The researchers said they placed the plates under the dryers for about 30 seconds and found “between 18 and 60 different colonies of bacteria on each plate.”
"These 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 and deposited on hands by hand dryers," the study said.
