Odor and Taste Tests of Pork from Animals Sprayed with Benzene Hexachloride¹

Idaho Agricultural Experiment Station

Abstract

Benzene hexachloride has proven to be a very effective insecticide and miticide when used against a number of pests of livestock and poultry.

Hixon and Muma (1947) state that the eggs and meat of poultry may be rendered inedible after birds or poultry houses are treated with this chemical for the control of chicken mites. These workers used a 5-percent concentration of wettable benzene hexachloride containing 5 percent of the gamma isomer and a benzene hexachloride water suspension containing 0.25 percent of the gamma isomer. In contrast, Harwood (1948) and Milby and Lawatsch (1948) reported that when oil emulsions containing 1.25–1.50 percent gamma isomer benzene hexachloride were used there was no effect on the taste of meat and eggs of poultry when applied for mite or louse control. It must be pointed out that these workers applied different solutions and concentrations of this chemical.

Since this station recommends the use of wettable benzene hexachloride for the control of hog lice and mange, tests were conducted to determine whether the meat or lard of hogs would become unpalatable after animals were sprayed with benzene hexachloride.
