Dieldrin Dilution in Visceral Fat of Field-Contaminated Broilers

Abstract

Broilers aged 4, 5 and 6 weeks were selected from 8 commercial flocks which had been accidentally exposed to dieldrin in feeds. The birds were given a dieldrin-free ration and were reared to 10 weeks of age. Dieldrin residues in visceral fat were determined weekly. Results indicated that dieldrin residues are rapidly diluted in the growing chick with a half-time for dilution of approximately 12 days.
