Intended use

Usage of Compact Dry SL is a simple and safe test procedure for detection of Salmonella in pre-enriched samples of foods or raw materials. The ready-to-use plates consist of a special 50 mm diameter petri dish containing a detection specific nutrient pad.

General Information

Using Compact Dry SL Salmonella can be detected from a specific sample pre-enrichment. The detection can be performed safe and easily according to three different criteria:

1. Color change of the medium from blue-purple to yellow, caused by the alkalization of the medium which is initiated by the Salmonella-specific enzyme lysine-decarboxylase.
2. Appearance of black-green colonies due to degradation of the chromogenic substrate (green) which is contained in the medium combined with the Salmonella specific production of iron hydrogen sulfide (black).
3. The motility of Salmonella which is observed by colonies appearing not only at the origin of inoculation, but also at other areas of the nutrient pad.

The ready-to-use, chromogenic Compact Dry plates are suitable for in-process controls as well as controls of finished products. With the optional additional product Promedia ST-25 swab test (Z0302) Compact Dry plates may also be used for surface sampling and therefore applied for quantitative hygiene monitoring even at surfaces which are difficult to reach.

Benefits:

• Compact Dry SL is therefore an extremely easy-to-use method and also convincing due to the high time saving; a confirmation test is also not necessary.
