## Summary

As of June 2026, [H5n1](/ar/entity/h5n1) remains entrenched in US poultry and [Dairy Cattle](/ar/entity/dairy-cattle). USDA
confirmations have reached more than 500 dairy herds across 15 states, with California
about 291; roughly 15.2 million birds have been culled in 2026, keeping retail egg prices
elevated, typically within 6-8 weeks of depopulations. CDC counts 71 human cases since
February 2024, mostly mild and farm-linked, calling public risk low. Research is probing
transmission via flies, milk handling and bovine semen. Europe has eased some controls —
Spain lifted poultry confinement on 1 April 2026 — signalling regional divergence.

## Why it matters

The ongoing cull plus 500-plus affected herds sustain elevated [US](/ar/entity/united-states) egg and
poultry prices and a low-but-watched human-spillover risk — a slow biosecurity drag on
[Food Prices](/ar/entity/food-prices).
