MetadataShow full item record
The aim of this study was to investigate the presence of Listeria species in the milk and silage samples obtained from fifteen different farms in Burdur. A total of 250 samples (silage and cow's milk obtained from animals fed and not fed with silage) were analyzed. L. monocytogenes was isolated in 6 (2.4%) out of the 250 samples. Five (6.66%) of the 75 silage samples and 1 (1.17%) of the 85 milk samples obtained from cows fed with silage were contaminated with L. monocytogenes, whereas no Listeria spp. were isolated from the 90 milk samples from cows not fed with silage. The isolation of L. monocytogenes from milk and silage samples in Burdur indicates that these products could create a serious risk to the public health.
