NEMIS Technologies Salmonella Risk Test
Salmonella contamination is a major food safety risk in food production environments, but actually detecting salmonella in your facility can be challenging. Enter the N-Light™ Salmonella Risk Test from NEMIS Technologies. Not only does this test detect Salmonella spp., it also detects a small range of closely related bacteria that share genetic and metabolic markers. That means you get a more accurate assessment of the true contamination risk in your facility.
The NEMIS N-Light™ Salmonella Risk Test utilizes our proprietary Aquaspark™ platform which is built on 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™ Salmonella Risk Test produces actionable results in as little as 24 hours. Fast, accurate, easy to use. The future of food systems testing is here.
SALMONELLA SPP. DETECTION – STATUS QUO
Salmonella infections pose a significant health risk, often linked to contaminated food products, making the control of food production crucial. The microbial environment in food production is extensive and intricate, with certain bacterial groups like Enterobacteriaceae and Salmonella spp. often at the center of food safety concerns. Although Salmonella spp. is rarely found in factory settings, appearing in only 2 to 8 out of every 1000 routinely tested samples, total Enterobacteriaceae (TEB) counts can be much higher.
Unfortunately, no clear data links TEB counts to Salmonella spp. in environmental samples, which has been a significant challenge for researchers and industry experts. The EU Scientific Panel highlighted this issue and concluded that it is currently impossible to establish a direct correlation between Enterobacteriaceae and Salmonella spp.
AYOPI Groups are at the Highest Risk
N-Light™ Salmonella Risk – indicator test
N-Light™ Salmonella Risk is not designed to detect only Salmonella spp. Instead, it also targets a small selection of closely related bacteria (such as Citrobacter, Klebsiella and Enterobacter) that share specific metabolic and genetic markers.
Positive N-Light™ Salmonella Risk does not mean finding exclusively Salmonella spp. Instead, it highlights an elevated likelihood of contamination, allowing for timely interventions and corrective actions to ensure food production safety.

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.

N-Light™ Salmonella Risk
NEMIS product REF 00014Product description
N-Light™ Salmonella Risk is a qualitative test method for rapid evaluation of the contamination risk for the foodborne bacterial pathogen Salmonella and a small selection of closely related bacteria that share specific metabolic and genetic markers. The test method is suitable for use in food processing areas and equipment as part of an environmental monitoring program. Final test results are available 24h after sampling.
Storage conditions: 2-8 °C / 36-46 °F, DO NOT FREEZE
Transport conditions: ambient (short duration only)
