Neogen Corporation has received Performance Tested Method Certification from the AOAC Research Institute for its new ANSR Salmonella assay, which is designed for rapid and definitive detection of Salmonella in food and environmental samples, according to the company.

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 ANSR’s single enrichment step, Neogen’s new pathogen detection method can provide DNA-definitive results for Salmonella in as little as 10 hours from the time the sample is taken. The AOAC approval covers the use of the ANSR system to detect Salmonella in food matrices such as 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.
