Commission Decision of 12 May 1993 laying down the criteria for classifying third countries with regard to avian influenza and Newcastle disease in relation to imports of live poultry and hatching eggs (repealed)

4. Around confirmed outbreaks of disease a protection zone with a minimum radius of 3 km and a surveillance zone with a minimum radius of 10 km shall be implemented. In these zones stand-still measures and controlled movements of poultry shall be in force until at least 21 days after the end of the disinfection operations on the infected holding. Before lifting the measures in these zones the authorities shall carry out the necessary inquiries and sampling of the poultry holdings to confirm that disease is no longer present in the region concerned.
