Test samples were negative for indigenous Salmonella and had an average APC value of 2.7 logCFU/gram. For the 20 samples inoculated, Salmonella was recovered at 80 to 490 CFU/ml by direct plating. All direct unenriched samples were positive by PCR following the iQ-Check Salmonella II standard real-time PCR method and by the USDA-FSIS reference methods after standard enrichment procedure.

Collectively, these data illustrate that the iQ-Check Salmonella II standard real-time PCR method with modification can be used directly and reliably to detect Salmonella at a threshold of 100 CFU/ml (2.00 log CFU/ml) in poultry rinsates without enrichment.
