The project is one of a series initiated at the request of the Commission's Agricultural Services (DG VI) to provide RMs in support of Community Policy banning the use of growth promoting compounds in farm animals and the Directive laying down requirements for monitoring of undesirable substances in farm animals and products in Member States (86/469/EEC).
Trenbolone is an exogenous androgenic substance with potent growth promoting ability. It was licensed in some Member States prior to the ban and is still licensed in some third countries including the USA. It is normally administered as an implant but a solution in oil is also manufactured and may be incorporated into illegal 'cocktails'.
The project will involve the preparation of lyophilised urine and muscle from cattle:
- treated with trenbolone
- never treated with trenbolone.
The materials are mainly intended for use by the National control laboratories.
A blank and a trenbolone containing urine RM have been prepared. Final homogeneity studies are completed and the final one year stability study is underway. Certification measurements on these materials are planned in 1992.
