THE EFFECTS OF PROCESSING AND STORAGE OF DAIRY PRODUCTS ON CHLORINATED INSECTICIDE RESIDUE1, 2

Abstract

Summary The effects of processing and storage of butter, ice cream, Swiss-type cheese, condensed milk, and dry whole milk powder from milk containing DDT, lindane, and DDT and lindane in combination were studied. The only change in structure occurred to DDT and lindane during drying of the milk into powder. Lindane suppressed the amount of DDT residue in milk when both insecticides were fed together. In general, the finished products other than dry whole milk contained the same amount of insecticide as the raw milk when expressed on a fat basis.
