Incidence of Listeria monocytogenes in retail chicken meat and establishing relationship with some bacteria by logistic regression

The objective of this study was to determine the contamination of retail poultry meat in Erzurum (Turkey) by Listeria monocytogenes and to evaluate its relationship with indicator bacteria using logistic regression. The incidence of L. monocytogenes was 32.76%, found in 38 of 116 samples. The application of logistic regression showed Enterobacteriaceae, Pseudomonas spp. and Brochothrix thermosphacta populations have positive, and yeast and mold population have negative relationship with L. monocytogenes presence. The results of this study demonstrate that there is a serious risk in raw poultry meat for consumer health in Erzurum, because of the high incidence of L. monocytogenes in the samples of the present study. Hygienic conditions described in HACCP program should still be enforced in order to minimize L. monocytogenes in poultry meat during the processing.
