Factors in the accumulation of dieldrin in broiler organs: quantity ingested, sex and weight of animal

Opinion of the Scientific Panel on contaminants in the food chain [CONTAM] related to aldrin and dieldrin as undesirable substance in animal feed

“…In hens, dietary exposed to dieldrin (0.75 mg/kg of feed) (Gannon et al, 1959b), residues in fat after 12 weeks of exposure were above 35 mg/kg. In addition to fat, dieldrin tended to accumulate in liver and to a lesser extent in kidney, whereas the lowest concentrations were found in muscle (Gallego-Iniesta et al, 1986. Shubat and Curtis (1986) investigated the tissue distribution of a single oral dose of 14 C-dieldrin (0.087 µg/g fish) in rainbow trout.…”
