Abstract

The presence of synthetic hormones including dienoestrol diethylstilboestrol hexoestrol and oestradiol is not permitted in foods to be sold in Hong Kond necessitating an effective surveillance programme. In the past several testing methods for the detection of synthetic hormone residues were tried out in the Government Laboratory. The method currently adopted comprises high performance liquid chromatography for the determination of synthetic hormone residues and the use of several techniques including gas chromatography-mass spectrometry Fourier transform infra-red spectrophotometry and high performance thin layer chromatography for further confirmation. So far hexoestrol has been the most frequently detected synthetic hormone in our surveillance programme. Recently discrepancies in laboratory findings on imported chicken wings brought about collaborative study involving a foreign regulatory body and the Government laboratory in Hong Kong. It was later found that the initial discrepancies in findings between the two laboratories were due to gross sample inhomogeneity in the shipment of chicken wings
