Handwashing is simple. Science says otherwise. Despite endless statements to just wash hands to be safe — in the kitchen, in food service, at the petting zoo- little research has been done to quantify what actually works when it comes to hand washing… Dr. Donald Schaffner, a professor of food safety at Rutgers University, and colleagues, have attempted to add some science to the discussion… "Many people seem to have strongly held opinions about handwashing, says Schaffner, "but the research base for those opinions is lacking. Our research begins to dispels some popular beliefs about hand washing."… The researchers showed that even a minimal handwash (5 seconds, no soap) can remove about 90 per cent of bacteria on hands.
