Brazil, the world’s largest chicken exporter, confirmed its first H5N1 avian flu outbreak on a commercial poultry farm in Rio Grande do Sul state, triggering immediate trade restrictions from China and regional bans from other key importers.
The detection at a Vibra Foods supplier facility has put Brazil’s $10 billion poultry export industry at risk, with China imposing a 60-day nationwide ban while Japan, Saudi Arabia, and the UAE restricted imports from the affected state.
The outbreak in Montenegro, Rio Grande do Sul has already led to the culling of 17,000 chickens, with veterinary teams establishing a 10-km quarantine zone around the infected farm.
Brazil’s Agriculture Minister Carlos Favaro assured that protocols are in place to contain the spread, stating officials aim to restore normal poultry trade flows before China’s 60-day window expires. The region accounts for 15% of Brazil’s chicken production and exports, with major processors BRF and JBS operating multiple plants in the state.

The Global Market Impact and the Industry Response
The confirmation has sent shockwaves through global protein markets, with Brazil supplying 35% of world chicken meat exports to 150 countries. ABPA poultry group emphasized Brazil’s rigorous health protocols, while BRF CEO Miguel Gularte expressed confidence in overcoming the crisis quickly.
The outbreak comes as the US poultry industry continues recovering from its own avian flu devastation that eliminated 170 million birds since 2022. By contrast, Argentina successfully contained a 2023 outbreak within weeks, offering a potential roadmap for Brazil’s recovery.
Food Safety Assurances Amid Export Chaos
Brazil’s Agriculture Ministry stressed that H5N1 transmission occurs only through live birds, not via processed chicken products or eggs. “There are no restrictions on consumption of inspected products,” the ministry stated, attempting to prevent domestic panic.
However, the outbreak threatens Brazil’s hard-won reputation as a disease-free poultry exporter, first established after 2023 detections in wild birds failed to impact commercial flocks until now.
With JBS’s Seara brand and BRF plants directly affected, industry analysts warn prolonged restrictions could disrupt global protein supply chains. As Brazil tries its hardest to demonstrate outbreak containment, the coming weeks will test whether the world’s chicken export leader can avoid the catastrophic losses seen in North America’s ongoing avian flu crisis.
