DuPont Qualicon BAX® System Vibrio Assay Certified by AOAC

The AOAC Research Institute (AOAC-RI) in Gaithersburg, Md., has recently certified the BAX® system from DuPont Qualicon as a Performance TestedSM Method for detecting Vibrio in many types of seafood.

Validation studies compared the BAX® system 20-hour assay to traditional culture methods, which typically take 3-5 days for results. Tested on shrimp, tuna, oysters and scallops, the BAX® system reliably detected three pathogenic species of Vibrio—V. cholerae, V. parahaemolyticus and V. vulnificus – even at very low levels.

“The BAX® system now offers a suite of assays certified by AOAC-RI for detecting the most common pathogens of concern to the seafood industry,” said Michael Chong, Asia Pacific business manager – DuPont Qualicon. “Single-platform testing and fast results are a winning combination for customers who want to optimize inventory, reduce storage costs, and ship quickly.”

Food processing companies around the world rely on the BAX® system from DuPont Qualicon to detect pathogens or other organisms in raw ingredients, finished products and environmental samples.  The automated system uses leading-edge technology, including PCR assays, tableted reagents and optimized media to detect Salmonella, Listeria, E. coli O157:H7, Campylobacter, Staphylococcus aureus and more. 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.  DuPont Qualicon also markets the RiboPrinter® system, an automated method for identifying bacteria and pinpointing the contamination source.
