This study described the microbial quality of water in a dairy processing plant through coliform assessment. Multiple tube fermentation test and 3Mtm petrifilm E. coli. Coliform plate were used to detect the presence of coliforms and in water used and supplied at the dairy processing plants (water samples were obtained from the faucets in the cooking and processing area, on milk receiving area, dressing room and bottle water). Coliform were recorded in milk receiving area, dressing room and bottled water). Coliform were recorded in milk receiving area and bottled water. The confirmatory test for fecal coliform resulted to be negative for E. coli. All three bacterial isolates exhibited butyrous consistency and smooth colony surface, gram negative, capsulated, coccus with cell arrangement of single to chain. In addition, the siolates are obligate aerole and facultative anaerobe.
