The Bulgarian Food Safety Agency has reported a bird flu outbreak at a mule duck breeding facility in Brezovo, which houses around 9,000 birds. To contain the disease, measures such as humane culling of infected and contact birds are being implemented. An ongoing epizootic study is tracking the movements of domestic and other birds, as well as products and animal by-products. The agency has confirmed that poultry meat and products from the affected facility pose no risk to human health.
