Eliminating doo-doos on those dirty hands

WASHINGTON – New light-scanning technology borrowed from the slaughterhouse promises to help hospital workers, restaurant employees – one day, even kids – make sure that hand washing zaps some germs that can carry deadly illnesses.

A device the size of an electric hand dryer detects fecal contamination and pinpoints on a digital display where on a person’s hands more scrubbing is needed. eMerge Interactive Inc., a struggling technology company in Sebastian, Florida, is hoping to tweak light scanners it already sells to beef plants to detect the same kinds of nasty germs on humans.The blue-light scanners could dramatically improve hygiene among employees who forget to wash their hands after bathroom breaks.This practice is a leading cause of food poisoning that afflicts tens of millions of Americans every year.Studies show people typically fail to scrub around fingernails and between fingers adequately.The government recommends people wash their hands for at least 20 seconds; researchers find many people do not even use soap.”People are not good at handwashing,” said Janet Anderson, a nutritionist at Utah State University.”We find that unless sinks are very close to where people are handling food, they don’t wash their hands well.”eMerge, which demonstrated an early prototype for The Associated Press, said its first clean-hand scanners could go on sale as early as year’s end to restaurants, nursing homes, hospitals and day-care centres.Using identification cards, the devices can even record which employees scrubbed acceptably and which ones still have dirty hands.”Being able to tell whether there’s fecal matter is a major improvement,” said Jim Mann, executive director of The Handwashing Leadership Forum, a group in Illinois that studies food-borne outbreaks.”Nobody wants to have doo-doo on their burger,” said Jacob Petrich, a biophysical chemist at Iowa State University who invented the meat-scanning technology with two scientists, Thomas A. Casey and Mark A. Rasmussen, at the Agriculture Department.- Nampa-ReuterseMerge Interactive Inc., a struggling technology company in Sebastian, Florida, is hoping to tweak light scanners it already sells to beef plants to detect the same kinds of nasty germs on humans.The blue-light scanners could dramatically improve hygiene among employees who forget to wash their hands after bathroom breaks.This practice is a leading cause of food poisoning that afflicts tens of millions of Americans every year.Studies show people typically fail to scrub around fingernails and between fingers adequately.The government recommends people wash their hands for at least 20 seconds; researchers find many people do not even use soap.”People are not good at handwashing,” said Janet Anderson, a nutritionist at Utah State University.”We find that unless sinks are very close to where people are handling food, they don’t wash their hands well.”eMerge, which demonstrated an early prototype for The Associated Press, said its first clean-hand scanners could go on sale as early as year’s end to restaurants, nursing homes, hospitals and day-care centres.Using identification cards, the devices can even record which employees scrubbed acceptably and which ones still have dirty hands.”Being able to tell whether there’s fecal matter is a major improvement,” said Jim Mann, executive director of The Handwashing Leadership Forum, a group in Illinois that studies food-borne outbreaks.”Nobody wants to have doo-doo on their burger,” said Jacob Petrich, a biophysical chemist at Iowa State University who invented the meat-scanning technology with two scientists, Thomas A.
