Distribution and fate of various contaminants (PCDD/Fs, DL-PCBs, HBCDs, TBBPA) in cow meat and their organs

Various contaminants have persisted in environmental matrices and affected to ecosystem through the food chain from their sources to human. Especially, the concerned contaminants, emitted by human activity and industrial use, have been studied for their fate and estimated dietary intakes such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenyls (DL-PCBs) and hexabromocyclododecanes (HBCDs), tetrabromobisphenol A (TBBPA). In this study, we investigated various parts of beef and their internal organs from singular cow, and discussed how these contaminants spread to those parts. In the case of meat, muscle parts are more generally monitored as the main edible part rather than internal organs. But various parts including rarely consumed internal organ parts in other countries were also monitored in this study. In the general view of food sampling, meat packing processes are legally managed and prohibited a direct taking-out from the slaughterhouse. Thus, the permission from Korea government should be required for sampling in advance; as a result, we secured a strong point from selection of sample unlike general monitoring studies.
