Summary
Minnesota, the largest turkey-producing state in the United States, is once again facing highly pathogenic avian influenza (HPAI H5N1). After a five-month respite, a commercial turkey farm in Redwood County confirmed infection, forcing the culling of nearly 20,000 birds and re-establishing a quarantine zone. Farmers who previously relied on enhanced biosecurity and technological tools such as laser deterrents now confront the limits of containment.
Industry leaders are shifting toward vaccination as a medium-term solution. While vaccine development is ongoing, no formulation currently addresses the dominant 2.3.4.4b strain circulating in North America. The USDA has four licensed vaccines for poultry, none yet aligned with this variant. Producers now press Washington for acceleration of trials and deployment. The timeline remains uncertain, with “one to two years” cited optimistically.

Structural Findings
Containment Fragility: Laser deterrents and biosecurity mitigations slowed but did not prevent recurrence.
Culling as Default: Nearly 20,000 birds destroyed, echoing past episodes of large-scale losses.
Regulatory Gap: Four USDA-licensed vaccines exist but do not match the prevailing 2.3.4.4b strain.
Farmer Mobilization: Turkey Growers Association leaders actively lobby in Washington, shifting from resistance to vaccine advocacy.
Economic Stakes: Minnesota’s poultry ecosystem—growers, processors, feed suppliers, logistics—remains structurally exposed.
Evidence Data Points
First detection in commercial poultry since April 2025 (Redwood County).
20,000 turkeys culled; 6-mile quarantine zone imposed.
Laser technology reportedly reduced wild bird interactions and prior infections by ~50%.
USDA: four licensed vaccines exist, none for current strain.
UMN experts: vaccine licensure takes 2–3 years, potentially shortened under emergency authorization.
BBIU Opinion
Avian influenza in Minnesota is not an isolated event but part of a global cycle that exposes the fragility of the poultry trade. The “culling plus biosecurity” model has reached its limit; vaccination is the only sustainable path, yet timelines are slow and coordination weak.
Each outbreak embeds costs into the system: producers pass losses into future sales, importers pay premiums, and poultry prices ratchet upward. What was once the cheapest and most stable animal protein is now volatile, carrying a permanent influenza surcharge.
For food-import dependent countries, this volatility is a direct threat to affordability and stability. Rising poultry prices quickly spill into inflation and political tension. Without faster adoption of vaccines and broader diversification of supply, global food security will remain hostage to the next outbreak.
Annex
What is Avian Influenza?
Avian influenza, also known as bird flu, is a viral disease that primarily affects birds. It is caused by influenza type A viruses, classified according to two surface proteins: hemagglutinin (H) and neuraminidase (N). From this combination come the subtypes, such as H5N1 or H7N9.
Wild birds, especially migratory ducks and geese, often carry the virus without severe illness. The problem arises when the virus reaches domestic poultry—chickens or turkeys—where it can trigger devastating outbreaks. Some forms are of low pathogenicity, producing mild or no symptoms, but highly pathogenic strains (HPAI) can kill large flocks within days.
Transmission occurs through contact with feces, saliva, or secretions from infected birds. Because migratory birds travel long distances, they spread the virus across continents. Once inside a commercial farm, the disease moves rapidly due to the density of animals.
On rare occasions, avian influenza has infected humans, usually after very close contact with sick birds. These cases are uncommon but often severe, with high mortality rates. So far, the virus does not spread easily or sustainably between people.
Beyond health concerns, avian influenza has enormous economic consequences. The standard measure to stop an outbreak is to cull entire flocks, leading to multimillion-dollar losses and disrupting production and export chains. Repeated outbreaks also erode consumer confidence in food safety.
In recent years, one particular subtype—H5N1 clade 2.3.4.4b—has spread globally. It has not only devastated poultry farms but also killed wild birds and crossed into mammals, from foxes to sea lions, and even into dairy cattle in the United States.
Actions When HPAI Is Detected
When highly pathogenic avian influenza (HPAI) is confirmed on a farm, authorities move quickly to contain the outbreak and prevent wider spread. The first step is the immediate quarantine of the site, restricting all movement of animals, people, and equipment. Surrounding farms are placed under heightened surveillance, often within a 6–10 kilometer control zone, with mandatory testing to detect any secondary infections.
The infected flock is then subject to culling, the rapid depopulation of all birds on the premises. This harsh measure—though economically painful—is considered the most effective way to stop the virus before it reaches neighboring farms. Carcasses are disposed of through incineration, burial, or composting under strict biosecurity standards.
