DuPont Qualicon BAX® System 24E Assays for Listeria Certified by AOAC

Two BAX® System assays from DuPont Qualicon have received certification from the AOAC Research Institute as next-day methods for detecting Listeria in food and environmental samples.

The BAX® System 24E Assays for detecting Listeria species, an indicator organism, and Listeria monocytogenes, a pathogen, were developed in collaboration with Oxoid, Ltd. Validation studies on hot dogs, spinach, cooked shrimp, queso fresco cheese and stainless steel showed that the BAX® System performed as well or better than traditional culture methods and with much quicker time to result.

“Coupled with the certification these assays have already received from AFNOR in Europe, this AOAC-RI validation provides customers with additional assurances of accuracy and reliability,” said Morgan Wallace, senior research microbiologist – DuPont Qualicon.

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 detect Salmonella, Listeria species, Listeria monocytogenes, E. coli O157:H7, Enterobacter sakazakii, Campylobacter, Staphylococcus aureus, Vibrio, yeast and mold.  With certifications and regulatory approvals in the Americas, Asia and Europe, the BAX® system is recognized globally as one of the most advanced pathogen testing systems available to food companies.
