Office Study Reveals Top Germ Hotspots
Contributed by Chicopee
New research by leading international brand of professional cleaning materials Chicopee has revealed the germ hotspots in Britain’s offices.
COVID-19 and the long-term effects of the pandemic has meant that businesses are all becoming more conscious of keeping communal areas safe for workers returning to the office. With many office workers returning to the workplace, at least on a flexible basis over the past few months, it is important to understand the danger areas for harboring germs and bacteria.
The brand, which specializes in microfiber cloth that removes 99.99 percent of bacteria, swabbed1 the main touchpoints in offices to test for aerobic bacteria, yeast and mold. The swabs were then incubated and tested to find the number of colony-forming units per cm2, revealing the worst offending areas for high levels of viable bacterial and fungal cells.
The germ hotspots of the office as revealed by the study were:
1. Computer mouse (580 combined colony forming units)
2. Kettle (336.6 combined colony forming units)
3. Fridge (295 combined colony forming units)
4. Laptop (264.8 combined colony forming units)
5. Bathroom lock (188 combined colony forming units)
6. Hand sanitizer bottle (175.5 combined colony forming units)
7. Printer (100.5 combined colony forming units)
8. Light switch (99 combined colony forming units)
9. Desk phone (96.5 combined colony forming units)
10. Kitchen cupboard (67.9 combined colony forming units)
The research found that the computer mouse was the dirtiest touchpoint in the office, ranking the highest of all the tested areas for bacteria colonies per agar — a staggering 250. 225 yeast colonies were also identified on the mouse surface, almost double the level of all other areas tested.
The kettle was the second dirtiest area within the office environment, due to the high levels of mold present on the surface and 200 colonies of yeast, followed by the fridge.
On the fridge, a staggering 130 colonies of bacteria were present on the swab sample, making it one of the most infectious areas in the workplace.
Other key areas which saw a high level of germs and bacteria included a laptop, bathroom lock and hand sanitizer bottle. The hand sanitizer bottle came top for the level of mold formation following the incubation period.
Interestingly, the toilet seat did not even make the top ten germ hotspots, with the toilet swab actually producing 11 times less combined colony forming units than a computer mouse.
Potentially the most common touch point in the office is the desk but compared to other areas, the desk swab actually produced the lowest amount of combined colony forming units, 4.8 in total. That’s a staggering 120 times less bacteria, yeast and mold than found on the computer mouse and 36 times less than the hand sanitizer bottle.
Overall, across the 13 touch points tested, the swabs found a total of 1,644 colonies of yeast and bacteria.
