An experiment was conducted to estimate certain organochlorine (OC) pesticides (DDT - Dichloro Diphenyl Trichloroethane, HCH - Hexachloro Cyclo Hexane and Cyclodiene compounds) residues in muscle, liver and kidneys of broiler chicken collected from retail markets of Hyderabad. Among the pesticides residues, the occurrence of DDT was more as compared to HCH and cyclodiene compounds. DDT residues were found in 78.57% of chicken tissue samples. The most prominent metabolite of DDT in chicken liver and kidney tissues was p,p'DDT (para para Dichloro Diphenyl Trichlore ethane), followed p,p'DDE (para para Dichlorodiphenyl Dichlore Ethane) and p,p'DDD (para para Dichloro Diphenyl Dichloroethylene). Muscle samples showed more p,p'DDT followed p,p'DDD and p,p'DDE metabolite. HCH residues were noticed in 71.43% of chicken tissue samples. There was no significant difference in the level and prevalence among various isomers of HCH. Among tissues, kidney samples showed the highest concentration for HCH (0.080 ppm), followed by muscle (0.071 ppm) and liver (0.055 ppm). The concentrations of endosulfan sulfate and heptachlor residues were below detectable level in all the analysed chicken tissues. Further, the levels of all pesticides contaminants were below the maximum residue limit.
