Toxicity of Chlordane to Turkey Poults

Chlordane was used to control red ants that had entered a room housing some poults which were on critical coccidiosis experiments at the Ohio Agricultural Experiment Station. Since the ants were highly undesirable, the room and cages were sprayed with this insecticide which is generally recognized as being quite specific for ant control. It was realized that the insecticide might be toxic. Even so, the poults were allowed to remain in the cages to obtain further information on the degree of toxicity. It was necessary that a thorough job of eradicating the ants be accomplished, even at the expense of losing a few poults. A mixture of equal parts of two percent chlordane and 0.4 percent lindane was used to control flies as well as ants. Lehman (1950) reported that chlordane is four times as toxic as DDT. He claims that the chlorine content of the insecticide seems to have …
