Contamination of Meat and Milk by Chlorinated Hydrocarbon Insecticides Used for Livestock Pest Control1

Abstract

Three years'' studies on the effects of sprays and dips of DDT, TDE, methoxychlor, chlordane, toxaphene, lindane, and technical benzene hexachloride are reviewed. All the insecticides, when applied to livestock as sprays or dips, were absorbed and stored in the fat. Data are given on the circumstances, extent, and duration of such storage. The insecticides for which sufficiently sensitive analytical methods have been developed were also found in the milk of treated cows.
