      During the surveillance conducted in 1995, focussing on special slaughter places, 199 samples of urine were analysed for the presence of residues of anabolic steroids and beta-agonists, 93 samples of bovine retina were analysed for the presence of residues of beta-agonists, 50 samples of kidney fat were analysed for the presence of gestagens and 63 samples of kidney were analysed for the presence of tranquillizers. In one sample of urine residues of clenbuterol were detected and in one sample of kidney residues of xylazine were detected. In none of the other samples any residues of the compounds mentioned were detected. We found out that 2 of the 604 samples (originating from 405 animals) were found positive for beta-agonists or tranquillizers.
