AOAC Approves DuPont E. Coli Detection System


The BAX System can now fill several pathogen testing needs.

AOAC International has certified DuPont’s (Wilmington, DE) BAX System as a method for detecting E. coli in beef. Because AOAC is globally recognized for approving microbiological testing methods-it’s the publisher of “Official Methods of Analysis”-certification means that food companies can confidently use the BAX System as their designated method for E. coli testing. But that’s not all.

Because DuPont is also validated by AOAC for other pathogen assays, including Salmonella and Listeria monocytogenes, the company says food companies can use this single platform for all three testing needs. Manufacturers can contact DuPont to learn more about the company’s various pathogen detection systems.

AOAC decided that the BAX System is just as capable of detecting E. coli as the AOAC reference method-only with faster results. The Bax System was created in partnership with the USDA’s Agricultural Research Service.
