ABSTRACT

A study was conducted to find out the physico chemical & bacteriological characteristics of Buffalo milk samples in Visakhapatnam district, Andhra Pradesh. The safety of milk is an important attribute for consumers of milk and dairy products. Milk and products derived from milk of dairy cows can harbor a variety of microorganisms and can be important sources of food borne pathogens. The physicochemical assessment of milk is done by performing different tests like PH, colour, water test, clotting test, starch test, urea test, sugar test, salt test, formalin test, boric acid test, vanaspathi test, detergent test and ammonium sulphate test etc.,. the milk samples gave positive to the adulterants. The microbial isolation was done by streak plate method on nutrient agar and on selective media for their identification. The final identification of resulted isolates was done by their biochemical testing mentioned in accordance to the Bergey’s Manual. The resulted bacterial isolates viz. E.coli, and Staphylococcus, are highly pathogenic. Poor quality of milk was recorded as the major risk factor for the alarming diseases.

Keywords: Buffalo Milk, Adulterants, Quality assessment and Pathogenic bacteria.
