Salmonella bacteria are the most commonly reported cause of foodborne illnesses. Hygiena International’s recently developed InSite Salmonella micro-organism colorimetric test is rapid, convenient and extremely accurate. It combines both swab, pre-enrichment and selective enrichment in a single self-contained swab device for testing environmental surfaces, giving results in 24 hours.

Hygiena InSite is a cost-effective Salmonella screening test for food contact surfaces, processing equipment and general environmental samples that combines the principal steps of pre-enrichment and selective enrichment in an all-in-one swab device. The test consists of a large sponge swab pre-wetted with a neutralising agent – to counter the effects of residual sanitisers – and a pre-enrichment broth to enable the detection of low numbers of Salmonella.

The bulb contains the AOAC enrichment Salmonella Indicator Broth PDX-SIB. After activation and incubation, a colour change of the selective enrichment broth from purple to yellow is considered as a ‘presumptive positive’ result.

A brief pre-enrichment period of just six hours enables the detection of presumptive positive samples within a 24-hour period. Alternatively, optional overnight or 24-hour pre-enrichment permits the detection of such samples in 48 hours. The test requires fewer materials, fewer steps and less manipulation by users. Furthermore, its all-in-one format maintains security by confining hazardous pathogens.

Hygiena InSite is quick, straightforward and reliable, while further benefits include reduced risk of cross-contamination and the retention of active culture for any subsequent verification and identification tests.
