The present study was done to detect the various adulterants with a number of toxic substances in natural milk. In this study we explained the hygienic status, physical properties like color, odour, consistency, P^H sedimente.tc, physicochemical properties like specific gravity and acidity and also detected for presence of various adulterants like starch, cane sugar, pulverized soap, urea, ammonium sulphate, formaldehyde, coloring matter, nitrates in raw milk collected from different areas of local market. A total of 10 samples were collected from different areas localities in Ananthapuramu and determined physical properties and also extent of adulteration. From this study we found various observations like all milk samples were found have similar physical and physicochemical properties with slight variations. No samples were adultered with starch, cane sugar, pulverized soap, ammonium sulphate, formaldehyde, coloring matter, nitrates. All samples were found to be adulterated with urea and skimmed milk.
