ABSTRACT

From June 2001 to August 2002, 210 samples of fresh meat (including 100 samples of pork and 110 samples of chicken) were tested for steroid hormone residues (testosterol, oestrogen, and diethyl stybestrol). Results showed that 8.5% of samples contained hormone residues, in which, 72% contained oestrogen, 28% contained testosterol, and 11 samples (5.2%) contained diethyl stybestrol - these hormone were forbidden for use in cattle and poultry breeding
