New research reveals that one in six mobile phones in Britain is contaminated with faecal matter. 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 harbour E. coli, bacteria of a faecal origin. Harmful E. coli (Escherichia coli) is associated with stomach upsets and has been implicated in serious cases of food poisoning such as the fatal O157 outbreak in Germany in June 2011.
The largest proportion of contaminated phones was in Birmingham (41%) while Londoners were caught with the highest proportion of E.coli present on hands (28%). However, actual levels of bacteria increased the further North the scientists went, the dirtiest city being Glasgow, where average bacterial levels on phones and hands were found to be 9 times higher than in Brighton, reinforcing a North and South divide. The scientists also found those who had bacteria on their hands were three times as likely to have bacteria on their phone.
Dr Ron Cutler, of Queen Mary, University of London, said: “Our analysis revealed some interesting results from around the UK. While some cities did much better than others, the fact that E. coli was present on phones and hands in every location shows this is a nationwide problem. People may claim they wash their hands regularly but the science shows otherwise.”
Faecal bacteria can survive on hands and surfaces for hours at a time, especially in warmer temperatures away from sunlight; it is easily transferred by touch to door handles, food and even mobile phones. From there, the germs can be picked up by other people. Every year, 3.5m children under the age of five are killed by pneumonia and diarrhoeal diseases – and the simple action of washing hands with soap is one of the most effective ways of preventing these illnesses. In developed countries, handwashing with soap helps to prevent the spread of viral infections, such as norovirus, rotavirus and influenza.
Global Handwashing Day – which is held on October 15 every year – aims to transform the action of washing hands with soap into an automatic behaviour, deeply set in our daily lives. Initiatives and events to promote the practice in homes, schools, workplaces and communities are held worldwide.
The UK Global Handwashing coalition involves GlaxoSmithKline, Initial Washroom Solutions, London School of Hygiene & Tropical Medicine, Sanofi Pasteur MSD, School Councils UK, Queen Mary, University of London, The Ideas Foundation and Wellcome Trust.
