# Avian Influenza Detections Drop, But Fall Migration Looms | Farm Bureau Intel Markets | American Farm Bureau Federation

> The American Farm Bureau reports that HPAI detections in poultry and dairy have slowed, with one commercial poultry detection and one dairy herd detection in the last 30 days. Since 2022, about 175 million birds and 1,075 dairy herds have been affected. Fall migration is expected to raise the risk of new flare-ups.

## Why it matters

Lower detections ease near-term pressure on egg and turkey supply, but fall migration could bring renewed losses. Markets may price in a seasonal risk premium later in the year.
