What: A fast and effective test for detecting the potentially deadly strain of bacteria known as E. coli 0157:H7 has been developed by researchers at the University of California, Davis. This is the same bacterium that in 1993 resulted in the deaths of four children who ate under-cooked hamburgers from a fast-food restaurant in the Pacific Northwest. In recent months, the same food-borne bacterium sickened more than 9,000 people in Japan, causing 11 deaths. The researchers will demonstrate the new testing technology. When: Tuesday, Oct. 22, at 1 p.m. Where: 207A Everson Hall, UC Davis Visuals: Researchers will be demonstrating the new test on hamburger, as it might be used in meat processing. Background: E. coli 0157:H7 is estimated to cause 10,000 to 20,000 cases of infection in the United States annually, according to the federal Centers for Disease Control and Prevention. There are hundreds of strains of the bacterium Escherichia coli, most of which are harmless and live in the intestines of healthy humans and animals. E. coli 0157:H7, however, causes infections in people that often lead to bloody diarrhea and occasionally to kidney failure. Preschool children and the elderly are at the greatest risk of serious complications.
