Dr. Colker said that an initial battery of tests on Mr. Piven had shown normal results. But after Mr. Piven said he was a frequent sushi eater who consumed fish about twice a day, and that he used herbal remedies, Dr. Colker tested him for heavy metals.

Dr. Colker said that these tests revealed “a very, very elevated level of mercury” in Mr. Piven’s blood, adding that it was five to six times the upper limit that is typically measured. Left untreated, Dr. Colker said, the condition could result in heart problems, cognitive problems, renal failure and, in very extreme cases, death. He said that he told Mr. Piven he could continue in the show, but only with extreme caution.

... ahhhh damn.
