Abstract:
The present study was undertaken to assess the incidence of microbial load of pasteurized, Ultra High Temperature treated and badam milk sold in and around Greater Hyderabad Municipal Corporation in Telangana State. A total of 150 samples (50 each of pasteurized, Ultra High Temperature treated and badam milk) from 5 commonly available brands were collected and analyzed for total viable count, Escherichia coli, coliforms, Staphylococcus aureus and Salmonella spp. In pasteurized milk, the mean total viable counts were 3.5x104, 1.81x104, 2.5x103, 2.85x103 and 4x104 in B1, B2, B3, B4 and B5 brands respectively. The mean coliforms and Escherichia coli counts were 3 and 0.2/gm in B5 brand, whereas all other four brands were negative. The Salmonella and Staphylococcus aureus are negative in all 5 brands. In Ultra High Temperature treated milk the total viable counts were nil upto 30th day at both 4 0C and 25 0C storage temperatures and on 45th day the counts were 2.5x101 and 3x102 at 4 0C and 25 0C of storage respectively. The coliforms count was nil at 4 0C and 25 0C upto 30th day and on 45th day the counts were 3 and 5 at 4 0C and 25 0C respectively. The Escherichia coli counts were nil at both temperatures upto 30th day and on 45th day the counts were 2 and 3 at 4 0C and 25 0C respectively. The Salmonella and Staphylococcus aureus were negative during entire storage period. In badam milk the total viable countswere nil upto 30th day at 4 0C and 25 0C and on 45th day the counts were 4x101 and 3x102 at 4 0C and 25 0C respectively. The coliforms countswere nil at 4 0C and 25 0C upto 30th day and on 45th day the counts were 4 and 6 at 4 0C and 25 0C respectively. The Escherichia coli countswere nil at 4 0C and 25 0C upto 30th day and on 45th day the countswere as 2 and 3 at 4 0C and 25 0C respectively. The Salmonella and Staphylococcus aureuswere negative during entire storage period 45th day.
