Test for salmonella
20 February 2015
The latest addition to the Hygiena line of rapid micro-organism tests is InSite Salmonella – a rapid and convenient colorimetric Salmonella species test for environmental surfaces.
Its all-in-one test format contains both the pre-enrichment and selective enrichment procedures, maintains security and minimises the risk of cross contamination. It also retains the active culture for any subsequent verification and identification tests.
InSite Salmonella is a self-contained, ready-to-use swab test which contains a specialised liquid medium which changes colour when Salmonella species are present in the sample. A colour change from purple to bright yellow indicates presence, with positive results in as early as 24 hours from sample collection. A short pre-enrichment period of 6 hours gives the optimum and earliest detection of presumptive positive samples in the 24 hour period. Optional overnight or 24 hour pre-enrichment enables detection of such samples in 48 hours. The all-in-one test device eliminates the need for sample preparation materials, saving material and labour costs.
Other environmental Salmonella species test kits are said to require several complicated steps including measurement and mixing of media, sample enrichment, and transfer of enriched sample to the test device. InSite Salmonella’s convenient design eliminates the need for any special preparation, measurement, or enrichment outside the test device, simplifying the assay so any level of user can successfully run the test, thus virtually eliminating the possibility of operator error.
