A study by Initial Washroom Hygiene claims that microbiological activity is 18 percent higher in ‘hot desking’ environment. The firm claims that these findings suggest that having germs from different people on the surface of shared desks, computer mice and other equipment, means these workstations are typically home to more bacteria. The swabbing study was conducted using one company of over 100 employees with a fixed-desk environment. The same company then moved to a hot-desking environment, and the study was repeated in the same manner four months later. Experts from used an ATP bioluminescence reader to measure the microbiological concentration of various items on 40 different workstations, to determine what levels of bacteria these surfaces were harbouring. On average, the readings in the hot-desking office were 18 percent higher than those in the fixed-desk office. The use of communal computer mice in the hot-desk scenario was a key contributor to the difference in hygiene levels. Shared mice in the hot-desking environment had a 41 percent higher microbiological reading compared to readings taken from the computer mice on the fixed-desks.
