Bathroom Hand Dryers May Leave Your Hands With Bacteria

Hand dryers may leave your hands significantly more dirty than before, according to a new study. The journal of Applied and Environmental Microbiology, found that plates exposed to 30 seconds of a bathroom hand dryer gained at least 18-60 colonies of bacteria, while plates exposed to bathroom air for two minutes had fewer than one. The authors concluded that the “results indicate that many kinds of bacteria, including potential pathogens and spores, can be deposited on hands exposed to bathroom hand dryers, and that spores could be dispersed throughout buildings. Still the study’s authors, who found that the nozzle of the dryers had minimal bacterial levels, said that more evidence was needed to determine if the dryers were bacteria harbours themselves or simple blew large amounts of contaminated air. The study noted that hand dryers with certain types of filters, called HEPA filters, could reduce the bacteria…..Ed
