Researchers at the London School of Hygiene and Tropical Medicine and Queen Mary, University of London took nearly 400 samples from mobile phones and hands in 12 British cities.
They found 16% of phones and 16% of hands harboured E. coli (Escherichia coli), bacteria which inhabit the human intestines.
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%).
"We found the further north we went the more hands and phones
were likely to be contaminated. It could be the bugs survive better in
colder and wetter conditions or it might be that people wash their
hands less."
