Technical Abstract: This book chapter reviews the literature published over the past five years with regard to the concentrations of historic and newly-listed persistent organic pollutants (POPs) in foods. The chemical classes selected for this review include historic POPs (dioxins, polychlorinated biphenyls, and DDT) and more recent POPs (polybrominated diphenyl ethers, hexabromocyclododecane, and perfluoroctane sulfonic acid). A wide variety of foods from North America, Europe, Asia, and Australia have been analyzed for these POPs. Comparisons of POPs levels between food groups show that fish and animal products generally contain higher concentrations of these contaminants than plant-based foods. Certain regions of the world have higher residue levels of POPs in foods due to local environmental contamination. Examples include fish from waters near industrial and heavily populated areas, backyard or free-range animals and eggs from certain parts of Europe or near BFR recycling sites in China, and marine and animal products from developing countries were the use of DDT may still be occurring. Ultimately, the concentrations of POPs in foods are used to estimate human dietary exposure to these contaminants and, based on the summarize data, show rather uniform dietary intake of these POPs in developed countries.
