Salmonella Test Based on Lateral-Flow System

A lateral flow system Salmonella test kit is now available for the detection of Salmonella in foods. The simple-to-use system is capable of detecting one colony-forming unit (cfu) of Salmonella in a 25 g food sample in just 24 hours. The kit is suitable for use with a wide range of food types, including raw meat and poultry, processed meats, dairy products, eggs, and other fresh produce.

Requiring no capital investment and minimal training, the Dupont lateral flow system Salmonella test kit produced by Oxoid (Basingstoke, UK) is suitable for both large and small laboratories. The specifically designed primary enrichment medium facilitates the recovery of sub-lethally injured and healthy cells in only five hours. Samples are ready to be tested, following a standard secondary enrichment phase, in just 24 hours.

The test strip is placed in a small aliquot of the enrichment broth, the sample migrates along the test strip and, within 10 minutes, the result can be read. A control line demonstrates that the test has performed correctly and the appearance of a second test line indicates a positive result.

The Dupont lateral flow system range includes products for the detection of Listeria and Escherichia coli O157, and complements the Oxoid DuPont Qualicon Bax system for detecting pathogens, including fungi. Oxoid also offers the food industry a comprehensive selection of culture media and manual test kits for the identification of a wide range of food-borne pathogens and food spoilage micro-organisms.
