The authors outline the measures applied in Ireland to prevent the introduction of foot and mouth disease (FMD) from the United Kingdom, France and The Netherlands, to stamp out the disease in Ireland following confirmation of an outbreak on 22 March 2001 and to conduct serological surveillance in order to prove freedom from the disease. Successful control was the result of prompt action and extensive culling in the area around the infected premises. This was achieved by the State Veterinary Service operating with the assistance of the personnel and equipment resources of many Government departments, private industry and private veterinary practitioners, with the co-operation of the farming community and general public. In order to ensure effective use of these resources, good systems of communication and information technology are vital, as are the existence of detailed contingency plans and trained staff.
