U.S. Military Mistakenly Transfers Live Anthrax

A U.S. defense official said on Wednesday that the U.S. military mistakenly sent at least one live anthrax sample to a private laboratory in Maryland and possibly sent others to eight other states. The official said the samples were meant to be sent in an inactive state for research purposes and added the samples were now believed to be secure. The Pentagon confirmed an investigation into the incident was underway and said there was no public health risk. It was not immediately clear if anyone in those laboratories might have been exposed before learning they had live, as opposed to inactive samples.
