The Hygiena™ InSite™ Listeria tests are easy-to-use and self-contained environmental Listeria species test. These tests contain a chromogenic liquid media formulated with antibiotics, growth enhancers, and colour-changing compounds specific to the Listeria species. To use, simply swab the test area and wait. After 24-48 hours of incubation, the test will change in colour which is considered presumptive positive. Expensive lab equipment isn't required and no additional sample handling of the sample is necessary.

• Large 2.5-inch foam swab for maximum sample pickup
• Write-on swab label for easy sample identification
• Presumptive positive results are available for the most common Listeria spp in as little as 30 hours at levels as low as 1-10 CFU/mL. Presumptive positive samples should be confirmed by streaking sample onto commonly used selective Listeria agar plates such as Modified Oxford agar, Palcam agar, or any other recognized confirmatory procedure. Typical Listeria colonies on selective agar plates could then be further analysed by more definitive tests such as microscopy, biochemical tests, etc
• Compared to UVM and BLEB, provides superior/equivalent recovery and faster detection of as low as 10-50 heat injured Listeria monocytogenes/mL within ~24-30 hours of incubation
• Provides higher level of selectivity and sensitivity for heat injured L. monocytogenes under binary competition conditions compared to BLEB and UVM media
• 12 month shelf life at refrigerated temperatures (2-8°C)
