This filthy fact was unearthed after 30 mobile phones were tested for germs by product-testing charity, Which?, seven of which contained “dangerous levels” of “environmental bacteria”.
The most unhygienic of the phone had enough faecal matter to give someone a serious case of diarrohea.
It carried 39 times the acceptable level of enterobacteria, a family of bacteria that includes Salmonella, found in the lower intestines of humans and animals.
Hygene expert Jim Francis, who performed the tests, said: "The levels of potentially harmful bacteria on one mobile were off the scale.
“That phone needs sterilizing."
These findings relate directly to a recent survey by BM Savings that found mobile phones to be an inseparable companion of Britons.
Martyn Hocking, editor of Which? magazine said: “It’s a worrying thought that people could be putting their health at risk with bacteria-ridden handsets.
“It’s time to give those mobiles a good clean.”
