ABSTRACT

In present study, the microbiological quality and fat per cent of raw milk in and around Rewa city, MP was evaluated. A total of 100 raw milk samples were collected from local vendors (30), dairy-cum-sweet shops (30) and Veterinary dairy farm (40) and subjected to Standard plate count (SPC), Direct microscopic count (DMC), Direct microscopic somatic cell count (DMSCC), Methylene blue reduction test (MBRT) and fat % analysis. It was found that 28 (70%), 40 (100%) and 34 (85%) dairy farm milk samples were of good quality as per SPC, DMC, MBRT respectively, with 4.28% fat in cow and 8.05% in buffalo milk. The milk samples from Veterinary Dairy farm were found to be of better microbiological quality than vendors and dairy-cum-sweet shop’s milk
indicating good maintenance of sanitary quality while milking/handling/storage, etc., of the raw milk. The majority of milk samples taken from vendors and dairy-cum-sweet shops came under poor or very poor quality suggesting poor milk hygiene when compared to international standards. Fat % of mixed milk collected from vendors and dairy-cum-sweet shops was 3.87% (1-6.5%), which was less than the BIS standard. All the samples from local vendors and dairy-cum-sweet shops tested negative for the DMSCC, however 6 (15%) out of 40 milk samples collected from dairy farm revealed DMSCC count >5 lakh which indicates sub-chronic mastitis. This study yielded information about the quality of raw milk in Rewa and the data is important keeping in mind the significance of sanitary quality of raw milk and its influence on public health.
