Neogen Corporation has developed the quickest and easiest test to definitively detect Listeria monocytogenes. This is the third test available for Neogen’s innovative ANSR pathogen detection system, and will provide results after only 10 minutes of reaction time following enrichment. The new test joins Neogen’s line of ANSR products, which also includes AOAC Research Institute-validated ANSR for Listeria and ANSR for Salmonella.

"The well-received and validated ANSR system provides the food industry definitive test results, and much easier and quicker methodology," said Ed Bradley, Neogen’s vice president of Food Safety. "This introduction of ANSR for Listeria monocytogenes will allow the testing for Listeria monocytogenes and Listeria species from a single enriched sample.

Combined with ANSR’s single-step enrichment, Neogen’s new pathogen detection method for L. monocytogenes can provide definitive results in as little as 25 hours from the time the sample is taken. The new test also utilizes Neogen’s LESS Plus Medium, which can be autoclaved — allowing for larger batches of media to be prepared prior to use.

Neogen’s ANSR is an isothermal amplification reaction test method that exponentially amplifies the DNA of any bacteria present in samples to detectable levels in only minutes. The ANSR system was designed to combine molecular-level accuracy with a scalable low-cost instrument and a methodology that can be easily incorporated into any testing laboratory’s existing workflow. The system’s small benchtop footprint and extremely simple procedure make it an easy fit in any laboratory setting.
