Hygiena InSite is a quick and easy presumptive environmental Listeria test that has been designed to monitor presence of Listeria in environmental samples from the food processing environment.
The test contains a liquid media formulated with antibiotics, growth enhancers and colour-changing compounds specific to the growth of Listeria species. A colour change from yellow to light brown/black is considered presumptive positive.
Applicability of Hygiena InSite is limited for selected common Listeria spp (Listeria monocytogenes, L. innocua, L. ivanovii, and L.welshmeri) on selected common surface types.
The test can maximise sample collection by the use of a premoistened sponge swab. The Listeria detection system is an AOAC approved method and can provide presumptive positive results in 30 h, at levels as low as 1-10 CFU/mL. The Listeria kit doesn’t require any measuring or subculturing and the self-contained system is safe to use even if you don’t have a pathogen laboratory. The only equipment needed is a 37°C incubator.
