The National Service of Health and Agri-Food Quality (Senasa) in Argentina has reported a new case of highly pathogenic avian influenza (HPAI) found in wild birds in the district of General Madariaga, Buenos Aires. This finding came after the agency received reports of mortalities and symptoms in several bird species, including the brown-hooded gull, coscoroba swan, and black-necked swan, from the La Salada Grande Reserve. The confirmation of HPAI raises concerns due to its high mortality rate among birds, including those raised for human consumption, such as chickens.

Despite the detection of HPAI among wild birds, Senasa has assured that the situation does not compromise Argentina's sanitary status or its commercial operations as the country had self-declared itself free of HPAI in September 2025. This declaration is significant for Argentina’s poultry industry and its trade relationships, as HPAI outbreaks in wild birds can lead to heightened surveillance and potential export restrictions.

To prevent further spread of the virus, Senasa has advised all commercial poultry producers to strengthen their biosecurity and sanitation measures. This proactive stance aims to safeguard domestic poultry populations and maintain public health, while also ensuring that Argentina continues to uphold its status as a disease-free nation, which is crucial for the agricultural economy and exports.
