The symposium was organised by Danish Institute for Food and Veterinary Research and Danish Insti- tute of Agricultural Science with the support of the World Health Organization. A total of 140 par- ticipants from 12 countries participated in the symposium, which included 32 scientific presenta- tions in 6 sessions with the following headings: Effects of the termination of antimicrobial growth promoter use on bacterial resistance to antimicrobials Effects of the termination of antimicrobial growth promoter use on animal welfare and pro- ductivity Consequences of termination of antimicrobial growth promoters use for animal health and the use of antimicrobials in food animals for therapy and prophylaxis Effects of the termination of antimicrobial growth promoter use on food prices and the com- petitiveness of agricultural industries Consequences of termination of antimicrobial growth promoters use for the environment Alternatives to the use of antibiotic growth promoters International speakers This report contains all working papers prepared by the presenters in the symposium. The papers are also available at www.who.int In conjunction to the symposium the World Health Organization organised an independent expert review of the Danish experiences. The expert reviewers report is also available from www.who.int This report has been prepared for publication by Susanne Carlsson DFVF and Lotte Tind Pedersen DIAS.
