THE US military is now scrambling on its efforts to retrieve live anthrax samples it accidentally shipped to laboratories in nine states and one army base in South Korea, reports said.

The anthrax samples were originated from Dugway Proving Ground, a US army laboratory facility about 85 miles southwest of Salt Lake City, Utah.

Chemical and biological weapon testing of the US government is often conducted in the said facility.

Pentagon spokesperson Col. Steve Warren, in a statement, said they have already coordinated with the Centers for Disease Control and Prevention to investigate on the incident.

The nine US states where live anthrax samples were inadvertently distributed include New Jersey, Virginia, Texas, Tennessee, California, Delaware, Wisconsin, New York, and Maryland.

While the Joint United States Forces Korea Portal and Integrated Threat Recognition Program at Osan Air Base also reportedly received sample of the known powerful bioweapon.

“The sample was destroyed in accordance with appropriate protocols,” said Warren.

“There is no known risk to the general public, and there are no suspected or confirmed cases of anthrax infection in potentially exposed lab workers,” added Warren in a statement.

Personnel who handled the anthrax samples have been under post-exposure treatment while its laboratory was decontaminated, Pentagon reported.

The US army also said it has already conducted inventory of the anthrax.
