ABSTRACT
Milk is an essential food for human beings and it also acts as a good medium for microorganism's growth. A total of 60 cows' raw milk samples were processed for bacteriological and biochemical analyses, collected from different locations of District Peshawar, Pakistan. Bacteriological analysis was performed for the detection of Coliforms including E.coli, and E.aerogenes. Tests were also performed for detection of Salmonella. Analysis was done on specific media, while for confirmation of bacteria, various biochemical tests were performed. Coliforms were detected in 35% milk samples in which E.coli were detected in 31.67% milk samples while E.aerogenes were detected in 26.67% milk samples. Salmonella was detected in lowest percentage with 6.67%. Biochemical tests were also performed for detection of various adulterants in theses milk samples using MAT (Milk adulteration Test) kit prepared by WTO Labs, UVAS, Lahore, Pakistan. Tests were performed for detection of urea, detergents, salt, starch, sugar, formalin, boric acid, carbonates, hydrogen peroxide and ammonium sulphate. Formalin was detected in highest percentage with 28.33% followed by starch which was recorded in 26.67% milk samples. The other adulterants like carbonates, sugar, salt and ammonium sulphate and boric acid were detected in 21.67%, 18.33%, 16.67% and 11.67% milk samples respectively. None of the milk sample was found positive for urea, hydrogen peroxide and detergents adulteration. It was concluded from the present study that raw cows' milk is mostly contaminated with bacteria and adulterated with different chemicals which may lead to various health hazards.
