A total of 125 samples of raw milk were assessed for the overall quality in the three district of Chhattisgarh viz. Durg, Raipur and Rajnandgoan during 2011-2012. All the samples were examined for detection of different adulterants. In present study, adulterants observed in the milk were water 121 (96.8%), formalin 32 (25.6%),urea 64 (51.2%), starch 19 (15.2%), neutralizers 15 (12%), detergent 61 (48.8%), sodium chloride 30 (24%), skim milk powder 4 (3.2%), sugar 25 (20 %), glucose 8 (6.4%), hydrogen peroxide 12 (15%), cellulose 5 (4%), ammonium sulphate 21 (16.8%), protein 36 (28.8%), boric acid 13 (10.4%). Maltose was not observed in any sample. The bacteriological quality of milk was defined by Standard Plate Count (SPC), Methylene Blue Reduction Test (MBRT) and isolation of micro-organisms. On the basis of MBRT analysis, 54 (43.2%), 32 (25.6%), 20 (16%) and 19 (15.2%) were of very poor, poor, fair and good quality respectively. SPC of raw milk of different districts area ranged from 1.56x106- 91.52x106cfu/ml. The microbiological evaluation of these milk sample revealed E.coli in 40% of milk samples.
