Abstract

The purpose of this study was to investigate the presence and prevalance of L. monocytogenes and Salmonella spp. in 100 white cheese samples bought from the neighborhood and village markets in Afyonkarahisar province center. The methods recommended by the American Food and Drug Administration (FDA) were used in the isolation and identification of L. monocytogenes, while International Standard Office (ISO) recommended methods were used to isolate and identify Salmonella spp. Out of the 100 cheese samples taken for analysis, 6% (6/100) were identified as L. monocytogenes and 2% (2/100) were identified as Salmonella spp. The results of the research show that the white cheeses placed on the market for consumption in Afyonkarahisar may be a source of contamination with L. monocytogenes and Salmonella spp. and thus present a potential hazard for public health.
