This paper presents the results of studies on the levels of organochlorine pesticides (HCH, DDT, DDE, DDD) and polychlorinated biphenyls (PCBs) in the adipose tissue of geese and turkeys in Varmia and Mazuria. The birds were slaughtered in summer 1996. Average levels of ∑DDT residues in the adipose fat of geese was 89.3 µg/kg and of γ-HCH 0.8 µg/kg, while turkey fat contained 13.5 µg /kg and 2.5 µg /kg, respectively. Average residues of PCBs in goose adipose fat amounted to 5.1 µg/kg, and in turkey fat to 4.9 µg/kg. DDT dominated in both, goose and turkey fat, DDE percentage was twice higher in turkey fat than in geese, while DDD levels were a little lower in turkeys than in geese. These results add to the inventory of residues of these xenobiotics in the tissues of domestic birds bred in Northeastern Poland.
