USDA, the Department of the Interior, and the department of Health and Human Resources (HHS) announced an enhanced national framework for early detection of avian influenza (AI) in wild migratory birds in the U.S.

The interagency plan calls for early AI detection in wild migratory birds by: Investigating disease-outbreak events in wild birds,

Expanded monitoring of live wild birds,

Monitoring of hunter-killed birds,

Using sentinel animals, such as backyard poultry flocks, and

Environmental sampling of water and bird feces. USDA plans to collect 75,000 to 100,000 samples from live and dead wild birds, and 50,000 samples of water or feces from high-risk waterfowl habitats across the U.S. -- P. Scott Shearer, Washington, D.C., correspondent
