WILMINGTON, Del. – The AOAC Research Institute recently certified the DuPont BAX System Real-Time PCR Assay for L. monocytogenes as a Performance Tested Method. DuPont said the method allows for the detection of Listeria monocytogenes from environmental samples in about 22 hours, one of the fastest time-to-results available for the pathogen. The AOAC Research Institute is a subsidiary of AOAC International in Rockville, Md.

The AOAC certification includes a new combined testing method from environmental samples developed by DuPont Nutrition & Health and FoodChek Systems Inc. of Calgary, Alberta. It combines shorter, simpler sample preparation and faster real-time processing. The company said the test was validated on a variety of sample matrices, including frankfurters, cooked shrimp, spinach, queso fresco and environmental surfaces.

“The additional time savings of approximately four hours associated with using the BAX System real-time PCR assay for L. monocytogenes and Actero Listeria Enrichment Media together provides benefits to end users that can ripple through the manufacturing process, including reduced labor costs and faster product releases,” said Shannon Bullard, Diagnostics global product manager, DuPont Nutrition & Health. “As a market-driven science company, we are proud to work regularly with customers and industry partners like FoodChek to create food safety solutions at both the local and global level.”
