Lead is an environmental pollutant which does not only affects human but animals as well. Lead poisoning is the common cause of toxicity in cattle and advancing due to industrialisation. Lead toxicity in cows is an economic loss and also food safety issue in terms of milk, dairy products and meat. Thus, there should be a constant checking on the concentration of lead in cattle. There has, however been little research concerning lead exposure in cattle in India. The objective of this study was

Fodder and water sample were also analysed by X Ray Fluorescence and Atomic Absorption Spectroscopy respectively in order to find out the possible source of lead. Blood lead levels in cows from all the 4 areas(below 4.7 µg/dL) were within the accepted limits. Fodder and water levels of lead ranged below 45 ppm and 0.0053 ppm respectively; and all were within the accepted levels. It is thereby concluded that level of lead in cows in has not reached an alarming level and thus does not pose a threat to animals and man
