Some computer keyboards harbour more harmful bacteria than a toilet seat, research has suggested.
Our chemist tests at its London offices found equipment carrying bugs that could cause food poisoning. Out of 33 keyboards swabbed, four were regarded as a potential health hazard and one harboured five times more germs than one of the office’s toilet seats. Microbiologist Dr Peter Wilson said a keyboard was often “a reflection of what is in your nose and in your gut”. During the Which? tests in January this year, a microbiologist deemed one of the office’s keyboards to be so dirty he ordered it to be removed, quarantined and cleaned. It had 150 times the recommended limit for bacteria – five times as filthy as a lavatory seat tested at the same time, the research found.
