The present Decision establishes protection measures to prevent the spread of avian influenza within the European Community, in addition to those foreseen in the framework of Council Directive 2005/94/EC. These measures shall be applied in cases of highly pathogenic avian influenza in poultry in the territory of a Member State, caused by influenza A virus of subtype H5 suspected or confirmed to be of the neuraminidase type N1, in order to prevent the spread of avian influenza into the disease free parts of the Community through movement of poultry, other birds and derived products.
