# Countries vary widely in early detection of ASF, HPAI: study | Feed Strategy

> New research in Nature Communications finds that countries differ widely in how effectively they detect and notify farmers of African swine fever and highly pathogenic avian influenza outbreaks. The study reports that national income does not explain the differences in surveillance outcomes. The findings focus on surveillance and notification systems rather than specific outbreaks.

## Why it matters

Slow detection and notification can let outbreaks spread further before control measures take hold, which raises the risk of larger supply losses. No immediate price effect is described.
