Variations in microbial load of raw milk and influencing factors form dairy farms to collection centers of Esferayen area
Raw milk is among the highly perishable foods which are subjected to various environmental contaminations following milking. In this study, the factors influencing bacterial load of bulk-milk were investigated. For this purpose, 100 samples were obtained from dairy farms around Esferayen during spri...
