Bird flu broke out in the Hessian poultry yard

Avian flu in Hesse: Avian flu virus broke out on a poultry farm in Hesse

The bird flu virus H5-N2 was detected in a poultry farm in northern Hesse. The geese of a free-range poultry farm in Hofgeismar in the Kassel district had become infected with the pathogen. "25 ducks, eleven geese and four chickens had to be killed in order to prevent the spread of the infections," reports the vice district administrator of the Kassel district, Susanne Selbert.

"We had to kill 40 of the 90 existing animals and have identified a surveillance zone of one kilometer around the affected husbandry," said Selbert. Only the 50 pigeons of the keeper are spared, but are not allowed to go outside for the time being, which is due to the requirements such as a closed one According to the Kassel district, the surveillance zone affects a further 39 poultry farmers with a total of 783 animals, and transport of the poultry is initially prohibited.

In all potentially threatened attitudes "samples are now being taken in order to rule out that other attitudes are also affected", according to the current announcement. If the examinations are negative 21 days after cleaning and disinfection of the outbreak, the measures can be canceled again, according to the Hessian Ministry of Agriculture. The vice-councilor appealed to the poultry farmers "to keep calm and to support the official veterinarians in their work."

Poultry yard blocked for detection of bird flu virus According to the Kassel district, the bird flu virus was discovered when "the keeper engaged in a poultry breeding association wanted to exhibit some of his animals at a poultry fair in Leipzig." Prerequisites for participation in the fair was proof that none Diseases of the animal are present. Here, "a swab sample, which was examined by the State Office of the Hesse State Laboratory in Gie├čen, showed an infection with the influenza A virus," reports the Vice-State Councilor. After the responsible Friedrich Loeffler Institute on the island of Riems confirmed that it was the "pathogen H5-LPAI", the attitude was immediately blocked by the district veterinary and consumer protection agency, the official announcement. "We are still lucky in misfortune because it is the low-pathogenic variant," emphasized Selbert. According to the specifications of the catalog of measures by the Hessian Ministry of Environment, Energy, Agriculture and Consumer Protection, only a surveillance zone of one kilometer radius had to be defined.

No health risk for the population According to the authorities, the current detection of the bird flu virus does not pose a health risk for humans. Unlike the H5-N1 pathogen, the bird flu virus H5-N2 is not transferable to humans. However, the more pathogenic H5-N2 variants can pose a considerable risk to poultry and, in the worst case, require the culling of millions of animals.

For good reason the bird flu caused by influenza A viruses is a notifiable animal disease. Corresponding pathogens have now been found for the first time in a Hessian poultry farm. Previously, only infections in wild birds were known in Hessen. Although the proven "avian influenza A virus subtype H5" only has low disease-causing properties in poultry, there is "the risk of genetic modification to the highly pathogenic avian influenza A virus subtype H5, avian influenza," the message said of the Hessian Ministry for the Environment, Energy, Agriculture and Consumer Protection.
