The study was conducted in the year 2022-2023 in Hyderabad. The milk samples of total 50 was collected and categorized as raw and pasteurized milk samples. Among 50 samples raw milk samples are 35 no. and pasteurized milk 15 no. The samples were tested for MBRT following the procedure of APHA, 1978. The samples were tested for the change of colour with 0.1 % methylene blue dye color in 20 minutes to 5 hours at 36 0 C ± 10C by using water bath. The discoloration was observed in 26 (52%) samples with within 5 hours which indicates high microbial contamination and low quality samples. Whereas 24 (48%) samples retained the color even after 5 hours which indicates good quality of samples. 90% of the pasteurized samples and 70% of raw samples are good in quality.

Key words: Milk, MBRT, Pasteurized, Hyderabad and microbial contamination.
