11/24/2020: 

Between November 6th and 22nd Avian influenza (H5) has been found at:

• a laying farm in Hekendorp (municipality of Oudewater in the province of Utrecht)
• a farm housing broilers in Witmarsum (in the province of Friesland)
• a duck farm in Terwolde (municipality of Voorst in the province of Gelderland)
• a laying farm in Lutjegast (municipality of Westerkwartier in the province of Groningen)
• backyard chickens in Middelie (municipality of Edam-Volendam)
  

It probably concerns a highly pathogenic variant of avian influenza. The poultry will be culled in order to prevent the virus from spreading. The culling process will be conducted by the NVWA (Dutch Food and Consumer Product Safety Authority).

Wild birds can transmit avian influenza. The NVWA website has a map showing you where infected dead wild birds have been found in the Netherlands.

Supplementary national measures

All the current national measures, such as compulsory indoor segregation for commercial poultry, remain in full force. The same applies to the compulsory measures for duck farms and the use of bedding. The following measures also apply:

1. The hygiene protocol for visitors has been extended. This means, for example, that visitors may only enter the broiler house or farmyard after implementing strict hygiene measures.
2. National measures will be taken for the transport of commercial poultry between farms, and for transport of ducks and turkeys to abattoirs. This transport is permitted, as long as:
   1. the transport takes place in accordance with a hygiene protocol;
   2. the poultry or ducks or turkeys are accompanied by a declaration, not older than 24 hours, by a vet that the poultry or ducks or turkeys held at the farm from which transport is taking place, have not shown any symptoms of disease, based on a clinical inspection;
3. There are also measures in place for the transport of cattle, day-old chicks, manure, eggs, animal fodder, milk or bedding to or from a commercial duck or turkey farm. This transport is permitted, as long as:
   1. the route to be taken by the transporter visits no more than one commercial poultry farm;
   2. the transport takes place in accordance with a hygiene protocol.
4. Zoos, petting zoos and owners of non-commercial birds are obliged to segregate their poultry and waterfowl in order to prevent these animals from coming into contact with wild waterfowl and their faeces.
5. Public display of show poultry and waterfowl is prohibited.
