Neogen Corporation has received a matrix extension for its Performance Tested Method Certification from the AOAC Research Institute for its ANSR for Salmonella assay. 


The original AOAC Research Institute approval from June 2012 covered the use of the ANSR system to detect Salmonella in food matrices, including raw ground beef, raw ground turkey, chicken carcass rinse, hot dogs, oat cereal, and sponge or swab samples from stainless steel, plastic, ceramic tile, sealed concrete and rubber environmental surfaces.  In addition to the original claims, the following matrices are now included in the approval: soy flour, cocoa powder, peanut butter, almonds, dry pet food, dried pasteurized egg, black pepper, ice cream, raw shrimp and raw spinach.
