Lindane in Eggs and Chicken Tissues 1

Abstract

Caged laying hens were fed 0.01, 0.10, 1.0 and 10.0 ppm of lindane in their daily ration for 60 days. Up to 10 ppm lindane appears to be well tolerated by hens and does not interfere with egg production, fed intake or utilization and weight maintenance. Lindane was not detected by Schecter-Hornstein chemical analysis at any time in eggs or tissues of birds fed 0.01 ppm; however it was detected in the other levels. Lindane was concentrated in the yolk, none being found in the albumen. Sixty days after termination of feeding lindane, it was found in trace quantities in eggs from the 10-ppm diet, but not in tissues. Skin and visceral fats are the chief storage sites with some appearing in brain tissues and feces at the 10-ppm dosage.
