Fish consumption and advisory awareness among low-income women in California's Sacramento-San Joaquin Delta.

Fishing is a culturally important activity to the ethnically diverse population living in California's Sacramento-San Joaquin Delta. Due to runoff from abandoned gold mines, certain Delta fish are contaminated with methylmercury, a neurodevelopmental toxin. A state health advisory recommends limited consumption of certain Delta fish, to be followed in conjunction with a federal advisory for commercial and sport fish.
