US Government Study Concludes: You're Probably Washing Your Hands Wrong (cnn.com) 179

97% of us don't wash our hands properly, a new government study concludes. An anonymous reader quotes CNN: The study from the U.S. Department of Agriculture shows most consumers failed to wash their hands and rub with soap for 20 seconds. That's the amount of time recommended by the Centers for Disease Control and Prevention, which says that washing for shorter periods means fewer germs are removed. "Numerous" study participants also didn't dry their hands with a clean towel.

The study involved 383 people in six test kitchen facilities in the metro Raleigh-Durham area of North Carolina and in rural Smithfield, North Carolina, the USDA said... About half the time, participants spread bacteria to spice containers while preparing burgers, and 11% of the time, they spread bacteria to refrigerator handles... The results from the USDA's study indicate our hand-washing habits may be getting worse. A study done in 2013 by Michigan State University found only 5% of people washed their hands correctly....

A separate study released this month found 49 of 100 towels tested showed growth of bacteria normally found in or on the human body.

CNN helpfully provides the proper method for handwashing. (Wet hands, lather them with soap -- between fingers and under fingernails -- and then scrub for at least 20 seconds.) They recommend singing the alphabet song once or "Happy Birthday" twice.

Just in America, foodborne illnesses sicken 48 million people each year, sending 128,000 to hospitals and resulting in 3,000 deaths.

    Our environments should be clean, not sterile. We have defenses, evolved over millions of years, in place specifically for handling these things. Unless you're immuno-compromised, going into surgery, or work in a restaurant, there's no reason to not allow your immune system to do its job.

      Washing hands does not make the world sterile. It makes sure that the tools you were born with are clean enough to rub your eyes, scratch your skin or put food in your mouth.

        Washing your hands is good. The practice they are recommending is what is recommended for medical professionals on the job...and not usually followed by them.

        There are good reasons to NOT wash your hands that thoroughly. Doing so is likely to damage the skin, leading to rough and cracked skin that literally cannot be washed thoroughly. Most medical practices now recognize this, and I believe that the use of thin plastic gloves rather than depending on excessive hand washing is now uniformly the practice.

    • The point isn't that you should worry about regular bacteria, it is that if they had something contagious on their hands it would spread by the same amount as the regular harmless stuff. They're not going to infect volunteers with salmonella to do the test!

One easy way to reduce the spread of disease, give people sickleave completely independent from their holiday leave, and tell them to stay the heck away from others.

        Are you a medical professional? Do you know how then sanitize their hands? Apparently not.

        First you wash your hands using water and soap THEN apply alcohol based desinfectant (not gel). Alcohol gel is the household product companies sell to ordinary customers. Nothing wrong with that but not what they use in hospitals etc.

        Also, if your hands are dirty, adding alcohol gel and smearing the dirt around will not make them clean, that is why you should wash your hands first. But sure, if you have no way of clean

Just don't tear it off until they're clean. If your hands are still wet, use that towel to cover the dispensing handle while you get some more. Then throw the final towel away after opening the door with it. If they don't put a trash can by the door, throw it neatly in the corner. They'll figure out soon enough.
