DuPont's BAX approved as official Salmonella assay

AOAC International approves BAX System as Official Method of Analysis.

The DuPont™ BAX® System assay for detecting Salmonella—the first method to undergo a new approval process by AOAC International utilizing expert review panels—has been recognized as AOAC Official Method of Analysis (OMA) 2013.02. This molecular-based method uses polymerase chain reaction (PCR) technology and real-time detection to deliver fast and accurate testing results.

Building on previous certification of Performance Tested claims by the AOAC Research Institute, the OMA validation studies demonstrated consistent reliability and repeatability of the BAX System method when testing for Salmonella in a variety of food types such as meat and seafood, beef trim, poultry and eggs, dairy products, produce, cocoa, pepper and infant formula, along with pet food and environmental samples.

“With this latest approval, our entire portfolio of BAX System Salmonella assays is OMA-approved,” said Doris Engesser-Sudlow, global diagnostics leader, DuPont Nutrition & Health. “This means that food companies can choose among our certified methods for the best fit with their food protection needs, confident that each will provide consistently accurate results.”
