Applied Markets Watch: DuPont Listeria Assay

Premium

DuPont said this week that its BAX System real-time PCR assay for Listeria species has been certified by the AOAC Research Institute as a Performance Tested Method.

The assay has been validated on frankfurters, cooked shrimp, spinach, queso fresco, and environmental surfaces using reference method media as well as proprietary media for a shorter, single-stage enrichment, DuPont said.

The AOAC Research Institute, a subsidiary of AOAC International in Rockville, Md., validated the BAX System method as equivalent to the reference culture method for detecting Listeria species, but with much faster time to results, the company added.

BAX System assays for Escherichia coli O157:H7, non-O157 STEC, Campylobacter, and other pathogens are already PTM-certified. In addition, AOAC International has awarded Official Method of Analysis status to the system for detecting Salmonella and L. monocytogenes, and DuPont noted that these assays can be run in conjunction with the Listeria species test.
