Uptake of different heavy metal residues including cadmium (Cd), chromium (Cr), nickel (Ni), led (Pb), arsenic (As), and mercury (Hg) were determined in goat and cattle milk collected from two areas, each consisted of three sites. Area 1 was selected in the North-East and Area 2 in the North-West of Faisalabad city along the main sewerage drains. Levels of Cd, Cr, Ni, Pb, As and Hg in the milk of goat and cattle were higher than the most reported values in the literature. The levels of heavy metal residues in the milk of cattle from Area 1 were higher than those present in cattle milk from Area 2. However, in case of goat milk the residual values from Area 1 and Area 2 were non-significantly different. It was concluded that the levels of Cd, Cr, Ni, Pb, As and Hg in the milk of goat and cattle were higher than reported values in the literature.
