Bird flu found on third Dutch farm

The Dutch economic affairs ministry confirmed that a second bird flu outbreak detected on Thursday on a farm at Ter Aar, close to the first case, was the highly pathogenic H5N8 strain, previously detected only in Asia.

Some strains of avian influenza are fatal for chickens, and pose a health threat to humans, who can fall sick after handling infected poultry.

Dutch authorities have said human infection can only occur following "intense and direct contact" with infected birds.

The latest outbreak was found on a small farm in Kamperveen, around 100 kilometres (65 miles) north of the two other outbreaks, the economic affairs ministry said in a statement.

"The bird flu virus has been detected on a farm with around 10,000 chickens," it said.

The birds will be destroyed and the farm disinfected, the ministry said, with tests being carried out to establish if the strain is H5N8.

Dutch officials on Sunday banned the transport of poultry around the Netherlands after the discovery of a highly infectuous strain of bird flu following outbreaks of similar strains on the virus in Britain and Germany.

Some 150,000 birds were destroyed at the farm in Hekendorp, which lies about 25 kilometres southeast of Ter Aar.

The H5N1 strain of bird flu has killed more than 400 people, mainly in southeast Asia, since first appearing in 2003. Another strain of bird flu, H7N9, has claimed more than 170 lives since emerging in 2013.

The H7N7 strain of avian flu severely hit the Netherlands in 2003 with health authorities destroying some 30 million birds in an effort to quash an outbreak.
