so a couple of years ago i wrote a post about how farcical hand sanitizers were as nobody could explain how the damn things work and what good they were?
seems like two years later, they’re more and more pervasive and they’re still full of absolutely no benefit to us. slate has a fairly in-depth article on whether or not they help protect us from things like the flu and H1N1. seems like for the most part, soap and water works just as well.
scientists were for some reason surprised that giving free hand sanitizers (and, in one case, even clorox wipes) to families and schools failed to cut down on infections.
Our homes and workplaces, we’re told, are trying to kill us. Recently, a University of Arizona microbiologist named Charles Gerba, author of hundreds of scientific papers about household microbes, gave a terrifying lecture at the offices of the Food and Drug Administration. Gerba—who, incidentally, has a child with the middle name Escherichia—that’s what the “E” in E. coli stands for—explained that a kitchen sponge and sink are home to thousands of times more bacteria than a toilet seat. Plus, 10 percent of household dishrags contain salmonella. After playing with other children, toddlers have more fecal bacteria on their hands than does a person exiting a public toilet stall. Those toilets, by the way, aerosolize so many droplets with each flush that Gerba compares their dispersion to “the Fourth of July.” And every public swimming pool he’s ever tested has contained disease-causing viruses.
In response to these kinds of data, more than 700 products promise to help consumers kill bacteria, molds, and viruses in their homes and workplaces, from ultraviolet lights meant to kill toothbrush bacteria, to dishwashers that superheat silverware, to specially treated doormats. Three-quarters of all Americans use six or more antimicrobial products each day.
