Neogen® offers an innovative molecular detection test for Listeria monocytogenes for in food and environmental samples, as well as dehydrated culture media for traditional detection methods.

Listeria spp. Can be found throughout the environment, and therefore, there is a potential for Listeria contamination in a wide variety of foods. Meat, eggs, chicken, seafood, dairy products and vegetables have all been identified as sources of Listeria outbreaks. The genus Listeria is comprised of six species, with Listeria monocytogenes the only one of the six that causes human illness.

Neogen’s ANSR® test for Listeria monocytogenes utilizes patent-pending, unique amplification reaction technology for in vitro DNA amplification. ANSR’s amplification methodology exponentially amplifies the DNA of any target bacteria present in enriched food or environmental samples to detectable levels in only minutes.

Neogen’s GeneQuence® for Listeria monocytogenes test kits are versatile, as they can be run manually, semi-automated, or fully automated. The DSX Platform is a fully automated four-plate processing system capable of simultaneously performing extremely specific assays for E. coli O157:H7, Salmonella, Listeria, and L. monocytogenes.

ISO-GRID® durable and NEO-GRID® disposable membrane filter test systems are used on food, beverage and water samples for the detection, confirmation, and enumeration of microorganisms.
