HPAI Enters Peak Migration Season with Active Outbreaks Across North America and Europe
HPAI H5N1 spreads across North America and Europe during peak wild bird migration season. Active outbreaks across 14 US states and multiple EU countries disrupt poultry supply chains.
Highly pathogenic avian influenza is circulating across eleven European countries and multiple US states as spring migration reaches its seasonal peak - the highest-risk window for commercial poultry.
HPAI is no longer a periodic shock to poultry markets — it is a recurring seasonal variable with predictable supply and pricing consequences. The spring 2026 migration window is active and escalating. With simultaneous outbreaks across Northern Hemisphere supplier regions, Brazil's position as the world's de facto HPAI-free swing supplier of poultry protein continues to strengthen by default.
SIGNAL
Highly pathogenic avian influenza (HPAI H5N1) is circulating actively across North America and Europe as the Northern Hemisphere enters the peak spring migration window — historically the highest-risk period for commercial flock transmission. In the United States, commercial flock detections have been confirmed in Wisconsin, Indiana, North Carolina, Iowa, Michigan, Pennsylvania and South Dakota in 2026 to date. A single outbreak in Hyde County, North Carolina resulted in the loss of 3.3 million laying hens. Wisconsin has suspended all poultry exhibitions across 20 southern counties through 10 May 2026. In Europe, eleven countries have confirmed commercial flock infections, with 435 cases reported to the EU notification system through early February. Germany has logged 36 commercial outbreaks; Italy confirmed infections across four regions including a single laying hen flock of 210,000 birds. Wild bird surveillance has identified an H5N6 variant in Portugal — a strain not previously detected in the country.

- Germany: 36 commercial poultry outbreaks confirmed in 2026 to date across seven federal states (Friedrich-Loeffler Institute via WOAH)
- North Carolina: 3.3 million laying hens lost in a single Hyde County outbreak; Indiana has recorded nine commercial flock infections in 2026 (APHIS / WATTPoultry)
- Wisconsin DATCP suspended all poultry shows, exhibitions and movement events across 20 southern counties through 10 May 2026, citing active migration monitoring (DATCP)
- FAO Meat Price Index, February 2026: poultry prices rose marginally on firm import demand in several markets, partially offset by ample supplies in key producing countries — a balance that tightens materially if spring losses escalate (FAO)
- CDC maintains public health risk assessment as low as of 6 March 2026; human cases remain sporadic among poultry and dairy workers in direct animal contact roles (CDC)
IMPLICATION
A high-loss spring migration cycle would constrain US and European commercial layer and turkey supply into Q3 2026, sustaining egg price pressure and tightening poultry export availability at a time when global import demand remains firm. For buyers in Southeast Asia and the Middle East — markets that draw significant poultry volumes from both the EU and the US — simultaneous active HPAI in both primary Northern Hemisphere supplier regions concentrates sourcing dependency on Brazil. Brazil's HPAI-free status is not a temporary advantage; it is a structural commercial proposition that deepens with every Northern Hemisphere outbreak cycle. The H5N6 detection in Portugal is an early-stage signal worth monitoring — novel strain variants in wild bird populations have historically preceded more disruptive commercial incursion events.

- US and EU egg processors and foodservice operators face sustained input cost pressure as layer flock losses compound through Q2-Q3; North Carolina's 3.3 million bird loss alone removes meaningful shell egg capacity.
- Poultry importers in the Gulf States and ASEAN markets face narrowing supplier optionality and freight cost inflation as Brazilian volumes stretch to fill Northern Hemisphere gaps.
- European turkey and duck processors entering summer production cycles carry elevated biosecurity costs and potential throughput constraints in Germany, France, and Poland.
- Winners: Brazilian exporters (BRF, JBS, Seara) gain pricing power and volume share by default; cold chain logistics operators serving South America-to-Asia/MENA lanes see utilization gains.
- Losers: US and EU layer operators absorb cull costs and insurance gaps; egg-intensive food manufacturers (bakery, pasta, prepared foods) in affected regions face margin compression; importers locked into Northern Hemisphere contracts carry supply risk.
