SPOKANE, Wash. - State health officials are recommending more limits on consumption of fish from Lake Roosevelt and the Spokane River because of pollution.

New tests show that the amount of polychlorinated biphenyls and mercury in fish tissue may be worse than previously thought.

For Lake Roosevelt, burbot and largescale sucker have been added to an earlier advisory covering walleye pike because of mercury levels. The recommendation for walleye is no more than two meals per month and for burbot and largescale sucker no more than four meals per month by women of childbearing age, nursing mothers and young children.

The PCB-related advisory for the Spokane River has been expanded and applies to the general public.

State health officials recommend that no fish taken from the Idaho border to Upriver Dam in Spokane be eaten.

Largescale sucker caught between Upriver Dam and Nine Mile Dam should not be eaten, and all other species taken from the same stretch of the river should be limited to one meal per month.

For the Long Lake reservoir on the river, largescale sucker and brown trout should be limited to one meal per month.
