Americas: DuPont’s system receives AOAC-RI certification


The AOAC Research Institute (AOAC-RI) has approved a method extension of Performance Tested Method #030502 to include the latest DuPont BAX System X5 PCR Assay for Genus Listeria.

This approval validates the assay as a reliable method for detecting Listeria species in frankfurters, smoked salmon, spinach and cheese and from environmental surfaces.

“Listeria testing is critical for the food industry – particularly for dairy products, fresh produce and ready-to-eat meats – as an indicator that harmful L. monocytogenes may be present,” said Troy Ayers, Americas sales leader for diagnostics, DuPont Nutrition & Health.

The system provides automated polymerase chain reaction (PCR)-based DNA amplification and automatic pathogen detection for up to 32 samples at a time.

It was introduced to the food industry in July 2015 and is designed to offer the same fast, accurate and easy-to-use pathogen detection solution that customers expect from the BAX System method, but in a smaller lightweight construction to provide greater testing flexibility.

BAX System X5 PCR assays were previously validated by AOAC-RI for detecting Salmonella and L. monocytogenes in food and environmental samples.
