Hand washing in public restrooms increased after last year’s swine flu pandemic made germ-killing a public health priority, a new study found. Travelers at New York’s bustling Penn Station still forgot to scrub.
About 85 percent of adult bathroom-goers washed their hands, an increase from 77 percent in 2007, according to a study of six public facilities in four U.S. cities. Penn Station was the least hygienic of the six, with 21 percent of people skipping the sink. Grand Central Station fared little better, with 19 percent unwashed, and was the only site where the numbers declined.
