END-USERS › Salmonella detection in milk

EC regulation for Salmonella requires that there is no bacteria present in 25 mg of the food sample. For this reasons, all standard practices, i.e. culturing and microscope counting or state-of-the art molecular diagnostic methodologies (PCR), require pre-enrichment of the food sample (normally 18-24 hrs) in order to reach a sufficiently high bacteria sample to be reliably detected by the applied methodology. LOVE-FOOD innovation is to reduce significantly pre-enrichment time (~4 hrs) thanks to the use of microchannels for efficient capturing of as little as 50-100 cells and subsequent handling of ng of purified DNA. Moreover, the high sensitivity of acoustic detection, which goes down to DNA coming from as little as 5 bacteria, ensures the reliable detection of Salmonella.
