The term qwerty tummy first appeared in 2008, coined by consumer group Which? in the context of a study on office hygiene. Scientific experts swabbed 33 computer keyboards for food poisoning bugs such as e-coli and staphylococcus, comparing the results to those found on lavatory seats and door handles. The findings, which experts claimed were typical of offices all over Britain, were shocking, with some keyboards harbouring five times more bacteria than lavatory seats. The currently common practice of hotdesking – where office workers sit at different desks every week (and so each keyboard is used by a range of people) – is also thought to exacerbate the risk of qwerty tummy.
