The IHEEM London Branch recently held a well-attended meeting at which members were updated on the latest approved methods to control waterborne organisms within hospitals and other care facilities.
Part of the presentation included a report on dental surgeries describing their complicated pipework and controls which require regular flushing to prevent equipment causing dangerous aerosols transporting bacteria directly into patients’ mouths.
Ian Bateman said that scientists at Porton Down had reported that 52 out of 55 samples taken from dental units failed EU drinking water safety standards. It was found that water lines contained a wide range of bacteria including legionella. This poses a serious danger when treating patients who are suffering from HIV or cancer and have reduced immunity. David Turner of the British Dental Association had admitted to New Scientist that “people with compromised immune systems should worry”.
