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.
Zeranol is an exogenous oestrogenic 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 it may be incorporated into illegal 'cocktails'.
It is monitored in urine, faeces (on-site inspection), bile and in muscle.
The project will involve the preparation of samples of lyophilised urine, liver and muscle from cattle:
- treated with zeranol
- never treated with zeranol
Preparation of materials and initial stability studies will be completed in 1992.
