Some hands 'like dirty toilets': study

More than one in 10 people's hands are so contaminated with faecal organisms that the levels of bacteria detected were equal to what you would expect to find in a dirty toilet bowl, a study suggests.

Out of the samples taken, 11 per cent of hands, eight per cent of bank cards and six per cent of bank notes showed this form of gross contamination, the study released on Monday found.

In Britain, one in 10 bank cards (10 per cent) and one in seven notes (14 per cent) were found to be contaminated with some faecal organisms, the research, carried out at Queen Mary, University of London and the London School of Hygiene & Tropical Medicine, showed.

More than a quarter (26 per cent) of hands sampled showed traces of faecal contamination including bacteria such as E.coli, the study found.

The 272 participants who took part in the scientific study were also asked to fill out a questionnaire with the results revealing only 39 per cent of respondents washed their hands before eating.

The vast majority (91 per cent) of respondents also stated that they washed their hands after using the toilet, although the levels of faecal organisms contaminating the cards and currency suggested otherwise, researchers said.

Washing hands with soap can reduce diarrhoeal infections by up to 42 per cent but only 69 per cent of people reported doing this whenever possible.

Dr Ron Cutler, who led the research at Queen Mary, said: "Our analysis revealed that by handling cards and money each day we are coming into contact with some potential pathogens revealing faecal contamination including E. coli and Staphylococci.

"People may tell us they wash their hands but the research shows us different, and highlights just how easily transferable these pathogens are, surviving on our money and cards."

Dr Val Curtis, from London School of Hygiene & Tropical Medicine, said: "Our research shows just how important handwashing is - the surprising levels of contamination that we found on everyday objects is a sign that people are forgetting to wash their hands after the toilet, one of the key moments for infection prevention."

Nick Wilcher, marketing manager of Radox, who funded the study to raise awareness of Global Handwashing Day, said: "Our research highlights just how much bacteria we are exposed to in our everyday lives, on objects such as money and cards".
