Pesticides may be endangering salmon

A federal agency says three pesticides commonly used on farms and orchards are endangering the survival of Pacific salmon.

The National Marine Fisheries Service says the chemicals are getting into streams at levels high enough to kill protected salmon.

Experts say the pesticides interfere with a salmon's sense of smell, which makes it harder for them to avoid predators, find food, and locate their native spawning streams.

The National Marine Fisheries service has until the end of October to work with the Environmental Protection Agency to find new ways for farms to safely use the pesticides.
