Authentication of meat and commercial meat products from common pigeon (Columba livia) woodpigeon (Columba palumbus) and stock pigeon (Columba oenas) using a TaqMan real-time PCR assay

A species-specific real-time polymerase chain reaction (PCR) assay using TaqMan^® probes has been developed for the identification of meat and meat products from common pigeon (Columba livia), woodpigeon (Columba palumbus) and stock pigeon (Columba oenas). The method combines the use of species-specific primers and TaqMan^® probes that amplify small fragments (amplicons < 200 base pairs) of the mitochondrial 12S rRNA gene, and an endogenous control primer pair that amplifies a 141 bp fragment of the nuclear 18S rRNA gene from eukaryotic DNA. Analysis of experimental raw and heat-treated binary mixtures as well as of commercial meat products from the target species, demonstrated the suitability of the assay for the detection of the target DNAs. The PCR assay reported in this work could be useful in inspection programs to verify the correct labelling of raw and heat-treated pigeon meat products.
