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 utilises 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 centre 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.

CDC estimates that Salmonella causes approximately 1.2 million illnesses and 450 deaths yearly in the US.

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.

N-Light™ Salmonella Risk

NEMIS product REF 00014

Product 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
