The purpose of this study was to evaluate the bacteriological quality of milk sold in Jimeta metropolis. The bacteriological quality of the milk sold in Jimeta metropolis was assessed by using turbidity test to know the degree of pasteurization of the milk, total bacterial count was undertaking by using pour plate method, most probable number technique was employed for the assessment of coliform bacteria. Bacterial contamination in the untreated milk was ascertained by using methylene blue reductase test. The results of the study revealed that samples for Arewa, Nazir and Admiral’a yoghurt passed the turbidity test because they showed a turbidity value of zero. Out of the nine (9) Kindirmo sample analysed, four (4) satisfied the turbidity test while that of Nono 5 samples satisfied the turbidity test. The plate count for Kindirmo ranges from 3.0x106 CFU/mL to 8.3x107CFU/mL, Nono range from 3.5x106 CFU/mL to 8.9x107CFU/mL and Madara ranges from 3.3x106 CFU/mL to 9.0x106 CFU/mL. For commercial yoghurt, plate count for Arewa yoghurt fall between 3.9x106 CFU/mL to 4.1x106 CFU/mL, Nazir yoghurt plate count ranges from 4.6x106 CFU/mL to 4.7x106 CFU/mL and Admiral ‘a yoghurt ranges from 3.0x109 CFU/mL to 3.3x106 CFU/mL. The results of the study also indicated that the milks have high densities of coliform bacteria in kindirmo, nono and madara compared to the new standard that said a maximum amount of coliform bacteria should not be more than 10 bacteria per milliliter (mL) of milk. However, all the commercial yoghurt analysed satisfy the standard acceptable limit of coliform bacteria. Methylene blue reductase test revealed that all the untreated samples (Madara) decolorized methylene blue in less than 30min.
