title: Comparison of TaqMan Salmonella amplification/detection kit with standard culture procedure for detection of Salmonella in meat samples.
abstract: We evaluated the TaqMan PCR Salmonella amplification/detection kit (PE Applied Biosystems) for rapid detection of Salmonella from a variety of meat samples. This system uses the 5' nuclease activity of Taq DNA polymerase, which digests an internal fluorogenic probe to monitor the amplification of the target gene. The detection sensitivity of the kit, using 2 kinds of DNA extraction protocols, was compared with that obtained with 4 protocols of official culture methods. A total of 98 meat samples (16 raw beef, 31 pork and 51 chicken) were tested. The results of the TaqMan PCR method and the combined results of the 4 cultural protocols showed excellent agreement. However, no single culture protocol showed optimal recovery of Salmonella comparable to the PCR method. These results suggest that the TaqMan PCR method is a reliable and rapid method useful for detecting Salmonella in meat products.
