Detection of Salmonella species in a variety of foods by the DuPont Bax system real-time PCR assay for Salmonella: first action 2013.02.

A multilaboratory study was conducted to evaluate the ability of the DuPont BAX System Real-Time PCR Assay for Salmonella to detect the target species in a variety of foods and environmental surfaces. Internal validation studies were performed by DuPont Nutrition & Health on 24 different sample types to demonstrate the reliability of the test method among a wide variety of sample types. Two of these matrixes-pork and turkey frankfurters and pasteurized, not-from-concentrate orange juice without pulp-were each evaluated in 14 independent laboratories as part of the collaborative study to demonstrate repeatability and reproducibility of the internal laboratory results independent of the end user.
