Anabolic hormones residue in slaughter animals in Poland Examinations of anabolic hormones residues were started in Poland in 1990. Up until now, 1190 animals (cattle, pigs and horses) were tested for residues of stilbenes: diet- hylstilbestrol, hexoestrol, dienestrol; zeranol and trenbo- lone acetate; 400 animals were examined for the presence of non-testosterone, 594 cattle for trenbolone and 199 cattle for medroxyprogesterone acetate. Two hundred and ninety cattle were examined for natural oestradiol 17B and testosterone. Serum natural hormone levels were detected by ELISA, the remaining hormones by HPTLC. No positive results were obtained during the three-year period of examinations. The results show that no anabolic hormones are used for stimulation of slaughtered animals
