Abstract

A total of 100 milk samples were collected from different farms in Puducherry. Quality analysis was done based on the Methylene Blue dye reduction test and Standard plate count test. As per Methylene blue dye reduction test 30 %, 38 % 28 %, and 4 % of the samples were very good, good, fair, and poor in quality respectively. According to Standard Plate Count 28 %, 36 %, 26 %, and 10 % of the samples were very good, good, fair, and poor in quality respectively. This reflects the hygienic practices followed by the farmer at the farm level including animal health, environmental hygiene, and personnel hygiene. A strong correlation (r = 0.82) was observed between the Methylene blue dye reduction test and Standard Plate Count. Therefore, the Methylene blue dye reduction test can be used effectively, economically, and efficiently, to detect the quality of raw milk compared to costly and tedious microbiological methods.
