DuPont and U.S. Department of Agriculture Collaborate on New Test for Hard to Detect Foodborne Pathogens

Tuesday 3 August 2010

DuPont and the U.S. Department of Agriculture (USDA) have agreed to collaborate on the development of a new test for detecting hard-to-identify strains of toxin-producing E. coli that are not currently regulated and have been causing increased instances of food contamination and illness.
DuPont was among the first to develop tests for E. coli O157:H7, the type of shiga toxin-producing E. coli (STEC) most frequently associated with global food contamination outbreaks. The USDA Food Safety and Inspection Service uses the DuPont™ BAX® System to monitor for this pathogen.

In recent years, other types of STEC have been identified as agents of foodborne illness, and these are a growing concern in the U.S., Europe, Japan and food safety agencies worldwide. The Agriculture Research Service of the USDA (USDA ARS) will collaborate with DuPont Qualicon to develop an effective test for the “Big 6” non-O157 STEC pathogens in food, and also will expand the diagnostic tools offered for use in the DuPont™ BAX® System.

“The USDA continually looks for opportunities to collaborate in ways that will expedite research to assist regulatory agencies and move technologies into the marketplace,” said Pina Fratamico, USDA ARS research microbiologist. “This collaborative project to develop a discriminating STEC test is a good fit with our mission.”
