Assurance GDS for Salmonella. Performance Tested Method 050602

A study was conducted to determine the efficacy of detecting low contamination levels of Salmonella in peanut butter using Assurance GDS for Salmonella (GDS). This study was conducted under the AOAC Research Institute Emergency Response Validation program. A set of samples was each analyzed by the GDS and the U.S. Food and Drug Administration's Bacteriological Analytical Manual reference method. Among the 45 total samples and controls, 26 samples were positive by the GDS and 24 were positive by the reference method. Statistical analyses of these unpaired samples indicated that, for all levels analyzed, the differences between the GDS and reference method results were not statistically different at the 5% level.
