The outbreak has been detected at a poultry farm in Ter Aar, around 25km from the original outbreak – outside the 10km surveillance zone. The strain has been confirmed as H5, but tests are still ongoing as to whether it is the same strain (H5N8) as discovered in Hekendorp a week ago.
The process of culling all 43,000 susceptible laying hens began immediately and a national ban on the transportation of poultry and related products has been reintroduced. A 10km surveillance zone has now been established around the infected farm in Ter Aar, which contains four other poultry farms.
A national ban was originally imposed on Sunday 16 November following the discovery of the H5N8 strain of bird flu at an egg farm in Hekendorp.
The transportation of all poultry, other live birds, eggs and waste material was restricted, but on 18 November the ban was lifted after minister for agriculture Sharon Dijksma informed the House of Representatives there had been no new cases detected on farms within a 10km radius of the original outbreak, following a process of sampling.
A nationwide order requiring poultry and other live birds to be housed indoors remains in force, and will do for a minimum period of 30 days until 18 December.
It is expected that the results of tests confirming the exact strain will be released tomorrow.
