Rio Grande do Sul registers case of avian influenza in backyard poultry.

The government of Rio Grande do Sul confirmed this Monday (20) the detection of an outbreak of Highly Pathogenic Avian Influenza (HAI), known as avian flu, in subsistence poultry in the municipality of Coqueiros do Sul, in the northwest region of the state. According to a statement from Secretariat of Agriculture, Livestock, Sustainable Production and Irrigation (Seapi), the case was confirmed by Federal Laboratory for Agricultural Defense of Campinas (LFDA-SP) Last Friday (17). The state government highlighted that, since it involves subsistence poultry — raised in backyard systems — the episode does not alter the sanitary condition of Rio Grande do Sul and Brazil as free from Highly Pathogenic Avian Influenza in commercial poultry farming, and there are no impacts on the trade of chicken meat and other poultry products. As a containment measure, the Official Veterinary Service of Rio Grande do Sul (SVO-RS) will carry out inspections on rural properties and farms located within a 10-kilometer radius of the outbreak, in addition to intensifying surveillance, sanitary education and awareness actions for producers. In May 2025, Brazil registered a case on a commercial farm in Montenegro (RS), in which, after 28 days without new outbreaks of the disease in these types of establishments, the country declared itself free of avian influenza on commercial farms.
