Health Canada has included US-based biotechnology company Hygiena’s BAX system real-time PCR assay as a validated method to screen and detect Listeria species.
The methodology of the assay is now available in Health Canada’s official methods guide called Compendium of Analytical Methods, which is used by the Health Products and Food division.
The system can be used to perform a single-stage, 20-24-hour enrichment and real-time PCR processing to detect the presence of Listeria on various environmental surfaces.
Unlike the standard cell cultures, BAX system yields results within 24 hours.
Hygiena chief scientific officer Martin Easter said: “This validates the BAX system method for reference laboratories to help maintain the safety and quality of our food supply, and provides highly accurate results to help release products faster and save inventory costs.”
In 2014, the Association of Official Analytical Chemists (AOAC) Research Institute’s Performance Tested Methods programme certified the performance of the BAX system real-time Genus Listeria.
The Compendium also lists various BAX system assays that can detect a variety of organisms such as Enterobacter sakazakii, L Genus, L monocytogenes, E coli O157:H7, and Salmonella.
The automated genetics-based BAX system is designed to screen and detect target bacteria in raw ingredients, finished food products and environmental samples.
Hygiena expanded its food safety diagnostics portfolio with the acquisition of DuPont Diagnostics in March. The BAX system, RiboPrinter system, Lateral Flow system, StatMedia and Dehydrated Culture Media were all included in the portfolio.
