A new study found that mobile phones contain 18 times the amount of bacteria as a toilet handle, the Telegraph reports:

Swabs and analysis of 30 mobile handsets found that seven had high or warning levels of environmental bacteria. One contained such an intense concentration of bacteria, including faecal coliforms, that anyone using it could have faced a serious stomach upset.

According to hygiene expert Jim Francis “The levels of potentially harmful bacteria on one mobile were off the scale. That phone needs sterilizing.” The tests showed how easily bacteria could linger on the surface of a phone, which could be passed on to other people if they held the handset to look at photos or other applications.
