A total of 122,000 birds from two commercial farms in Argentina have been culled due to an outbreak of avian influenza (AI) H5, as confirmed by the National Agri-Food Health and Quality Service (Senasa). This marks the second case in Patagonia, following an outbreak in Río Negro that resulted in the culling of over 180,000 broiler chickens. The outbreak first affected wild and backyard birds, indicating that the disease has spread from migratory birds. So far, the disease has been detected in 39 locations across the country, affecting various types of birds. Measures such as sanitary emptying, control of entry and exit points, and raking are being implemented to contain the spread of the disease.
