1. Intended use

Usage of Compact Dry LS Listeria species is a simple and safe test procedure for quantification of Listeria contaminations in foods or raw materials – as well as pharmaceutical raw materials. The ready-to-use plates consist of a special 50 mm diameter petri dish containing a detection-specific nutrient pad.

2. General Information

- Listeria can be found in almost all areas of life. It is possible to assess the risk of contamination via quantitative detection to ensure that, if necessary, preventive measures can be taken. Listeria monocytogenes, in particular, is considered a major cause of food poisoning, possibly resulting in the development of sepsis, meningitis, and encephalitis.

- Compact Dry LS Listeria spp. contains a standard nutrient medium for the detection of Listeria spp. Due to the integrated chromogenic substances in the medium, Listeria grows as blue colonies with a diameter of between one and two millimeters. It is common knowledge that Listeria ivanovii grows very slowly and L. seeligeri is inhibited.

- 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 that are difficult to reach.

3. Benefits

- CompactDry LS Listeria species is a ready-to-use, dehydrated chromogenic growth medium for enumeration and detection of Listeria species in food and drinks.

- In addition, CompactDry LS Listeria species is used for Listeria detection to monitor surfaces and production areas in combination with CompactDry Swabs.
