Recent investigations suggest 95% of UK garden water butts may be contaminated with Legionella bacteria, the bug responsible for the potentially deadly Legionnaires’ disease.
Scientists working on behalf of Public Health England at the Porton Down facility have discovered most of the water butts in British gardens are likely contaminated with the potentially deadly Legionella bacteria. As part of a recent survey, they obtained samples from 113 water butts to determine whether the bacteria were present. Just six water butts were discovered to be free from the potentially deadly bacteria.
