New cases reported despite easing in other European regions

The avian influenza situation in Europe is evolving, with Hungary and Poland recently confirming new outbreaks in their poultry sectors. This development comes even as other parts of the region see a decline in cases, prompting changes in biosecurity measures.

Regional Context

While the overall risk of highly pathogenic avian influenza (HPAI) in Europe appears to be diminishing with the arrival of spring, Hungary and Poland have reported fresh outbreaks. These incidents occurred between April 24 and May 7, affecting six farms in Hungary and four in Poland. In contrast, regions such as the Republic of Ireland and Northern Ireland are lifting compulsory poultry housing measures, reflecting a more optimistic outlook.

Market Implications

The persistence of avian flu in Hungary and Poland poses significant challenges for the poultry industry, impacting supply chains and potentially affecting market prices. In Hungary, the outbreaks have been concentrated mainly in the south, affecting foie-gras ducks and meat turkeys, while Poland's recent cases involved broilers, laying hens, and mixed poultry. The cumulative impact on Poland's poultry sector has been severe, with over 7.7 million birds affected by mortality and culling since the onset of the outbreaks.

Biosecurity Measures

Despite the easing of restrictions in some areas, authorities stress the importance of maintaining stringent biosecurity measures to prevent further spread.

"It is important to note that avian influenza is still a risk"

Stated the Republic of Ireland’s Minister for Agriculture, emphasising the need for continued vigilance.

Wild Bird Cases

In addition to domestic poultry, HPAI has been detected in wild birds across nine European countries, with 532 outbreaks reported in 2025 alone. This includes a variety of HPAI strains, such as H5N1 and H5N5, underscoring the virus's adaptability and the ongoing threat it poses to both wild and domestic bird populations.

As the situation develops, stakeholders in the poultry industry must remain alert and responsive to changes in disease dynamics to mitigate risks and ensure supply chain stability.
