Abstract

Chlorinated hydrocarbon insecticide and chlorpyriphos residues were monitored in various parts of chicken sampled from Coimbatore, Tamil Nadu at the Department of Entomology, Tamil Nadu Agricultural University, Coimbatore. The results revealed that the liver and gizzard samples of chicken were contaminated with all the four HCH isomers. While, fat and flesh samples were contaminated only with a and y isomers of HCH. Heart was the least contaminated part with the residues of only y isomers of HCH and chlorpyriphos. The maximum level of HCH, endosulfan, DDT and chlorpyriphos residues in chicken was 0.227, 0.375, 0.119 and 0.469 μg/g respectively. Gizzard followed by liver was the most contaminated parts as against the heart, which was the least contaminated organ. None of the parts of chicken were contaminated with any of the organochlorine and chlorpyriphos residues above the maximum tolerance limit
