Retrospective analysis of case sheets for last three years at the local veterinary dispensary was also carried out Whole blood samples were collected from 20 randomly selected cows for pesticide residue and haematological analysis. Collected samples were processed by various clean up procedures and analysed using Gas Chromatography for HCH and DDT residues. Residues of DDE and DDT were below detection limit (BDL) in all the analysed serum samples. The haematological values of cattle from study area remained within the normal range except differential leucocyte count which exhibited marked lymphocytopenia. In the present study, the level of pesticide residues in the serum samples in the study area was not enough to produce any visible health hazards in cattle.
