Translation of information received on 29 May 2006 from Dr Monique Eloit, Deputy Director General, General Directorate for Food (DGAL), Ministry of Agriculture, Food, Fisheries and Rural Affairs, Paris:
History of Newcastle disease in France
In 2005, France reported three occurrences of Newcastle disease to the OIE. The outbreaks were located in:
St. Mars de Coutais (Loire Atlantique department; affected species: pheasants; date of completion of culling operations: 21 July 2005);
Siracourt (Pas-de-Calais department; affected species: pheasants; date of completion of culling operations: 17 October 2005);
Louvigné-de-Bais (Ille-et-Vilaine department; affected species: pigeons raised for the production of pigeon meat; date of completion of culling operations: 7 November 2005).
For each of these outbreaks, the measures imposed by European Community legislation were immediately implemented and successfully prevented virus dissemination.
All investigations conducted (health visits and laboratory tests) proved favourable for each of these outbreaks. As a result, and in compliance with Community legislation, the restriction measures were lifted on 22 August, 23 November, and 12 December 2005, respectively.
Since that date, no other Newcastle disease outbreaks have been detected in France.
Conclusion
Under the terms of Article 2.7.13.2. of the OIE Terrestrial Animal Health Code, a country in which a stamping-out policy is practised may be considered Newcastle disease free six months after the culling of the last affected animal.
Culling operations were carried out and completed on 7 November 2005, for the last confirmed outbreak.
France therefore recovered its status as a Newcastle disease free country on 7 May 2006.
