BAX® System Real-Time PCR Assay Certified by AOAC-RI


A BAX® system assay from DuPont Qualicon that uses real-time PCR to detect Staphylococcus aureus (S. aureus) has been certified as Performance Testedsm Method No. 120701 by the AOAC Research Institute in Gaithersburg, Md.

The AOAC Research Institute is a non-profit international, scientific organization that provides an independent third-party review of test kit performance claims. Food processors who require an AOAC-approved testing method now can use the BAX® system assay for quick and reliable detection of S. aureus, a foodborne species that has been implicated in human illness. As validated on powdered infant formula, the assay’s sensitivity can detect one viable cell in a gram of product. For quality testing in ground beef and soy protein isolates, threshold values also can be determined by modifying the sample preparation protocol. Results are comparable to traditional culture methods but available next-day, with less than 90 minutes processing time.

“Because even small amounts of toxin from S. aureus can cause food poisoning, processors count on the BAX® system for accurate, reliable detection,” said Kevin Huttman, president, DuPont Qualicon. “This approval from AOAC adds value to the BAX® system line of certified products, all designed to help food companies protect their products and their brands.”

Food businesses around the world rely on the BAX® system to detect pathogens or other organisms in raw ingredients, finished products and environmental samples. With certifications and regulatory approvals in the Americas, Asia and Europe, the BAX® system is recognized globally as the most advanced pathogen testing system available to food companies.
