Thirty-three percent didn’t use soap, and 10 percent didn’t wash their hands at all, according to the study, based on Michigan State University researchers’ observations of more than 3,700 people in a college town’s public restrooms.
“These findings were surprising to us because past research suggested that proper hand washing is occurring at a much higher rate,” lead investigator Carl Borchgrevink, an associate professor of hospitality business, said in a university news release.
