          Note: previously published precise location data of the outbreaks was changed to approximate in follow-up report 3 to insure privacy of the farmers. FUR 24.8.2023: Several HPAI H5N1 outbreaks on fur farms raising arctic foxes, silver foxes, American minks and raccoon dogs have been detected. Wild birds are currently considered the most likely source of the infection, based on epidemiological investigations and sequencing of the viruses. The competent authority has imposed restrictive orders on infected fur animal farms. All minks from the infected farms are culled. Other fur animals from infected farms are culled based on the decisions that are made on a case-by-case basis and do not necessarily apply to all animals on the farm. In addition, samples are taken from infected farms to monitor the course of the epidemic. If the virus is detected, the culling will continue. Veterinary authorities are working in tight collaboration with the public health authority. Improved biosecurity measures and use of personal protection equipment on fur farms are encouraged. FUR 5.10.2023: Starting from 11 September 2023, a new culling policy has been adopted and all animals on HPAI virus-positive farms, including foxes and common raccoon dogs, are culled.

              The bird flu transmission zone will be abolished


              November 1, 2023

              The Finnish Food Agency is abolishing the infection zone established in the summer to prevent the spread of bird flu and its extensions. At the same time, the disease protection regulations that were to be followed in the infection zone will be dismantled. The decision to cancel is supported by the abatement of the disease situation in wild birds and the autumn migration of birds that has already taken place. The decision will enter into force on November 8, 2023.

              The infection zone will be abolished, as the Food Agency estimates that there is no longer a need for it to prevent the spread of bird flu. Since August, only four cases of H5N1 type bird flu in wild birds have been found in the transmission zone. In addition, only isolated cases of wild birds have been found outside the infection zone. Mass deaths of laughing gulls have no longer been observed and the laughing gulls have moved from Finland to wintering areas.

              Based on the situational picture of the disease, the Food Agency has estimated that the bird flu situation in wild birds in the infection zone has eased and the number of wild birds has significantly decreased due to the progress of autumn migration. The Food Agency considers that wild birds no longer pose such an increased risk of the spread of highly pathogenic avian influenza to poultry and other captive birds that maintaining an infection zone is necessary. The bird flu functional expert group has also recommended the abolition of the transmission zone.

              In order to combat highly pathogenic avian influenza, the Food Agency established an infection zone in July under the Animal Diseases Act, which was later also expanded. The infection zone has covered the provinces of Varsinais-Suomi, Satakunta, Etelä Ostrobothnia, Ostrobothnia and Central Ostrobothnia, as well as the provinces of Uusimaa, Kanta-Häme, Pirkanmaa and Päijät-Häme. The regulations of the infection zone were eased already in mid-October, when personal traffic was allowed to the poultry farms, which had previously been limited to only essential visits.

              After the bird flu epidemic that started in the summer, a total of 33 cases of infection have been confirmed in wild birds and the disease has been found in 31 fur farms. Disease control measures continue at fur farms, but no new, suspected bird flu infections have been detected at fur farms since September.

                  Note: previously published precise location data of the outbreaks was changed to approximate in follow-up report 3 to insure privacy of the farmers. FUR 24.8.2023: Several HPAI H5N1 outbreaks on fur farms raising arctic foxes, silver foxes, American minks and raccoon dogs have been detected. Wild birds are currently considered the most likely source of the infection, based on epidemiological investigations and sequencing of the viruses. The competent authority has imposed restrictive orders on infected fur animal farms. All minks from the infected farms are culled. Other fur animals from infected farms are culled based on the decisions that are made on a case-by-case basis and do not necessarily apply to all animals on the farm. In addition, samples are taken from infected farms to monitor the course of the epidemic. If the virus is detected, the culling will continue. Veterinary authorities are working in tight collaboration with the public health authority. Improved biosecurity measures and use of personal protection equipment on fur farms are encouraged. FUR 5.10.2023: Starting from 11 September 2023, a new culling policy has been adopted and all animals on HPAI virus-positive farms, including foxes and common raccoon dogs, are culled.

                        Note: previously published precise location data of the outbreaks was changed to approximate in follow-up report 3 to insure privacy of the farmers. Follow-up report on 24.8.2023: Several HPAI H5N1 outbreaks on fur farms raising arctic foxes, silver foxes, American minks and raccoon dogs have been detected. Wild birds are currently considered the most likely source of the infection, based on epidemiological investigations and sequencing of the viruses. The competent authority has imposed restrictive orders on infected fur animal farms. All minks from the infected farms are culled. Other fur animals from infected farms are culled based on the decisions that are made on a case-by-case basis and do not necessarily apply to all animals on the farm. In addition, samples are taken from infected farms to monitor the course of the epidemic. If the virus is detected, the culling will continue. Veterinary authorities are working in tight collaboration with the public health authority. Improved biosecurity measures and use of personal protection equipment on fur farms are encouraged. Follow-up report on 5.10.2023: Starting from 11 September 2023, a new culling policy has been adopted and all animals on HPAI virus-positive farms, including foxes and common raccoon dogs, are culled. Note on 30/11/2023: Outbreak OB_127861 - 49 - UUSIKAARLEPYY previously reported was deleted in follow-up report No. 20 after further testing confirmed that it was negative. Note on 22/12/2023: After further data received from the country, the number of susceptible animals was lowered in the following outbreaks: ob_127504/35, ob_127506/36, ob_127508/38, ob_127512/42 and ob_127881/56.

Follow-up report on 24.8.2023: Several HPAI H5N1 outbreaks on fur farms raising arctic foxes, silver foxes, American minks and raccoon dogs have been detected. Wild birds are currently considered the most likely source of the infection, based on epidemiological investigations and sequencing of the viruses. The competent authority has imposed restrictive orders on infected fur animal farms. All minks from the infected farms are culled. Other fur animals from infected farms are culled based on the decisions that are made on a case-by-case basis and do not necessarily apply to all animals on the farm. In addition, samples are taken from infected farms to monitor the course of the epidemic. If the virus is detected, the culling will continue. Veterinary authorities are working in tight collaboration with the public health authority. Improved biosecurity measures and use of personal protection equipment on fur farms are encouraged. Follow-up report on 5.10.2023: Starting from 11 September 2023, a new culling policy has been adopted and all animals on HPAI virus-positive farms, including foxes and common raccoon dogs, are culled. Note on 30/11/2023: Outbreak OB_127861 - 49 - UUSIKAARLEPYY previously reported was deleted in follow-up report No. 20 after further testing confirmed that it was negative. Note on 22/12/2023: After further data received from the country, the number of susceptible animals was lowered in the following outbreaks: ob_127504/35, ob_127506/36, ob_127508/38, ob_127512/42 and ob_127881/56.
