Abstract
The presence in foods of chemical contaminants such as heavy metals, pesticides, aflatoxins and polychlorinated biphenyls (PCBs) has been of international concern for decades. Since most of these are associated with intensive industrial and agricultural activity, the minimal existence of such activities in Pacific island countries has led to the conclusion that the consumption of these contaminants in food is unlikely to be a health problem in the Pacific. Because of this little effort has been expended in studying the level of these contarnlnants in Pacific foods. Most of the data are from environmental studies in which some of the analytes are edible. These have mainly been performed at the three major universities in the region, the University of the South Pacific, the University of Guam and the University of Papua New Guinea. Some data are also available from a Japanese study. More recently the United States Environmental Protection Agency has been studying sites potentially contaminated by PCBs in the forrner United States Trust Territories. It should be emphasized that these are scientific studies of the incidence of pollution and not country-driven analyses of the status of these pollutants in the food supply. It is also important to recognize that for the tropical Pacific islands the most important chemical food contaminants are a variety of marine toxins, especially ciguatoxins, that affect health and economies of a significant percentage of Pacific islanders
