The 2018 Open Session of the EuFMD Standing Technical Committee was held in Borgo Egnazia - Italy, 29-31 October 2018 . The session theme was on global vaccine security The European Commission for the Control of Foot-and-Mouth Disease (EuFMD), one of FAO’s oldest Commissions, came into being on the 12th June 1954, with the pledge of the sixth founding member state to the principles of a coordinated and common action against Foot-and-mouth Disease.
