During Fiscal Years 1989-1994, the U.S. Food and Drug Administration (FDA) collected and analyzed 545 domestic surveillance samples of mixed feed rations (172 for cattle, 125 for poultry, 83 for swine, 61 for pets, 56 for fish, and 48 miscellaneous). All samples were analyzed by gas-liquid chromatography for organohalogen and organophosphorus pesticides. Of the 545 samples, 88 (16.1%) did not contain detectable pesticide residues. In the 457 samples with detectable pesticide levels, 804 residues (654 quantitable and 150 trace) were found. None of these 804 residues exceeded regulatory guidance. Malathion, chlorpyrifos-methyl, diazinon, chlorpyrifos, and pirimiphos-methyl were the most commonly detected pesticides. These 5 organophosphorus pesticides accounted for 93.4% of all pesticide residues detected (malathion, 52.9%; chlorpyrifos-methyl, 25.2%; diazinon, 7.7%; chlorpyrifos, 4.9%; and pirimiphos-methyl, 2.7%). Their median values in samples containing quantitable levels ranged from 0.014 to 0.098 ppm. The most commonly detected organohalogen compounds were methoxychlor, DDE, PCB, dieldrin, pentachloronitrobenzene, and lindane. These 6 compounds combined accounted for only 4.1% of all residues detected. FDA is continuing its pesticide surveillance of feeds to help ensure animal safety and prevent violative residues in food derived from animals.
