“…In the feeding studies reported here, a 7-day treatment period was used to simulate the time a commercial poultry producer might be using one bulk delivery of feed. The dusting studies attempted to simulate the unintentional contamination of "safe" insecticides such as Co-Ral, malathion, and Sevin with chlorinated hydrocarbon insecticides shown to occur in the manufacture, distribution, and use of these insecticides (McCaskill, 1968). EXPERIMENTAL Analytical Method.…”

Working levels," used by the Florida Department of Agriculture prior to issuance of FDA action level guidelines, were used as criteria. For whole eggs these levels were 0.05 p.p.m. for DDT, BHC, lindane, and methoxychlor and 0.01 for aldrin, dieldrin, and chlordane. The dusting of laying hens with "safe" insecticides contaminated with as little as 200 p.p.m. of DDT caused residues in the egg to exceed the working level. Dusts with up to 300 p.p.m. of BHC did not exceed 0.05 p.p.m. in the eggs. A dust contaminated with With the passage in 1954 of the Miller Amendment to the Food, Drug, and Cosmetic Act of 1938, pesticide residues became a serious problem to producers of poultry and food and feedstuff's. No tolerances have been established for chlorinated hydrocarbon residues in poultry, meat, and eggs, and, in the absence of such established tolerances, a zero level has automatically been the tolerance level. Some enforcement agencies, however, have been using so-called "working zeros" or "working levels," above which the product would be considered unacceptable and legal action taken. Action level guides were issued (Food and Drug Administration, 1967) for certain pesticides of concern to the poultry industry. These levels were considerably higher than those previously used by the Florida Department of Agriculture (Table I). For the studies reported in this paper the working levels of the Florida Department of Agriculture were used as levels of unacceptability. The Food and Drug Administration action level guides are not to be considered as predictions of the negligible residue tolerances that may be established at a later date.Early studies of pesticides and poultry dealt primarily with toxicity of the pesticide to the birds themselves. In recent years there have been a number of published reports on pesticide residues in both poultry and eggs. In many of these studies levels fed resulted in residues much above acceptable levels. One of the most complete and practical studies to date on the feeding of chlorinated hydrocarbon insecticides to laying hens was conducted by Cummings et al. (1966). Low levels (0.05, 0.15, and 0.45 p.p.m.) of lindane, DDT, heptachlor epoxide, dieldrin, and endrin were fed to hens and the accumulation and depletion of the pesticides in eggs determined.
