Abstract

This study was done with the aim of identification of critical contaminating points of raw milk from udder to dairy factory in traditional dairy farms. Three collection centers and 9 farms were selected in FARS PROVINCE. 392 raw milk samples were collected from udders, milking machine, milk in cans in collection center, bulk tank of collection center and milk transport vehicle at receiving platform in dairy plant. The samples were examined for total microbial, coliform and E. coli count and also acidity and pH. Data were analyzed using GLM procedure in SAS. Geometrical means of total microbial count at various stages were 1.5x105 , 7.5x105 , 9.4x105 , 8.3x106 , 6.2x106 CFU ml-1, respectively. Total microbial count, coliform count and acidity were significantly increased in milking machine stage and bulk tank of collection center stage in comparison with pervious stages (p<0.0001). E. coli count was significantly higher (p<0.0001) and pH was significantly lower (p<0.0001) in bulk tank of collection center stage in comparison with pervious stages. All of the measured items were significantly higher in bulk tank of collection center stage than udders stage in different seasons. Results suggest milking machine and bulk tank of collection center stages are critical contaminating points of raw milk during production in traditional dairy farms and imply localization executive, educational and investigative activity on these critical points.
