PBBs, PCBs, and dioxins in food animals, their public health implications.

ABSTRACT

Polybrominated biphenyls (PBBs), polychlorinated biphenyls (PCBs), and dioxins are shown to have toxic potential in food animals and humans through laboratory research and investigation of accidental exposures. This article discusses the ball clay incident, as well as other examples of known accidental exposures to PBBs and PCBs. Background information regarding the mechanism of toxicity and effects in animals and humans is also included.
