Fast, accurate testing results are critical for delivering safer food products to consumers and more profitable growth for food companies. That’s why at DuPont, our food safety science is focused on continually developing state-of-the-art technologies that are easy, effective and efficient. In fact, for more than 16 years, we have been revolutionizing food safety.

DuPont was the first company to apply PCR technology to commercial food testing with rapid, DNA-based assays for Salmonella, Escherichia coli O157:H7 and Listeria monocytogenes. Our use of automated PCR processing with tableted rather than liquid reagents created a dramatic increase in speed and consistency—helping to usher in a new era of easy-to-use testing methodology.

Meeting a Global Need
Leading food companies and government testing labs around the world have come to rely on the genetics-based BAX® System to quickly and accurately detect pathogens such as Salmonella, E. coli O157:H7, L. monocytogenes, Campylobacter, Vibrio and more. The U.S. Department of Agriculture Food Safety and Inspection Service (USDA FSIS) has adopted the BAX® System for meat and poultry testing, and government testing agencies in Brazil, Canada, China, Russia and other parts of the world have validated it as an approved testing method to help protect their food supply and their citizens.

The BAX® System has been certified by independent authorities such as AOAC, NordVal and the French Association of Normalization. What’s more, it has been included in the Emergency Response Validation program of the AOAC Research Institute, a program designed to respond immediately to food contamination crises.

Delivering Innovations Year after Year
While we’re proud to have been a part of food safety history, we’re always looking ahead to provide the next breakthrough with technological advances and new assays that make food safety testing faster and more convenient without sacrificing accuracy.

For example, as a result of collaborative research projects with the USDA Agricultural Research Service, we have developed a portfolio of BAX® System PCR assays to address E. coli testing needs. Our real-time test for E. coli O157:H7 detects all known E. coli O157:H7, including rough strains, with same-day results. Additionally, our real-time STEC suite is closely aligned with the FSIS method—providing a screen to quickly clear stx/eae-negative samples and panels to identify the “Top Six” pathogenic non-O157 serogroups in potential positives.
