a recent study by researchers from the University of Colorado at Boulder, dirty showerheads in homes may well be a potential breeding ground for infectious bacteria – Mycobacterium avium, which can cause lung infections when inhaled or swallowed. The study, funded by the National Institute of Occupational Safety and Health and the Alfred P. Sloan Foundation, is part of a larger effort that is analyzing the microbiology of the indoor environment and its role in spreading to illness within the house. Comment: BUT, what evidence is there that people have been made ill by taking a shower? This seems to be an example of money looking for a spending source. In a depressed economy it is this kind of research that makes academics look bad, It is certainly not a random sample of homes in the US. Ivan Illich would have loved this action.
