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

A new BAX® system assay from DuPont Qualicon that uses real-time PCR to detect Campylobacter has been certified as Performance Testedsm Method No. 040702 by the AOAC Research Institute in Gaithersburg, MD.

Validation studies on enriched samples of ready-to-eat turkey and chicken carcass rinses compared BAX® system performance to the ISO 10272-1:2006 culture method.    AOAC-RI found that qualitative results with the BAX® system demonstrated sensitivity that was equivalent to the reference method, with 99 percent specificity.

The BAX® system real-time PCR assay for Campylobacter, developed in alliance with Applied Biosystems, detects and differentiates three foodborne species of Campylobacter (C. jejuni, C. coli and C. lari) in the same sample. With less than 90 minutes processing time, the BAX® system delivers next-day results on enriched samples.

“This new assay offers poultry customers a fast, sensitive and highly accurate method for detecting pathogenic Campylobacter” said Kevin Huttman, president of DuPont Qualicon.   “Adding this AOAC certification to our portfolio of certified products provides even greater value to food businesses that choose the BAX® system as their preferred diagnostic method.”

Food processing companies around the world rely on the BAX® system to detect pathogens or other organisms in raw ingredients, finished products and environmental samples.   The automated system uses leading-edge technology, including polymerase chain reaction (PCR) assays, tableted reagents and optimized media, to also detect Salmonella, Listeria, E. coli O157:H7, Enterobacter sakazakii and Staphylococcus aureus.  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 patented RiboPrinter® system, the world’s only automated DNA fingerprinting instrument to track and trend bacterial contamination in pharmaceuticals, personal care products and food.  For more information and product photos, visit .
