Hygiena InSite Salmonella is an all-in-one swab test for screening food processing environments for Salmonella. Swab the surface, pre-enrich in the device, then snap to release the selective medium and incubate at 37 °C. If Salmonella is present, the medium changes from purple to bright yellow. Presumptive positives are visible from 24 hours and negatives are confirmed at 48 hours, with no media prep or transfers.
Hygiena states InSite Salmonella holds AOAC Research Institute Performance Tested Methods℠ certification for stainless steel, plastic, rubber, ceramic and sealed concrete. It's sold in boxes of 50 tests. Hygiena InSite Salmonella is available in Canada from Cambridge Environmental Products with CAD pricing and Canadian purchasing support.
The pre-moistened foam swab, selective medium and pH indicator are in one sealed device. Pre-enrichment and selective enrichment both happen in the same tube, with no transfers.
The medium changes from purple to bright yellow when Salmonella is present. Staff read it by eye against the colour chart on the label.
Hygiena states InSite Salmonella holds AOAC RI Performance Tested Methods℠ certification (#022302) on stainless steel, plastic, rubber, ceramic and sealed concrete.

| Result | What You See | Meaning |
|---|---|---|
