Computer mice are the dirtiest office desk items, carrying more than three times the amount of germs as the average toilet seat.
A study into office hygiene found keyboards were the second grubbiest item ahead of office phones because of the trend for eating “al desk” – at office desks – while continuing to work.
Researchers found the trend was making offices less hygienic and was exposing workers to harmful germs.
Hygiene specialists Initial swabbed 158 items from 40 desks at three offices and compared the results with data from toilets in other buildings.
They found that four in ten desks harboured at least one item with very high levels of bacteria which posed a risk to health.
The results also revealed that average levels of bacteria on male office workers’ desks were more than 40 percent higher than on females’ desks.
