5. Soap Dispensers
About 25 percent of public restroom dispensers are contaminated with fecal bacteria. Soap that harbors bacteria may seem ironic, but that's exactly what a University of Arizona study found. "Most of these containers are never cleaned, so bacteria grow as the soap scum builds up," says microbiologist Charles Gerba, Ph.D., who directed the study. "And the bottoms are touched by dirty hands, so there's a continuous culture feeding millions of bacteria." Be sure to scrub your hands thoroughly with plenty of hot water for 15 to 20 seconds — and if you happen to have an alcohol-based hand sanitizer, use that, too.
