According to Dr Charles Gerba, a professor of environmental microbiology from the University of Arizona, the communal kitchen sponge that is rarely changed is a key culprit in the development of bacteria. So, people should now think twice before making a cup of tea or coffee in their office kitchens.
The recent research has reported that around 90 per cent of communal coffee mugs are coated with germs, where 20 percent of those mugs carry fecal matter actually. Dr Gerba wrote, “Coliform bacteria were present on 20 per cent of the coffee cups before and 100 per cent of the coffee cups after wiping with a dish cloth or sponge. No E. coli was found on cups prior to wiping. However, 20 per cent of coffee cups were positive for E. coli after wiping.”
Dr Gerba suggests that, people should avoid drinking tea or coffee in their co-workers’ mugs that may contain faecal bacteria and either one should take his mug to home and put it in dishwasher or should invest in an office cup washer.
Also the researchers related to the study have identified the smartphones with a disgusting level of bacteria. A study conducted by the London School of Hygiene and Tropical Medicine in 2011, found a ratio of contaminated mobile phones with faecal matter as one in six phones in the United States.
Dr Scott Kelley from California University led a subsequent study in 2012, which disclosed that, men’s offices had remarkably more bacteria than women’s offices. Dr Kelley stated that, “Humans are spending an increasing amount of time indoors, yet we know little about the diversity of bacteria and viruses where we live, work and play.”
