Nortestosterone is commonly found in illegal cocktails used for treating cattle. Reference materials (RM) have been prepared form urine of cattle treated with nortestosterone or untreated (blank). Stability studies of urine RMs demonstrated instability at +4 C and above. A further study has been carried out to investigate the use of additives to stabilize the urine RMS.
The project is one of a series initiated at the request of the Commission's Agricultural Services (DG VI) to provide RMs for support of Community Policy banning the growth promoting compounds in farm animals. Relevant Directives/regulations include : 81/602/EEC and 85/358/EEC banning the use of hormonally active compounds in farm animals, 86/469/EEC laying down requirements for monitoring of undesirable substances in farm animals and products in Member States (sampling frequency).
Nor-testosterone, an androgenic substance with potent growth promoting ability and which does not occur naturally in farm animals, except the male horse. It is commonly found in "illegal" cocktails used for treating cattle.
The project will consist in preparing samples of muscle and of urine from cattle :
- treated with nor-testosterone
- never treated with nor-testosterone (blank).
The reference materials are mainly intended for use by National control laboratories.
