A Study to Evaluate the Levels of Dioxin-Like Compounds in Dairy Feeds in the U.S.
The Environmental Protection Agency (EPA), in cooperation with USDA and the US Food and Drug Administration (FDA), has undertaken a program to study the presence of dioxin-like compounds in animal feeds. Two phases of this program have been completed, and this paper reports on the third phase. The first phase was a study on the mass balance of dioxins in lactating cows. The objective of that study was to quantify the role feeds play in total dairy cow exposures. The second phase of the program involved the collections and measurement of dioxins in minor feed components. Dioxins in specific targeted animal feed components of interest, including animal and plant byproducts were measured. The third phase involved sampling of total mixed dairy feeds and feed components from dairy facilities around the United States, and measuring for dioxin-like compounds.
