Brazil's Ministry of Agriculture has declared a zoosanitary emergency in Montenegro, Rio Grande do Sul, due to the detection of highly pathogenic avian influenza (HPAI) in a commercial poultry breeding farm, marking the first case in the country's commercial system. The emergency decree, effective for 60 days and with a 10 km radius around the affected farm, is part of a larger nationwide state of emergency declared on April 4, following the detection of the virus in wild birds, and is aimed at containing the spread of the disease. The ministry emphasizes that the disease is not transmitted through poultry meat and eggs, and has initiated measures in line with the National Contingency Plan. This development occurs amidst ongoing outbreaks of avian flu in Brazil since 2023, primarily affecting wild birds.
