Background. The PhageDx™ Salmonella Assay is based on the infection of Salmonella spp. By specific bacteriophages and expression of a luciferase reporter gene. Results. Are generated in as little as 9.5 h for raw ground turkey and 18.5 h for milk-based powdered infant formula (PIF). Objective. An AOAC Performance Tested Methods.SM (PTM) study was conducted to validate the PhageDx Salmonella Assay for the detection of Salmonella in 25g raw ground turkey and 100g PIF test portions. Method. The performance of the PhageDx Salmonella Assay was compared to that of the U.S. Department of Agriculture (USDA), Food Safety and Inspection Service (FSIS) Microbiology Laboratory Guidebook (MLG) 4.10 for raw ground turkey and the U.S. Food and Drug Administration (FDA) Bacteriological Analytical Manual (BAM) Chapter 5 for PIF. Inclusivity/exclusivity, product consistency and stability, and robustness testing were conducted. Results. There was no significant difference between the 25g raw ground turkey and...
