Live anthrax accidentally sent to nine U.S. laboratories
Live anthrax bacteria was mistakenly shipped to labs in nine states, according to federal health officials.
So far, no one has been sickened by the live anthrax spores, and officials say there is no known risk to the general public.
The shipments, which were supposed to contain inactive anthrax spores, were headed to government and commercial labs in nine states.
The defense department has since halted the remaining shipments of this material pending further investigation.
All samples involved in this latest incident will be securely transferred to the CDC laboratories for further testing.
