A Pentagon lab accidentally shipped live samples of anthrax to private labs in nine states and Korea, according to ABC News. The shipments, received in the last several days, have prompted an investigation with the CDC to determine if the lethal bacteria was inadvertently sent anywhere else. A senior defense official told The Daily Beast there is no known risk to the general public and no suspected or confirmed cases of anthrax infection in potentially exposed lab workers. The Utah lab that sent the samples was working with the Department of Defense to develop a field-based test to identify biological threats in the environment. "Out of an abundance of caution, DoD has stopped the shipment of this material from its labs pending completion of the investigation," Department of Defense director of press operations, Col. Steven H. Warren said in a statement.
