Bird Flu Reaches Every Continent: What Poultry Traders Need to Know

A virus that is now on every continent

Bird flu is no longer a problem for just a few regions. In mid-2026, the highly pathogenic H5N1 strain known as clade 2.3.4.4b is present on all seven continents. Australia was the last continent without a local case in wild birds, and that gap closed in June 2026.

For poultry buyers and sellers, this matters. When the virus spreads, farms cull their flocks, supply drops, and prices can move quickly. Trade restrictions can also appear with little warning.

Here is where things stand right now, and what it means for the meat trade.

Australia records its first local cases

Australia confirmed its first H5N1 infections in native wild birds this summer. Laboratory tests found the virus in a greater crested tern in the coastal town of Robe, South Australia. This was the first mainland Australian seabird native to the country to test positive, after earlier cases in migratory birds.

By mid-July, Australia had confirmed 12 H5N1 detections across Western Australia, South Australia and New South Wales. Officials said they had found no mass bird deaths and no spread into poultry farms so far, but scientists warned that more cases are likely.

The trade impact was quick. Papua New Guinea, an important buyer of Australian poultry, suspended imports of chicken and eggs after the first cases. On the remote sub-Antarctic Heard Island, an outbreak has killed about 13,000 seal pups, showing how damaging the virus can be to wildlife.

Fresh outbreak in the Philippines

Asia continues to report new cases too. In the Philippines, the World Organisation for Animal Health confirmed an H5N1 outbreak in a backyard flock in Oriental Mindoro province. All 39 birds in the flock were culled to stop the virus from spreading.

The case was small, but it is a reminder that backyard flocks across Asia remain a common entry point for the virus. Dense poultry farming and live-bird markets in the region also help new versions of the virus to form.

The United States keeps losing birds

The United States remains one of the most active hotspots in the world. Recent reports show the pressure has not eased, even in the summer months when cases usually slow down.

Key figures from the latest United States outbreaks include:

Ohio has lost nearly 6 million birds in about one month, mostly on turkey and layer farms.
A single layer farm in Pinal County, Arizona was hit, with about 316,000 birds affected.
New backyard cases were confirmed in Nebraska and Florida.
Since early 2022, the country has lost a record 147 million birds across all 50 states and Puerto Rico.

The virus has also spread to dairy cattle in the United States, with more than 940 herds infected. This jump into cows was not seen in earlier outbreaks and has surprised scientists. Repeated culling has pushed United States egg prices to their largest jump since 1980, and the government has paid out more than 1.19 billion US dollars to farmers for lost flocks.

Europe faces its own pressure

Europe is not spared. The 2025 to 2026 autumn and winter season was among the worst the continent has seen in five years, especially among wild waterfowl. Poland, one of the largest poultry exporters in the world, faced heavy losses early in 2026.

Europe also recorded a worrying first. H5N1 was confirmed in a dairy cow in the Netherlands early in 2026, the first known case in cattle outside North America. This raised concern that the spread into cows seen in the United States could start to repeat in other regions.

Why the virus is so hard to stop

There is still no widely available vaccine or treatment for bird flu in commercial flocks in most major producing countries. When the virus is found in a flock, the usual response is to cull all the birds. This helps contain outbreaks but does not prevent them.

Migratory wild birds carry the virus across long distances, often without showing symptoms. Some evidence also points to the virus spreading between farms through the air, which normal cleaning and protective gear cannot fully block.

What buyers and sellers should watch

Bird flu is now a year-round issue, not just a winter one. For meat traders, that means planning for ongoing risk rather than a single seasonal wave.

Points to keep in mind:

Supply and prices for poultry and eggs can shift fast when large farms are hit.
Import bans can appear suddenly, as the Papua New Guinea decision on Australian poultry showed.
Strong biosecurity and clear health paperwork help keep trade moving when restrictions tighten.
The spread into dairy cattle in the United States and now the Netherlands is worth following closely, as it could affect more than the poultry sector.

Health authorities still rate the risk to humans as low, and no sustained spread between people has been recorded. For the meat trade, the main story remains the effect on supply, prices and cross-border rules.
