Hand Washing Is Up in Public Restrooms in U.S. Every few years, two groups do a study of how many Americans wash their hands after using the toilet. These groups are the American Society for Microbiology and the American Cleaning Institute, formerly the Soup and Detergent Association. There was good news in the latest study. Researchers found that 85% of adults washed their hands in public restrooms last month. That was the most yet since the studies began in 1996. Researchers visited restrooms at a baseball park in Atlanta and a science museum and aquarium in Chicago. They also visited two train stations in York city and a large farmers market in San Francisco. In all, they observed about 6000 adults. The researches found that 77% of men and 93% woman washed their hands. That was up from 66% of a man and 88% of woman in the last study three years ago. The lowest rate of hand washing among men was that at a Turner Field, home of the Atlanta Braves baseball team. Only 65% of men washed their hands, compared to all but 2% of women. Chicago and San Francisco had the most hand washers – 89% of adults. Atlanta followed at 82%. New York had the lowest rate, at 79% of the adults observed at Grand Central station and Penn Station. The findings of the observational study conflicted with the findings of a separate telephone survey of about 1000 people. 96% of them said they always wash their hands after using public restrooms. Almost 9 out of 10 also said they always wash after using the bathroom at home. Hand washing can help prevent the spread of many different infections. To clean your hands well, wet the first and rub in soap for at least 20 seconds, including the fingers and under the nails. Then rinse under running water. In a public restroom, if you dry your hands with a paper towel, you should also use the towel to shut of the water and open the door. Hand washing is also important when preparing food and after cleaning a baby's diaper. You should also wash if you cough or sneeze into your hands. If you use an alcohol–based product instead of soap or water, make sure it contains at least 60% alcohol. Choose the one that you think is the best answer for each sentence. 1.
