BAX® System 8-Hour Assay for Detecting Listeria Certified by AOAC-RI

A new BAX® system assay from DuPont Nutrition & Health that uses innovative technology for rapid Listeria detection has been certified as Performance Tested^sm Method No. 030801 by the AOAC Research Institute (AOAC-RI) of Gaithersburg, Md.

Validation studies compared BAX® system performance to the standard culture method used by the U.S. Department of Agriculture Food Safety and Inspection Service. AOAC-RI found that the automated BAX® system performed significantly better than the culture method for detecting Listeria on stainless steel surfaces. Moreover, by using advanced technology called reverse-transcriptase polymerase chain reaction (RT-PCR) to jump-start the reaction, results are available just eight hours after sampling.

'When we introduced this application of RT-PCR to Listeria testing, we knew that it was exceptional in terms of speed and sensitivity,' said Kevin Huttman, president -- DuPont Nutrition & Health. 'We are very pleased to now offer the first assay of its kind that is certified by AOAC-RI.'

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, Campylobacter 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.
