DuPont Qualicon BAX® System for Detecting Listeria Receives AOAC-RI Certification
Today DuPont Qualicon announced that it’s BAX® system for detecting Listeria has been certified as Performance Testedsm Method No. 030502 by the AOAC Research Institute 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, which requires a 48-hour dual enrichment and manual plating. AOAC-RI found that the automated BAX® system performed as well as the culture method for detecting Listeria species on environmental surfaces such as plastic, ceramic, rubber, concrete, wood, cast iron and air filter material. Moreover, proprietary BAX® system media combines a single enrichment step with shorter incubation times, so that results are available about 30-33 hours after sampling.
“Labs that need third-party endorsement have been waiting for this approval,” said Kevin Huttman, president of DuPont Qualicon. “Now they can start saving time and money with the simplified enrichment and next-day results of the BAX® system.”
The BAX® detection system is an innovative DNA-based technology for screening raw ingredients, finished products and environmental samples for pathogens or other organisms. The BAX® system provides polymerase chain reaction (PCR) assays to detect Salmonella, Listeria monocytogenes, Listeria species, E. coli O157:H7 and Enterobacter sakazakii. Optimized media is also available for some assays.
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, visit www.qualicon.com