Once depopulation is complete, the premises undergo cleaning and disinfection, followed by a period of sanitary fallow, usually 30 to 90 days, before any restocking is permitted. During this time, vehicles, tools, and even clothing used on-site must be disinfected to prevent accidental transmission.
Trade restrictions are also enforced: live bird movements, hatching eggs, and raw poultry products from the affected area are halted, and international partners are notified through the World Organisation for Animal Health (WOAH). In parallel, authorities increase wild bird monitoring, since migratory species are often the original vectors introducing the virus into domestic flocks.
In certain countries, vaccination campaigns may be authorized in high-risk zones, but in the United States vaccination is still under evaluation. For now, Minnesota follows the classic playbook of quarantine, depopulation, and rigorous surveillance—measures that, while effective in containing outbreaks, carry heavy economic and social costs for producers.
Economic Impact
The economic toll of avian influenza goes far beyond the loss of infected birds. When an outbreak is confirmed, entire flocks must be culled. In the most recent case in Minnesota, nearly 20,000 turkeys were destroyed, but in past years the numbers have reached into the millions across the United States. Each culling represents not only the loss of animals, but also the wasted feed, labor, and months of production that went into raising them. Farmers then face an empty period of thirty to ninety days while barns are disinfected and kept fallow, a gap during which no revenue is generated.
Although the USDA provides compensation for birds that are destroyed, those payments rarely cover the full cost of the loss. Producers must still bear the expense of repopulating barns, upgrading biosecurity systems, and sustaining their operations through a period without income. The costs ripple outward: processors, feed suppliers, transporters, and local economies all feel the strain when the supply chain contracts.
At the market level, avian influenza creates volatility. Sudden reductions in poultry supply can push up consumer prices, while export bans imposed by foreign partners amplify the damage. In some outbreaks, entire states—or even the whole country—have faced trade suspensions, cutting off lucrative markets overseas. Consumer confidence also takes a hit; even though properly cooked poultry is safe to eat, recurring headlines about bird flu undermine demand and perception of safety.
The scale of losses can be staggering. Minnesota alone produces over forty million turkeys a year, nearly one-fifth of the U.S. total. A sustained outbreak disrupts not just individual farms, but the backbone of the regional economy. In 2015, the national outbreak cost an estimated $3.3 billion. Since 2022, cumulative losses have already surpassed that figure, making this the costliest animal disease episode in U.S. history.
Ultimately, the economic impact of avian influenza is a cycle of destruction, compensation, and recovery that repeats with every migration season. Without a structural solution—such as an effective vaccination program—Minnesota’s turkey industry remains locked in a pattern of recurring financial damage that undermines both local resilience and national food security.
Leading Global Exporters of Chicken Meat
Today, Brazil is the world’s leading exporter of chicken meat, shipping almost 5 million tons annually to more than 150 countries. The United States follows with about 3.3–3.5 million tons, largely to Mexico, China, and other regional partners. The European Union, led by Poland, ranks third with close to 1.8 million tons, while Thailand specializes in processed chicken exports of about 1 million tons, primarily to Japan and the EU. China, though the largest importer of chicken globally, also exports around 0.4–0.5 million tons of processed products.
In structural terms, Brazil dominates the global supply chain, the U.S. relies heavily on domestic consumption, Poland is the rising power inside Europe, Thailand has carved out a niche in processed poultry, and China plays a dual role as both exporter and the biggest buyer on the world market.
Recent Avian Influenza Reports in Major Exporting Countries
In Brazil, the world’s largest poultry exporter, the Ministry of Agriculture confirmed its first outbreak of highly pathogenic avian influenza in a commercial flock on May 15, 2025, in Rio Grande do Sul. The virus killed more than 7,000 breeder birds, and the remainder of the flock was culled. After strict disinfection and a 28-day observation period with no new cases, Brazil declared itself free of commercial avian influenza again, allowing poultry exports to resume.
The United States continues to report sporadic detections across multiple fronts. Wild birds remain a reservoir, while commercial poultry farms face recurring risks. Since 2024, the virus has also spread into dairy cattle herds, and isolated human cases have been confirmed among farm workers with close contact. As of September 2025, U.S. authorities, including the CDC and USDA, still describe avian influenza as widespread in wild birds and a persistent threat to domestic livestock.
In the European Union, particularly in Poland and the Netherlands—the bloc’s largest exporters—no major commercial outbreaks have been confirmed in the last three months. However, surveillance remains high, especially during the migratory bird season. The European Food Safety Authority (EFSA) continues to monitor wild bird populations, warning that Europe’s dense poultry sector remains structurally exposed.
