Description:Melengestrol acetate (INN, USAN),sometimes abbreviated as MGA, is a steroidal progestin and antineoplastic agent. It is not approved for use in humans, and is instead used as a feed additive to promote growth in cattle, a purpose it is licensed for in the United States and Canada. It is an acetate ester of melengestrol, which in contrast, is not used in either animals or humans.
The use of steroid hormone analogues in animals used for human consumption has been a source ofinternational debate for many years. In the European Union, a total ban of anabolic agents for growth promotion in food animals has been in place since 1988 on the bases of unknown or poorly demonstrated food safety (Stephany 2001). After a review of 17 scientific studies by the Scientific Committee on Veterinary Measures Relating to Public Health, the European Commission concluded that hormonally-treated meat poses a risk to consumers (SCVPH 2002).
Conversely, in Canada and the USA, certain synthetic and natural anabolic steroid hormones are approved for use under controlled regulations (Stephany 2001). Interestingly, after a review of the same 17 studies, Health Canada concluded that residues in beef pose no undue risk to human health, provided the drugs are used and administered appropriately.
