Your computer keyboard could be dirtier than your toilet.

A study from Which? Computing in England has found some keyboards contained more bacteria than the average toilet seat.

Researchers took swabs from 30 office keyboards and uncovered a cocktail of bugs that can cause infection and illness.

Two contained staphylococcus aureus, which can lead to skin infections and food poisoning.

In one case, a microbiologist recommended that a keyboard should be removed as a precaution after finding bacteria readings "off the scale."

Microbiologist James Francis of Kingmoor Technological Services in Carlisle, England, said the contamination is largely due to a lack of proper lunch breaks.

"More and more people are eating at their desks and are transferring from hand to mouth all the time,” he said.” That is making things worse.”

"Telephones are also a problem. We have found a lot of pathogenic disease-causing bacteria on telephones in hotel rooms, for example. It is often down to common sense. If something looks grimy and horrible there is a good chance it is."

Jaclyn Clarabut, assistant editor at Which? Computing, told Sky News Online that people have to take responsibility for their office environment.

"People should use alcohol wipes to really get rid of the germs,” Clarabut said. “The best thing is to tip keyboards upside down and watch the crumbs fall out. Once that's gone, the bacteria stops growing.

"If people don't clean their keyboards regularly, they might as well eat lunch in the toilet."
