Bird flu was diagnosed on two poultry farms in Hierden (Gelderland province). It is probably a highly pathogenic variant. To prevent the spread of the virus, approximately 100,000 ducks on one farm and 6,000 bull ducks and 8,300 laying hens on the other are slaughtered by the Dutch Food and Consumer Safety Authority (NVWA). One of the cases concerns the duck farm, which was also closed down on February 4 due to the discovery of bird flu.

The contamination of these farms emerged through the screening of the farms by NVWA due to their location in the 1 kilometer long area of ​​the contamination of a duck farm in Hierden on 7 June 2022.

In the area of ​​1 kilometer around the infected duck farm in Hierden are three other poultry farms, one of which is the farm that was closed down on 7 June, and one is the poultry farm with ducks and laying hens, which has now also been tested positive and will be killed. The third company from the 1 kilometer zone was negative in the screening and has not had direct contact with the infected company and will be barred, selected for bird flu and monitored daily intensively for, among other things, animal health. There are no other poultry farms in the 3 kilometer zone around the infected duck farm. There are 21 companies in the 10-kilometer zone to which the transport ban has been in force since the pollution of the company on 7 June.

In the area of ​​1 kilometer around the infected poultry farm with ducks and laying hens in Hierden are three other poultry farms, one of which is the slaughterhouse on June 7 and a duck farm that has now also been tested positive and will be killed. The third company from the 1 kilometer zone was negative in the screening and has not had direct contact with the infected company and will be barred, selected for bird flu and monitored daily intensively for, among other things, animal health. There is another poultry farm in the 3 kilometer zone around the infected farm, but it is empty. There are 20 companies in the 10-kilometer zone to which the transport ban has been in force since the pollution of the company on 7 June.

Transport ban

Transport bans apply to all birds and hatching and table eggs from a place with birds. The ban also applies to bird manure and spent waste as well as other animals and animal products from poultry farms. In addition, hunting rules apply, eg in this area it is forbidden to hunt ducks or to hunt in areas where this can disturb waterfowl.

National measures

National measures still apply, such as a ban on visiting bird sanctuaries for at-risk birds, unless absolutely necessary. Birds at risk include kept galline-like birds (such as chickens), waterfowl, and ostriches.

The national confinement and screening obligation is also still in full force. The household duty applies to commercial birds, these are brought indoors (except pheasants and ostriches). The protection obligation applies to non-commercial high-risk birds (birds / chickens, (ornamental) waterfowl and ostriches), eg in zoos, kindergartens and owners of birds and chickens, as well as professionally kept pheasants, ornamental waterfowl and ostriches. More information on how this can best be done can be found on NVWA’s website. Prohibition of the display of poultry, waterfowl and ostriches has also been introduced.

Trace investigation

As usual, in connection with the pollution at the sites in Hierden, a tracking study of high-risk contacts is carried out. If necessary, additional measures will be taken in response to the results of the study. Any further action will be reported in an update in this press release and via the online channels of the Ministry of Agriculture, Nature and Food Quality.
