In August 2025, Argentina faced a significant challenge when a highly pathogenic avian influenza (H5) outbreak was detected in Los Toldos, a locality in Buenos Aires province. The outbreak threatened the country’s poultry industry, which is a vital sector of its economy. The National Service of Agri-Food Health and Quality (Senasa) immediately implemented strict measures, including culling affected flocks, burying carcasses, and conducting thorough cleaning and disinfection procedures. These actions were essential to contain the virus and prevent further spread.

Declaration of recovery

• Following international protocols, Senasa officially declared Argentina free of avian influenza.
• The declaration was submitted to the World Organisation for Animal Health (OMSA), which is responsible for recognizing and publishing sanitary statuses worldwide.
• This step was crucial, as OMSA’s acknowledgment reinstated Argentina’s credibility in the global poultry market.

Impact on trade

The restoration of avian influenza-free status had immediate economic implications. Argentina resumed negotiations and exports of poultry products, including meat and derivatives, to its international partners. The country’s poultry industry is extensive, with thousands of farms and processing plants, particularly concentrated in provinces such as Entre Ríos and Buenos Aires. In 2024 alone, Argentina processed over 739 million birds, highlighting the scale of its production and the importance of maintaining disease-free certification.
