A suspected outbreak of avian influenza has been reported in the Regensburg district of Bavaria, leading to the preventive culling of 60,000 chickens. In Switzerland, the disease has been detected in black-headed gulls in the cantons of Zurich and St. Gallen. Both countries' veterinary and food safety offices are implementing measures to limit the spread of the disease and protecting domestic poultry. The risk of the disease spreading to poultry is currently assessed as low in Switzerland due to the breeding behavior of gulls.
