Tthe first case of the serious bird flu H5N8 in Danish poultry has been found. These are about 30 ducks in a hobby flock at Aalsgaarde in North Zealand.
It is confirmed by the Food & Drug Administration on Monday morning, they received final test results from the National Veterinary Institute.

The samples originated from a backyard poultry farm in the village Skibstrup by Aalsgaarde in North Zealand. Here died over the weekend about a third of the approximately 30 ducks in the flock.

The tests show that it is the same type of bird flu, which the past ten days was found in Danish wild birds in several places in the country, particularly along the Baltic coast.

To have found bird flu in a Danish hobby flock could have major implications for Danish exports of poultry meat, says deputy head of the Food Administration veterinarian Stig Mellergaard according to a press release.
