The prevelance of Listeria spp. and Listeria monocytogenes in ready-to-eat poultry products was examined. Following 16 or 48 h of enrichment and selective plating, presumptive Listeria colonies were identified using polymerase chain reaction and reverse hybridization on line probe assay strips. Overall, Listeria spp. and Listeria monocytogenes were found in 35.5% and 15.5% of the poultry samples, respectively. The incidence of Listeria spp. was much higher in unpackaged (41.7%) than in prepackaged (11.1%) poultry products.
