The Wyoming Department of Health has issued an advisory for Wyomingites regarding mercury in some wild-caught freshwater fish.
Species identified as having high mercury content include channel catfish, sauger, and walleyes from Big Horn, Pathfinder, Boysen and Seminoe Reservoirs. Women of childbearing age or who are pregnant or nursing, as well as kids under 15 years of age, should not consume any fish considered to be high in mercury. Everyone else should limit their servings to one to two servings a month.
Low mercury fish include Wyoming-caught trout, farm-raised talapia and catfish. Women and children can safely consume low mercury fish twice a week, and “prudent consumption" is advised for all others.
In general, Wyoming fish are low in mercury compared to other areas in the nation.
The advisory is attached below.
