Stockfarming: prohibition of substances with hormonal or thyrostatic action and of beta-agonists

This proposal for a directive sought to clarify and consolidate the requirements laid down by the existing directives on substances having a hormonal or thyrostatic action (Directives Nos 81/602/EEC, 88/146/EEC and 88/299/EEC) and to prohibit the use of beta-agonists in stockfarming, for any purpose whatever, except for the therapeutic treatment of horses and pets. �
