The Norwegian Food Safety Authority has imposed a hunting ban in several municipalities to prevent the spread of bird flu among captive birds. The areas have seen bird flu in wild birds and have a high density of poultry. The director of the authority, Ole-Herman Tronerud, explained that the virus can lead to significant challenges in egg and poultry meat production. The ban includes species most susceptible to bird flu, but other species can also be infected. The ban may last for the rest of the year.
