Limited study in Bahir Dar City on the microbial quality of mozzarella cheese among small-scale milk processor sectors. Therefore this study aimed to; assess the microbial quality of Mozzarella cheese among small scale milk processing sectors. The study involved a laboratory -based from April 2014 to June 2015. A total of 90 Mozzarella chees e samples were collected from nine small-scale milk processing plants and the mi crobiologically quality of mozzarella cheese was examined. Data were analysed u sing statistical packages for social science (SPSS) 18.0.The mean count of APC, S .aureus count, yeast and mould count, E.coli count and TCC Mozzarella cheese w ere 33.3%, 77.7%, 66.6%, 22.3% and 33.3% of above the limit sets by Europe leg islation respectively. Contamination of E.coli and S.aures was 7.7 % (6/90), and 1 3.3% (12/90) in the mozzarella cheese sample.However, Salmonella was not detec ted. In conclusion, it was shown that the hygienic quality of mozzarella cheese wa s low and did not meet European standards except Salmonella.
