TOTAL DIET STUDIES The total diet program is designed to determine the levels of pesticides PCBs, and trace heavy metals in the dietary intake on a geographical and * seasonal basis. Market basket sables, representing the two-week diet of a 15-20 year old male -- which is approximately twice that of the normal diet -- are collected at retail stores, bimonthly, in five regions of the United States. Food items are cooked or prepared for table-ready use by . dieticians and are divided into 12 food class composites, such as dairy products; meat, fish and poultry; and leafy vegetables. Each composite is analyzed for a variety of chemical contaminants, including PCBs, The limit of detectability as applied to total diet composites is approximately 0.05 parts per million PCBs. When abnormally high residues are detected in any composite, follow-up analysis is made of the individual food com modities of the composite to determine which food is contributing the ex cessive residues and to determine whether compliance action is warranted. III. USDA SAMPLING PROGRAMS The Consumer and Marketing Service, USDA, has primary responsibility for sampling and analyzing meats, poultry, and broken egg products for pesticide, environmental (PCB), and other chemical or biological con taminants. The USDA program involves all federally inspected slaughtering plants (about 1,200} and egg breaking establishments (about lLiO). The instructions for sampling request that the agricultural producer of the animal, bird, or eggs, be named so that the State of origin will be known. This facilitates follow-up if a violative sample is found and identifies those samples which originate from the same farm. Inspectors are instructed to collect objective samples from different agricultural producers. The time of sampling and the plant location are determined on a random basis, by computer, for this program. 17. OTHER REGULATORY PROGRAMS In addition to these routine sampling activities, FDA and USDA learn 6f PCB contamination of'foods in other ways. As part of their enforcement responsibilities, they conduct in-plant establishment inspections; con duct special Investigations and surveys to determine the cause and extent of specific PCB problems; and maintain close contact with State officials and industry who also monitor the occurrence of chemical contaminants in food. When required, there is also a selective phase to these sampling programs and investigations* Selective sampling is used to determine the extent of violations when a violative sample is encountered or a report of possible harmful residues is received by the responsible agency. An increased number of samples is taken in the suspected area to determine 109 ACH COO 14 8 f I I I * ADM 000150
