Abstract: Broiler Poultry birds intended for human food get exposed to pesticides through feed, water and environment. These residues get accumulated in the muscle, adipose and organ tissues of exposed birds. Therefore the objective of the present investigation was to study the occurrence of organochlorine (OCPS) and organophosphorous (OP) pesticide residues. Each of poultry feed / feed ingredients and meat randomly collected from various poultry farms in and around Hisar city. Multiresidue methods were standardized for simultaneous extraction and detection of residues of OCPS i.e. α-HCH, β-HCH, γ- HCH, δ-HCH, α-endosulfan, β- endosulfan and endosulfan sulfate by GC-ECD technique and residues of OP pesticides i.e. chlorpyrifos, malathion and profenofos by GC-NPD technique. Sample matrices of poultry feed and meat were processed as per the method described by Dutch ministry of Public Health, Welfare and Sports, the Netherlands (AMPRF, 1996). OCP were extracted by soxhlet extraction followed by open column chromatography on aluminium oxide (basic) where, OP were extracted by matrix solid phase dispersion with celite 545 and calcium silicate in acetone – acetonitrile solvent followed by liquid partitioning in n-hexane for cleanup. The results revealed that in poultry feed, the mean levels of total HCH were 618.281Ng/kg while those of HCH in meat were 310.368Ng/kg. The mean levels of endosulfan in poultry feed 135.626Ng/kg, while the levels in meat were 195.057Ng/kg. The mean levels of chlorpyrifos in poultry feed 20.614 Ng/kg, while the levels in meat were 73.473Ng/kg. The mean levels of malathion in poultry feed 6.846 Ng/kg, while the levels in meat were 65.274Ng/kg. The mean levels of profenofos in poultry feed 572.783 Ng/kg. profenofos was not detected in any of the poultry meat samples. Comparison of pesticide concentration in each positive sample of meat with national and international MRLs showed that, lindane among organochlorine and chlorpyrifos among organophosphorous pesticides were responsible for maximum violations. The results of present study demonstrated that the poultry feed is significance source of pesticide residues in poultry meat.
