Overview

• SENASA confirmed highly pathogenic avian influenza H5 at a commercial layer farm in Los Toldos, Buenos Aires, and set 3 km control and 7 km surveillance zones with depopulation and disinfection.
• Argentina notified the World Organisation for Animal Health and paused exports to markets that require a nationally disease‑free status.
• China’s customs posted a suspension of Argentine poultry shipments dated after August 20, cutting access to a key buyer.
• Officials note the affected farm lies outside a major production hub, which may temper immediate domestic supply effects.
• Exports can resume once Argentina self‑declares freedom following cleanup if no further commercial farm cases occur, with zonation accepted by some partners and the sector wary after heavy losses in 2023.
