Italy has ruled out any danger to public health even though an Italian security expert who tested positive for polonium-210 had recently been in Italy, the Health Ministry said Friday. The ministry said it has been in contact with British health authorities since learning that a urine test for Mario Scaramella, who had met with ex-Russian spy Alexander Litvinenko, had tested positive for the radioactive substance. "As of now, we stress that there are no elements to hypothesize any kind of danger for public health" in Italy, the ministry said in a statement after a special meeting on the case. Litvinenko, who died in London on November 23 of radiation poisoning, blamed Russian President Vladimir Putin for his death in a letter his supporters say he signed on his deathbed. The Kremlin has rejected the accusation.
