For whatever reason, a mobile phone retailer called Dial-a-Phone did a study on how clean the average cell phones are. The study shows there's more bacteria on the average cell phones than the average door handle, keyboard, and bottom of a shoe or even a toilet seat. Skin bacteria such as staphylococcus aureus are found on the tested objects, however shoe shows more backteria from soil and air.
Joanne Verran, Professor of Microbiology at Manchester Metropolitan University comments: "Mobile phones, like many everyday objects such a telephones and computer keyboards, harbor bacteria. However, being 'mobile', they are stored in bags or pockets, are handled frequently, and held close to the face. In other words, they come into contact with more parts of our body and a wider range of bacteria than toilet seats!"
