For the eighth time this season, France finds itself at the edge of a familiar grief: the return of H5N1 bird flu, this time to the Gers region of the southwest, where the foie gras industry has long shaped the land and its people.

Bird flu returns to France's foie gras region; mass duck culling planned
Mass culling of duck flocks affecting agricultural livelihoods and food production in the foie gras industry.
The virus has found its way south, into the heart of an industry that depends on keeping large numbers of birds in close proximity.
Mark
Why does bird flu keep coming back to the same region?
Mimi
Because Gers is where the ducks are. Foie gras production concentrates birds in a relatively small area, and once the virus gets in, it moves through that density quickly. It's not that the region is uniquely vulnerable—it's that the industry itself creates the conditions the virus loves.
Mark
So the culling of eight neighboring farms—is that precautionary, or have they already found the virus there?
Mimi
Precautionary. The seven farms around the infected one haven't tested positive yet, but they're close enough that the virus could have already arrived. By the time you confirm it, it's usually too late. So they kill first.
Mark
What does a farmer do when their entire flock is ordered slaughtered?
Mimi
They comply. There's no choice—it's the law. But the economic hit is immediate and total. No income from that cycle, no product to sell, no way to recoup feed costs or labor. For a small operation, one culling can mean the difference between staying in business and closing.
Mark
Why hasn't France developed a vaccine?
Mimi
Vaccines for poultry exist, but they're not widely used because they complicate trade. If you vaccinate, other countries assume your birds might be infected and restrict imports anyway. So the industry and governments have stuck with culling as the faster, cleaner solution—at least on paper.
Mark
China's ban—is that still in effect?
Mimi
Yes. It was imposed over a year ago and hasn't been lifted. One outbreak can trigger a ban; lifting it requires sustained proof that the disease is under control. This new case in Gers doesn't help that case.
Il Polso
- H5N1 has breached the foie gras heartland for the first time this season, striking a duck farm in Gers and threatening an industry built on the fragile logic of dense, carefully timed bird populations.
- Authorities have ordered the immediate slaughter of all ducks on the infected site and seven surrounding farms, deploying the blunt but necessary firebreak that containment demands.
- This is the eighth outbreak in France this season alone, and it arrives against a backdrop of avian influenza spreading rapidly across Europe and Asia — suggesting the virus is far from finished.
- China's import ban on French poultry, imposed after last winter's devastating wave that killed over three million ducks, remains in force, compounding the economic pressure on producers already bracing for another crisis.
- If the firebreak fails and the virus moves deeper into the southwest, France risks another season of mass culling, prolonged trade restrictions, and existential strain on the small and mid-sized farms that sustain the foie gras tradition.
For the eighth time this season, France finds itself at the edge of a familiar grief: the return of H5N1 bird flu, this time to the Gers region of the southwest, where the foie gras industry has long shaped the land and its people. Authorities have ordered the culling of ducks on the infected farm and seven neighboring properties, reaching for the only tool that reliably slows the virus. The outbreak arrives as avian influenza moves broadly across Europe and Asia, and as China's import ban on French poultry — a wound from last winter's wave — remains unhealed, reminding us that a disease born on one farm can reshape the economics of an entire industry for years.
The disease has come back to southwestern France. On December 17th, the farm ministry confirmed that highly pathogenic H5N1 bird flu had been detected on a duck farm in Gers — the region whose name is nearly synonymous with foie gras — marking the eighth outbreak of the season and the first to reach this particular heartland since the previous winter's devastation.
The response is immediate and unsparing. Every duck on the infected farm will be slaughtered, along with all birds on seven neighboring properties. The goal is a firebreak — a hard boundary drawn in loss — to prevent the virus from moving deeper into the dense web of farms that supply the foie gras industry. It is the only reliable method available; H5N1 in poultry is often fatal, and no vaccine exists.
France has been here before. Last winter, more than three million ducks were culled in a single wave. That outbreak triggered trade consequences that outlasted the disease itself: China's ban on French poultry imports remains in place a year later, a persistent economic bruise on an industry still recovering.
The timing sharpens the concern. The previous seven outbreaks this season had all occurred in northern France, in regions less dependent on duck farming. The arrival of the virus in Gers signals something more threatening — a southward movement into territory where the production cycle is precise, the farms are numerous, and the margins are thin. A forced culling disrupts breeding schedules, market supply, and the careful economics that keep smaller operations alive.
For now, authorities are focused on containment, watching the neighboring farms and hoping the firebreak holds. If it does not, France may face another winter of mass culling, another year of closed markets, and another season of loss for farmers who have already paid dearly.
The disease has returned to southwestern France. On Friday, December 17th, the country's farm ministry announced that highly pathogenic H5N1 bird flu had been detected on a duck farm in Gers, a region in the country's southwest known for producing foie gras—the prized liver pâté that commands premium prices across Europe and beyond. The discovery marks the eighth outbreak France has recorded this season, and the first to strike the foie gras heartland since last winter, when the virus decimated duck flocks across the region.
The response will be swift and total. Authorities have ordered the slaughter of every duck on the infected farm, along with all birds on seven neighboring properties. The culling is meant to create a firebreak, to stop the virus from spreading further into the dense network of duck farms that supply the foie gras industry. It is a blunt instrument, but it is the standard one: when H5N1 takes hold in poultry, the disease is often fatal, and there is no vaccine. Killing the birds is how the industry and governments have learned to fight back.
This is not France's first battle with the virus. A year earlier, in the winter of 2020, the country had slaughtered more than three million ducks in an effort to contain a previous wave. That outbreak had been severe enough to trigger international trade restrictions. China, a major buyer of French poultry products, had imposed a ban on imports that remained in place even now, a year later—a reminder that bird flu's damage extends far beyond the farm gate.
The timing is particularly difficult. Severe avian influenza has been spreading across Europe and Asia in recent weeks, suggesting the virus is on the move again. The previous seven outbreaks this season had all occurred in northern France, in regions less dependent on duck farming. This new case in Gers signals that the virus has found its way south, into the heart of an industry that depends on keeping large numbers of birds in close proximity. The foie gras production cycle requires specific timing and management; a forced culling disrupts everything—breeding schedules, market supply, the careful economics that keep small and mid-sized farms viable.
Bird flu cannot be transmitted to humans through food, and the risk of human infection remains low. But epidemiologists have noted the occasional human case, enough to keep the disease on the radar of public health officials alongside agricultural authorities. For now, the focus remains on containment: slaughter the infected flocks, monitor the neighboring farms, hope the firebreak holds. If it does not, if the virus continues to spread south and east, France may face another winter of mass culling, another year of trade bans, and another season of economic loss for farmers who have already endured one such crisis.
