State takes new look at how much fish is safe to eat


From the shores of Lake Washington to the Duwamish River and other state waters, signs alert locals about toxic fish: Warning: Fish from these waters contain high levels of mercury. Caution: Trout contain high levels of DDT. Advisory: Shellfish contain high PCBs, do not eat! Under state law, Washington's lakes, streams, estuaries and nearshore coastal waters only need to be clean enough for residents to safely consume one serving of fish a month.
