Gotcha! science strikes again. Bacteria can be found. And people lie.

One in six mobile phones in Britain is contaminated with fecal matter, according to new research released ahead of Global Handwashing Day.

Experts say the most likely reason for the potentially harmful bacteria festering on so many gadgets is people failing to wash their hands properly with soap after going to the toilet.

The findings of the UK-wide study by scientists from the London School of Hygiene & Tropical Medicine and Queen Mary, University of London also reveal a tendency among Britons to lie about their hygiene habits.

Although 95% of people said they washed their hands with soap where possible, 92% of phones and 82% of hands had bacteria on them. Worryingly, 16% of hands and 16% of phones were found to harbor E. coli.
