The typical mobile phone can harbour up to 18 times more bacteria than the average toilet handle, it has been found, after hygiene experts working for consumer guide Which? tested a selection of 30 mobile phones to see how dirty they were.
They found seven were covered in high levels of environmental bacteria which could act as a breeding ground for other bugs. 1 in 7 even harboured faecal coliforms and could have given any user a serious stomach upset.
There are approximately 15 million mobiles in the UK currently.
