Army chief: Human error at Army lab probably was not the cause of mistaken anthrax shipments

The Army's top general says human error probably was not a factor in the inadvertent shipping of live anthrax to research laboratories.

Gen. Ray Odierno (oh-dee-EHR'-noh) is the Army chief of staff. Odierno told reporters Thursday the problem may have been a failure in the technical process of killing, or inactivating, anthrax samples.

He says the Centers for Disease Control and Prevention is looking at that aspect of what went wrong at Dugway Proving Ground, the Army installation in Utah that sent the anthrax to government and commercial labs in nine states across the U.S. and to an Army lab in South Korea.

The Pentagon disclosed on Wednesday that at least one of nine labs in the U.S. that received anthrax got live rather than dead bacteria.
