Brazil: First outbreak of avian influenza on a commercial farm
16 May, 2025
Brazil has confirmed its first outbreak of highly pathogenic avian influenza (HPAI) H5N1 on a commercial poultry farm. The incident occurred in Montenegro, located in the southern state of Rio Grande do Sul.
As the world's largest exporter of poultry, Brazil's poultry industry holds significant importance on the global stage. While previous HPAI detections in wild birds did not impact the country's trade status, this outbreak on a commercial farm could lead to trade restrictions, depending on international responses.
Brazil reported its first HPAI H5N1 case in wild birds in May 2023, with subsequent detections in backyard poultry.Until now, no cases had been reported in commercial poultry operations.
