Within the framework of the European Commission's Falcone programme, the Belgian Interdepartmental Residues Cell set up the BUFALAW- project for the study of the legislation and the organisation concerning the fight against the illegal use of growth promoters in stock farming in the Member States and candidate countries of the European Union. This book contains the results of the comparative study that was established by Ghent University, which provides a comparative analysis of the arrangements across 19 European States concerning the fight against the illegal use of growth promoters in stock farming. In addition to this, it includes the results of the two-day meeting in Brussels on 15 and 16 November 2001, Belgium. The collection and publication of these findings supports one of the central aims of the project: to assist in furthering mutual knowledge and understanding of the legal framework and organisations that are tasked with the fight against the illegal use of growth promoters across the European Union and candidate countries.
