LANSING — The Lansing-based biotech company Neogen Corp. (Nasdaq: NEOG) said Monday it had developed the quickest and easiest test to definitively detect for contamination with Listeria bacteria.
Ansr for Listeria is the second test available for Neogen’s revolutionary Ansr pathogen detection system, and will provide results after only 20 minutes of reaction time. Other commercially available molecular amplification tests require up to three hours of reaction time. Ansr for Salmonella, which was introduced in April, recently received performance validation from the AOAC Research Institute, and the Listeria test’s approval is pending.
“The well-received and validated Ansr system provides the food industry both the definitive test results they need, and the much easier and quicker methodology they want,” said James Herbert, Neogen chairman and CEO. “This introduction of Ansr for Listeria adds to an extremely productive period for our food safety research and development group. Since March 1, we have launched nine new food safety and quality testing products, including three new mycotoxin tests, two food allergen tests, two indicator organism tests for sterility testing, and now two innovative foodborne pathogen tests.”
Combined with Ansr’s single enrichment step, Neogen’s new pathogen detection method for Listeria can provide definitive results in as little as 16 hours from the time the sample is taken.
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.
Additional tests for the Ansr platform currently are in development and are expected to be launched in the coming months.
Neogen now offers an unmatched industry-specific range of microorganism testing products, experience and expertise — from lateral flow immunoassays to fully automated pathogen and spoilage organism platforms, to a comprehensive catalog of high quality dehydrated culture media, to DNA genotyping technology through its NeoSeek genomic profiling and serotyping service.
Neogen’s Food Safety Division markets dehydrated culture media, and diagnostic test kits to detect foodborne bacteria, natural toxins, food allergens, drug residues, plant diseases and sanitation concerns. Neogen’s Animal Safety Division is a leader in the development of animal genomics along with the manufacturing and distribution of a variety of animal healthcare products, including diagnostics, pharmaceuticals, veterinary instruments, wound care and disinfectants.
