Stomach upsets caused by bacteria from dirty computer keyboards.
The phrase “qwerty tummy” is in the news once more, following revelations from the Royal Society of Chemistry that mouse droppings are being found on office keyboards. Paul Sims wrote in The Daily Mail:
A spokesman for the RSC said: “There is evidence that mice run along a computer keyboard, pressing down on the keys to get at food crumbs left by people snacking while working.
“That is why it is important to wash your hands before eating food.”
Computer keyboards have long been blamed for causing health problems. Research conducted by Which? in 2008 found they can harbour more harmful bacteria than a lavatory seat.
Many users, they said, are at risk of becoming ill with stomach bugs dubbed “qwerty tummy” after the first six letters on a keyboard.
