One in six cellphones in Britain may be contaminated with fecal matter that can spread E. coli, likely because so many people don't wash their hands properly after using the toilet, according to  researchers at the London School of Hygiene&Tropical Medicine and Queen Mary, University of London.

The findings also suggest that many people lie about their hygiene habits. The study authors went to 12 cities and collected 390 samples from the cellphones and hands of volunteers, who were also asked about their hand-washing habits.
