Information About Eating Fish From Lexington Reservoir
Why did OEHHA develop the advisory for eating fish from Lexington Reservoir?
OEHHA’s advisory for Lexington Reservoir is based on findings of mercury in fish. The lake is located in Santa Clara County, between Los Gatos and Santa Cruz. This advisory is part of an ongoing effort by OEHHA to provide safe-eating advice for fish in different California water bodies. OEHHA used information from two studies to develop the guidelines for eating fish from Lexington Reservoir.
- Fish are an important part of a healthy, well-balanced diet. The American Heart Association recommends eating at least two servings of fish each week.
- Fish provide a good source of protein, vitamins, and are a primary dietary source of heart-healthy omega-3 fatty acids. Eating low-contaminant fish while pregnant may help the baby’s brain develop.
- Mercury is a metal that comes from natural sources, mining, and air fallout from burning coal and other fuels.
- Too much methylmercury, the form of mercury in fish, can harm the brain, especially in babies and children. Mothers can pass methylmercury to their babies during pregnancy.
- OEHHA compared chemical levels in fish from Lexington Reservoir to acceptable levels of human exposure.
- OEHHA’s consumption guidelines balance the risks and benefits of fish consumption.
