Modern dairy processing is a recent phenomenon in Ethiopia for the very reason that therncountry has not been producing enough milk at commercial scale. The establishment of staternowned and private dairy farms in big cities resulted in the realization of the few dairy processingrnplants. In addition to poor transport system and infrastructure of the country, the dairyrnprocessing plants are located far away from farms. This is further aggravated by other facts likernpoor dairy management, poor milking hygiene and lack of good milk cooling and transportrnfacilities and therefore the quality of milk is greatly depreciated by the time it arrives tornprocessing plants.rnThus, the specific objectives of the study are to assess the bacteriological quality of raw milkrnfrom the farm to the processing plant, to determine the bacteriological quality of pasteurizedrnmilk, to identify public health important bacteria from the raw and pasteurized milk and tornidentify the critical control points through the milk collection and processing practices.rnThe study was conducted mainly bacteriological quality tests and bacteriological isolation andrnidentification of sampled milk at different points before pasteurization and at different timernpoints of pasteurized milk and subordinately used questionnaire. Detailed microbiologicalrnanalysis was carried out on selected pathogens of public health importance. For selection of thernsamples, simple random sampling technique was used. The data to be generated from thernquestionnaire and the laboratory tests were summarized and analyzed using appropriaterndescriptive and analytical statistics.rnAs the result of the study showing that 326 bacterial strains were isolated from CCP1 up tornCCP6. There was different species of bacteria in different HACCP levels of milk. In CCP1, therernwere 51 bacteria of different species and in CCP2, CCP3, CCP4, CCP5 and CCP6, was 64, 73,rn80, 20, and 38 respectively. The predominant bacteria species in all (CCP1-CCP5) levels of thernmilk was S. aureus which accounts 14(27.5%), 20(31.3%), 21(28.8%), 17(21.3%), and 6(30.0%)rnrespectively.rnIn line with this the remedial solution for aforementioned identified findings the effective drugsrnwas Ciprofloxacin, Gentamycin, TMP-SMZ, and Ceftriaxone, whereas, Ampicillin and Penicillinrnwere resistant for many of bacteria.rnKey words: milk, bacterial plate count, coliforms, milk hygiene, raw milk, pasteurized milk,rnantibiotic sensitivity
