# South American avian flu response and poultry market > Live situation record from CLSTR: https://clstr.news/situations/poultry-market-supply-disruptions > Updated: 2026-08-08T20:30:01.000Z. Sources: 23. Developments: 8. In early May 2026 Argentina’s National Service of Agri‑Food Health (Senasa) secured a formal declaration of freedom from highly pathogenic avian influenza (HPAI) from the World Organisation for Animal Health. The autodeclaration enabled Chile and Peru to lift bans on Argentine poultry meat, restoring a key export channel. By early July the country reaffirmed its HPAI‑free status, extending the 180‑day emergency decree, maintaining strict zoning, compartmentalisation and routine farm inspections, and keeping trade open with more than 75 markets. Brazil, meanwhile, confirmed its first 2026 HPAI case in a rescued wild bird and intensified surveillance around a local zoo and nearby farms. Border controls were highlighted when Brazil’s Ministry of Agriculture seized 320 embryonic chicken eggs at Rio de Janeiro’s airport, citing the risk of introducing avian‑influenza pathogens. In August 2026, new isolated cases were confirmed in wild birds. In Chile, the Agricultural and Livestock Service (SAG) reported an H5 HPAI case in a bird in Iquique, Tarapacá; officials maintained that the region remains free of poultry outbreaks. In Brazil, the São Paulo State Secretariat of Agriculture and Supply (SAA) confirmed a second case this year involving a whistling duck found in Ibirapuera Park. Authorities stated there are no commercial poultry establishments within 10 kilometers of the site and that the detection poses no risk to meat and egg exports or the country's sanitary status with the World Organisation for Animal Health. Parallel market pressures emerged in Uruguay, where smuggled chicken products entered the formal sector, and in Bolivia, where a regional egg surplus and road blockades forced producers to launch direct‑sale campaigns using air transport. ## Timeline ### 2026-08-08: Avian influenza confirmed in wild bird at Ibirapuera Park Highly pathogenic avian influenza was confirmed in a wild whistling duck found at Ibirapuera Park in São Paulo, Brazil.
