Environmental Assessment

Bioaccumulation Factors and Intake of 2,3,7,8-Polychlorinated Dibenzo-P-Dioxins in the Domestic Chicken

Report Information

One of the most commercially valuable farm animals in the United States is the domestic chicken (Gallus domesticus). Rapidly reared in controlled, intensive environments, the US Department of Agriculture (USDA) estimated the production of these animals exceeded eight billion in the United States during 2002.

During a national survey of dioxin-like compounds in poultry in association with the USEPA/Office of Research and Development's Dioxin Reassessment Program, it was discovered that several chicken samples contained elevated concentrations of PCDDs. It was determined that the source of this contamination in the soybean feed was the ball clay, an anti-caking component of the feed. From the survey calculations were made to determine the bioaccumulation factors, or BAFs, and the intake rates of the PCDDs in the chickens and how they compared to previously reported values.
