Dutch authorities are trying to stem the spread of bird flu in the country, while a similar bird flu-H5N8 has infected poultry and wild birds in northern Germany.
An order has been issued to kill 200,000 chickens on a farm and a nearby farm in the eastern Netherlands.
* N8 is extremely low risk to humans but can cause significant economic damage.
Health experts say people should avoid touching sick or dead birds, chicken and eggs are safe to eat and if cooked properly, the virus dies.
In addition, there are cases of bird flu in poultry farms in the north-west of England, and 13,000 birds have been reported killed.
The number of animals is being reduced at a farm in Kent, in the south-east of England, where H5N2 influenza was diagnosed this week.
H5N8 has been diagnosed in birds from Russia, and large numbers of birds were slaughtered on farms in the western Russian region of Kostroma late last month to prevent the spread of the virus.
The most recently affected Dutch farms are outside Najmigan, about 30 km from the German border.
Zones have been set up near farms to prevent the spread of the virus, as well as on North German farms in Holland.
According to Germany's state broadcaster NDR, more than a thousand wild birds have died off the coast of Nordfresland, most of them seagulls and ducks.
Bird flu was widespread in Germany between 2016 and 2017, when 900,000 birds were killed nationwide.
The Netherlands, on the other hand, is the largest exporter of poultry and eggs in Europe, employing 10,000 people on 2,000 farms.
A previous outbreak of bird flu in the Netherlands in 2003 killed 30 million chickens, ducks and other birds.
