The Mpumalanga Department of Agriculture has culled over 20 thousand chickens from a farm in Villiers on the banks of Vaal River bordering the province with Free State. This after samples collected from the farm tested positive for a Highly Pathogenic Avian Influenza, H5N8 also called bird flu virus. Dr Mpho Maja, Director of Animal Health at the Department of Agriculture, Forestry and Fisheries says in a bid to control the spread of the virus the department has decided to ban the sale of live chickens throughout the country. Meanwhile, in a statement the department says no human cases of infection with avian flu have been reported.
