(Salem, OR)  --  Oregon is joining 22 states in calling on the federal government to set standards for toxic metals in baby food.  The proposal calls for interim limits on arsenic, lead, cadmium, and mercury.  The level of arsenic in infant rice cereal would be reduced from its current level.  Baby food manufacturers would also get guidance for toxic metal testing.  The U.S. Food and Drug Administration and the U.S. Department of Agriculture would need to set the new rules.
