There is no delicate way to put it.  British researchers say one in six cell phones, and the hands that handle them, have fecal matter on them. The study analyzed nearly 800 samples in a dozen cities in the the U.K. and found that 16-percent of mobile phones and their owners' hands were contaminated with E. coli.  That's the potentially illness-causing bacteria that comes from fecal matter.  Researchers say the likely reason is that some people don't wash their hands with soap after they use the toilet.
