A severe strain of H5N8 bird flu that has hit several countries in Europe leading to the culling of thousands of poultry has been detected in 20 wild ducks in northern France over the week-end, the farm ministry says.
Local authorities increased surveillance in the area, the ministry said in a statement on Monday, stressing that the virus had not been found in a domestic farm.
Bird flu outbreaks in southwestern France earlier this year had lead to the total halting of output in the region and importing restrictions from trading partners.
The H5N8 bird flu virus has never been found in humans.
