DuPont develops new BAX System assay

DuPont develops new BAX System assay
Next-generation test for Listeria monocytogenes combines shorter, simpler sample preparation and faster real-time processing, without sacrificing accuracy or reliability.

Food processors and service labs who need a fast, accurate test for Listeria monocytogenes can now use the latest DuPont™ BAX® System assay from DuPont Nutrition & Health to help support food safety and quality standards. This next-generation test—which combines shorter, simpler sample preparation and faster real-time processing, without sacrificing accuracy or reliability—will be introduced at the International Association for Food Protection (IAFP) annual meeting in Indianapolis Aug. 3 to 6.

The DuPont BAX System Real-Time PCR Assay for L. monocytogenes is a quick and reliable method for detecting L. monocytogenes in a variety of products and has been validated on frankfurters, cooked shrimp, spinach, queso fresco and environmental surfaces. Furthermore, the assay provides additional flexibility by allowing customers to test for L. monocytogenes, Listeria spp. and Salmonella in the same batch, with results for all organisms in a little over an hour.  

“Listeria monocytogenes is widely recognized as an important cause of human foodborne illness, particularly for persons with heightened susceptibility,” said Rob McPheeters, diagnostics leader at DuPont Nutrition & Health. “With this new real-time PCR assay, we are reconfirming our commitment to helping food producers and manufacturers detect this pathogen with speed, accuracy and reliability to provide the best value in science-based solutions.”

In addition, this new assay completes the BAX System portfolio of real-time PCR assays for the common U.S. pathogens, which allow for superior specificity, shorter processing time and faster results. With this offering, DuPont Nutrition & Health can provide a complete testing solution for Salmonella, E. coli O157:H7, non-O157 STEC, Genus Listeria, L. monocytogenes, Campylobacter and more on a single, easy-to-use platform.

“Real-time PCR technology is a reliable and trusted method for rapid pathogen detection in food,” said Shannon Bullard, Diagnostics global product manager, DuPont Nutrition & Health. “We are proud to offer a complete real-time testing solution for all the common pathogen testing needs with the DuPont BAX System, including the accuracy, reliability and support you expect from DuPont.”
