- L. monocytogenes Test
One-step Listeria monocytogenes detection test for actionable results in 24h
Why develop a new rapid test for Listeria? There is increasing awareness across the food industry of the importance of environmental monitoring and assessment for Listeria. After all, relying solely on end-product testing means accepting a steadily rising risk of end-product contamination.
Our cost-effective rapid test enables extensive and frequent testing of pathogen environmental monitoring, which greatly increases the likelihood of detecting pathogen hot spots early on. Consequently, the spread of Listeria monocytogenes throughout the factory environment can be prevented.
For most diagnostic companies, environmental monitoring is just a small part of their business. On the contrary, for NEMIS, it is at the heart of what we do.
Increase your testing volume, decrease your risk and maintain your budget. Find out more about designing an effective environmental monitoring program for Listeria monocytogenes and other pathogens here.

N-LIGHTTM LISTERIA RAPID TEST AS YOUR DETECTION TOOL OF CHOICE
Various foods, from cheeses to delicatessen meats and vegetables, can be responsible for Listeriosis outbreaks. Because Listeria monocytogenes is extremely widespread in soil, water, and livestock environments, it is simply a matter of time before the pathogen enters a specific factory.
Once in a production environment, there is a real danger of the Listeria monocytogenes establishing itself as a permanent resident due to its tolerance to high salt concentrations and temperatures as low as 4°C.
RESULTS YOU CAN TRUST
N-LightTM Listeria monocytogenes consistently demonstrates superior sensitivity and specificity compared to the chromogenic competition in the detection of the pathogen.
