DuPont Qualicon BAX® System Adopted by USDA Food Safety and Inspection Service to Detect Salmonella in Raw Food Products

The BAX® system, a genetics-based screening method developed by DuPont Qualicon, has been adopted by the United States Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS) to detect Salmonella in food plants that process raw meat and poultry.

“This measure increases efficiency in detecting pathogens and saves valuable agency time and resources,” said FSIS Administrator Dr. Garry L. McKee. “This is another tool that will help us protect public health.”

An evaluation of more than 300 random meat and poultry samples demonstrated that the BAX® system was as accurate as the current method used by FSIS, but reduced reporting time of negative results by one to two days. FSIS has already adopted the BAX® system for detecting Salmonella in ready-to eat foods and for detecting Listeria monocytogenes in meat and poultry. The agency also plans to evaluate the BAX® system for detecting E. coli O157:H7 this year.

“Once again, the BAX® system has met high government standards for performance,” said Kevin Huttman, president of DuPont Qualicon. “In evaluations of the best science-based tools for monitoring food safety, the BAX® system consistently stands out as the logical choice.”

Eating food that is contaminated with Salmonella can result in salmonellosis, a serious, sometimes fatal, infection. The Centers for Disease Control estimate 40,000 cases of salmonellosis are reported in the United States each year.

The BAX® system uses advanced molecular technology to detect target bacteria in raw ingredients, finished food products and environmental samples. In addition to Salmonella, assays are also available for detecting Listeria monocytogenes, Listeria genus, E. coli O157:H7 and Enterobacter sakazakii. The automated system is user-friendly and fits easily onto a laboratory bench top. Introduced in November 2000, hundreds of automated BAX® systems are already in use by governments, food companies and laboratories around the world.

DuPont Qualicon also markets the patented RiboPrinter® system, the world’s only automated DNA fingerprinting instrument, which can be used to rapidly pinpoint sources of bacteria in pharmaceuticals, personal care products and food. For more information on these products, please visit on the web.
