Today, there is a widely shared belief that the rate of non confirming presumptives (NCP’s) “false positives” in food pathogen diagnostics has increased significantly in recent years. This increase has been most closely associated with PCR and real time PCR testing. It has not yet been possible to answer the question definitively, nevertheless, the belief is real, and the limited data that have been analyzed suggest that non confirming presumptive rates are indeed on the rise.
