Neogen Corporation has received a matrix extension to cover foods in the bakery, confectionery and dairy industry for one of its salmonella detection methods.

The ANSR for salmonella assay received the extension from the Performance Tested Method Certification from the AOAC Research Institute.

Soy flour, cocoa powder, peanut butter, almonds, dried pasteurized egg, black pepper, ice cream, raw shrimp and raw spinach are now included in the approval, which had previously covered raw ground beef and turkey, chicken carcass rinse, hot dogs and oat cereal.    

The ANSR system uses an isothermal DNA amplification process to amplify DNA to detectable levels and fluorescent molecular beacon technology for detection of the pathogen target.

Combined with the ANSR’s single enrichment step, the method can provide DNA-definitive results for salmonella in 10 hours from the time the sample is taken.
