Anthrax spores were accidentally shipped from a U.S. military laboratory in Utah to labs in nine states — and an air base in South Korea, officials said Wednesday.
The live samples were sent from the Dugway Proving Ground in Utah by truck, according to authorities.
“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,” said Army Col. Steve Warren, a Defense Department spokesman.
The anthrax samples were shipped from Dugway to government and commercial labs in Texas, Maryland, Wisconsin, Delaware, New Jersey, Tennessee, New York, California and Virginia.
A U.S. official said Wednesday that four people in three commercial labs were recommended for preventive treatment.
A sample was also transported to Osan Air Base in South Korea.