Thailand, a leading exporter of processed poultry, has not reported major outbreaks in recent months. Nevertheless, authorities remain on alert after Cambodia, its neighbor, confirmed new H5N1 cases earlier this year. Thailand’s position as a regional hub for poultry exports depends heavily on keeping its farms disease-free, and any spillover from neighboring countries would pose a significant risk to its trade.
Taken together, these updates show that avian influenza continues to pressure even the most important poultry exporters. Brazil managed to contain and recover quickly, the U.S. is grappling with a broader, multi-species challenge, Europe is maintaining vigilance, and Thailand remains cautious at its borders. The pattern highlights how global poultry trade is never far from disruption, with each outbreak carrying consequences for both food security and international markets.
Global Supply Chain and Price Impact of Avian Influenza
Before outbreaks, the global poultry market is relatively stable and cost-efficient. Average export prices for frozen whole chicken from Brazil—the world’s largest supplier—hover around $1,200–$1,300 per metric ton, while U.S. broiler exports typically range between $1,400–$1,500 per ton. Supply chains flow smoothly, with Brazil and the United States anchoring trade, the European Union led by Poland supporting regional demand, and Thailand exporting high-value processed products to Asia and Europe.
Once an outbreak occurs, this balance is quickly disrupted. In producing countries, immediate culling removes millions of birds from the system, while import partners often suspend purchases. The U.S. outbreak of 2015, which led to the destruction of more than 50 million birds, drove international poultry prices up by 15–20% within two months, lifting Brazilian export prices above $1,600 per ton. More recently, Brazil’s May 2025 outbreak in Rio Grande do Sul triggered a temporary shock: even though it was contained within weeks, Asian and Middle Eastern buyers shifted orders to the U.S. and Thailand, pushing spot prices to $1,700 per ton.
Domestically, prices can temporarily dip because surplus stock remains trapped behind export bans. Globally, however, the opposite occurs: competition among importers for unaffected supply pushes prices upward. After the 2022–2023 wave of HPAI in the U.S. and EU, average world broiler prices reached $1,800–$1,900 per ton, the highest levels in over a decade.
After containment, trade flows gradually normalize, but prices rarely return to their old baseline. Export bans are lifted slowly, contracts must be renegotiated, and producers face higher ongoing costs for testing and biosecurity. Crucially, affected producers seek to recoup their prior losses—the costs of culling, disinfection, and months without revenue. Even with government compensation, the financial gap is significant, so farms embed these expenses into future sales. The result is a structural pass-through: outbreaks leave a lasting premium in poultry prices, as global buyers indirectly finance past crises through higher forward contracts.
By late 2025, the “new normal” for global poultry is projected at $1,500–$1,600 per ton—about 15–20% higher than the pre-2022 baseline. Each new outbreak not only causes short-term volatility but also ratchets global prices upward, embedding avian influenza as a hidden surcharge within the international poultry trade.
Impact on Food-Import Dependent Countries
For nations heavily reliant on imported poultry, avian influenza outbreaks abroad translate almost immediately into domestic food security pressures. Countries in the Middle East, North Africa, and parts of Asia often source more than half of their chicken supply from exporters like Brazil, the United States, or the European Union. When those suppliers face outbreaks, the consequences cascade.
Price inflation is the first impact. Importers with limited domestic production capacity have no choice but to compete for reduced global supply. When Brazil temporarily lost export certification in May 2025, wholesale chicken prices in the Gulf states and North Africa rose by 10–15% in less than a month. For lower-income households in these regions, poultry is the most affordable source of animal protein, so such increases strain family budgets and amplify inflationary pressure on basic food baskets.
Supply disruption is the second effect. Import bans, imposed either by the exporting country or by cautious import partners, create sudden shortages. Cold storage facilities run low, retailers ration volumes, and governments are often forced to release stocks from strategic reserves if available. In small island economies and food-deficit states, this can translate into outright scarcity.
Strategic vulnerability is the third dimension. Over-reliance on a single exporter magnifies risk: for example, countries like Saudi Arabia, South Africa, and the Philippines have historically concentrated poultry imports from Brazil. A single outbreak there can destabilize their markets unless alternative supply lines—such as the U.S., Thailand, or Ukraine—are mobilized quickly. This diversification, however, comes at a higher price.
Finally, political and social repercussions emerge. Rising chicken prices are visible to consumers, unlike shifts in commodities such as soy or wheat that may remain upstream. In several food-import dependent countries, spikes in poultry prices have triggered public discontent, policy interventions, and emergency subsidies. The political cost of avian influenza thus extends beyond farms and into the streets of Cairo, Lagos, or Manila.
