[转帖]Technology may make food safer
<p>WEST LAFAYETTE, Ind., Oct. 6 (UPI) -- Inexpensive technologies may be able to help prevent future food-borne illness, such as the E. coli found in bagged spinach, suggest U.S. researchers. </p><p>One method uses a laser to detect and identify many types of bacteria, and is about three times faster and one-tenth as expensive as current technology, according to Richard Linton, a professor of food science at Purdue University. </p><p>A second innovation uses chlorine dioxide gas to kill pathogens on produce, fresh fruits and vegetables. This would be a large step up from current technologies, which mainly involve washing and scrubbing, and cannot completely rid a product of a pathogen like E. coli, according to Linton. </p><p>"We can use the laser technology to detect problems more quickly, determine exactly what the pathogen is and where it came from," Linton said. "As for using this gas as a disinfectant, I would say that in my 13 years of doing research, it is 10,000 to 100,000 times more effective than any process I have seen."</p><p>URL FROM:http://www.upi.com/ConsumerHealthDaily/view.php?StoryID=20061006-050524-8010r</p>
