Countries enforcing a nationwide ban include China, the European Union, Mexico, and South Korea, among others. Those applying regional restrictions include the UK, Ukraine, and Cuba, while Japan and Saudi Arabia limited bans to the specific municipality. These partial bans reflect adherence to the World Organization for Animal Health’s regionalization principle, which Brazil’s government is actively promoting to minimize broader economic impacts.

The outbreak comes at a challenging time for Brazil’s poultry sector, particularly in Rio Grande do Sul, which produces 15% of the country’s chicken and is still recovering from severe floods in 2023. The Ministry of Agriculture continues diplomatic efforts, especially with China, to lift full bans and restore exports from unaffected regions.
