GRANTS PASS, Ore. (AP) — Federal scientists have agreed to review the evidence gathered by Oregon agencies after rural residents in Curry County complained they were sprayed by herbicides meant for nearby timberlands and got sick.

The Agency for Toxic Substances and Disease Registry is a branch of the Centers for Disease Control and Prevention. Spokeswoman Susan McBreairty says agency scientists will work with Oregon agencies. The goal is to determine whether the state got enough data for the federal scientists to do what she calls a “meaningful evaluation of community exposure.”

Two dozen residents of the Cedar Valley area north of Gold Beach complained about the spray in October. The watchdog group Beyond Toxics asked the federal agency to get involved.

Residents say they want to know what chemicals they were exposed to.
