The day by day progress of Pakistan has resulted in the development of industries and towns. Contamination is a problem which is related with this progress. Gujranwala District is one of the most developed and industrialized parts of Pakistan selected for this research. In current study seven heavy metals Hg, Pb, Ni, As, Cu, Cd and Ag were detected in the meat samples of cattle (Buffaloes). Out of these, mercury, lead, cadmium and arsenic are the principal lethal metals. The reason for selecting cattle is that they feed on vegetation and are infected by metal pollution as much as the humans. The main reasons for pollution by metals are industries, automobiles, polluted water, pesticides in fields and contaminated soil.
