The U.S. military said on Friday it discovered even more suspected shipments of live anthrax than previously thought, both in the United States and abroad, and ordered a sweeping review of practices meant to inactivate the bacteria.
The Pentagon said a total of 11 states, two more than it first acknowledged, had received "suspect samples," as did Australia and South Korea. It had previously only identified a foreign shipment to a U.S. air base south of Seoul.
"There is no known risk to the general public and an extremely low risk to lab workers," the Pentagon said in a statement.
