Scientists have revealed the filthy secrets that lurk in PC keyboards and smartphones, with one in six mobiles contaminated with faecal matter.
Researchers have discovered that computer keyboards contained 7,500 bacteria per swab - much more than an average toilet seat, which has 5,400.
John Norris of mouldcheck.co.uk told the Sun on Sunday: "It's no surprise - we eat at our desks, drop all sorts of things on our keyboards and rarely wash our hands before we start using the computer.
"There are products out there to clean your keyboard, but few bother."
Microbiologist Dr Peter Wilson said a keyboard was "a reflection of what is in your nose and gut".
A surprise finding was that handbags contain a high level of bacteria, including E. coli and even traces of faeces.
