# Avian influenza: a global epidemic under surveillance | Pasteur.fr

> The Institut Pasteur explainer describes the ongoing H5N1 avian influenza epizootic since 2022, including its spread to dairy cattle. It notes more than 300 poultry farm outbreaks in Europe in the October–November 2025 season, a higher level than prior years but far below the 2022 peak.

## Why it matters

Elevated European poultry outbreaks can tighten egg and poultry supply and add to feed demand uncertainty. The scale is well below 2022, so the price effect is modest.
