A Statistical Survey of Dioxin-Like Compounds in U.S. Pork Fat
The purpose of this paper is to report on the results of a joint survey of the United States Department of Agriculture (USDA) and the United States Environmental Protection Agency (EPA) on the rate of occurrence and concentration of chlorinated dibenzo-p-dioxins (CDDs), chlorinated dibenzofurans (CDFs), and coplanar polychlorinated biphenyls (PCBs) in the fat of U.S. pork animals. This survey, conducted in 1997, was the first statistically designed national survey of levels of CDDs/CDFs/PCBs in pork animals in the U.S. It was prompted by EPA's Reassessment of Dioxin-Like Compounds and funded from EPA's Dioxin Exposure Initiative. It is the second joint USDA/EPA effort of its kind, the first being a survey of beef back fat.
