NEMIS Technologies Listeria Test
Listeria is a leading cause of foodborne illness and costly product recalls. Protect your customers and your business with the N-Light™ Listeria Test from NEMIS Technologies. Our simple and effective testing platform allows you to find pathogens sooner and stop outbreaks before they start. Best of all, our tests don’t require complicated training to be properly used. They’re the simple and cost-effective solution to your L. monocytogenes testing problem.
The NEMIS N-Light™ Listeria monocytogenes Rapid Test utilizes our proprietary Aquaspark™ platform which leverages pioneering phage technology to quickly detect even small amounts of live bacteria. Unlike traditional lab tests that take days to get results, the NEMIS N-Light™ Listeria monocytogenes Test produces actionable results in as little as 24 hours. Fast, accurate, easy to use. NEMIS Technologies is revolutionizing food safety.
Listeria monocytogenes — status quo
Listeria infections, often linked to contaminated food products, are primarily caused by the bacterium Listeria monocytogenes. Listeria monocytogenes is a Gram-positive bacterium that is among the leading causes of death from foodborne illness. Although Listeriosis is not the leading cause of foodborne diseases, severe infection has a case-fatality rate of 15% to 30%.

Did You Know That You Invite Listeria into Your Factory Every Day?
The natural home of Listeria monocytogenes is in the fields and, thus, in soil, water, and even harvested vegetables. In that condition, it is termed a saprophyte, as the organism does not cause any harm in this condition. It becomes an issue only when the crops are harvested and brought into the factory. Considering this, most food manufacturers invite Listeria monocytogenes into their factories every day. Every piece of raw material could have Listeria monocytogenes on it.
Nevertheless, raw and fresh produce is consumed daily without people getting sick. This pathogen primarily affects people with a weak immune system and must grow in the food before an infectious dose is reached. The problem is that Listeria monocytogenes can multiply from deficient numbers and reach dangerous levels even at fridge temperatures, so preventing even deficient numbers from contaminating food is crucial.

Consider Your Sampling Needs: N-Light™ MaxiSampler vs N-Light™ swab
By choosing the right tool for each surface type and size, you can meet regulatory guidelines effectively while maximizing sampling efficiency and accuracy.
- Designed for Large Surface Coverage: Excels in sampling larger, flat surfaces such as floors, walls, and countertops. Provides broader detection of potential contamination across sizable zones.
- Guideline Endorsed for Broader Surveillance: Environmental monitoring guidelines often endorse sponges for larger, straightforward areas to capture a comprehensive view of contamination risks.
- Surface Area: With a typical range up to 0.3 m² (like a 30×30 cm area), N-Light™ MaxiSampler maximizes sampling on expansive surfaces, offering robust environmental surveillance.
- Ideal for Hard-to-Reach Areas: Swabs are perfect for narrow or intricate surfaces such as equipment joints, cracks, and small parts that might otherwise be missed.
- Recommended by Guidelines for Small Surface Sampling: Many guidelines, such as those from the FDA and ISO, suggest swabs for sampling limited areas or surfaces with complex geometries.
- Surface Area: Typically covers around 0.1m² (like a 10×10 cm area), making swabs ideal for focused or spot sampling on high-touch or high-risk zones.
