The U.S. military inadvertently sent live anthrax samples to research labs in multiple states in the last several days, according to reports.
Two defense officials told CNN that an Army facility in Dugway, Utah, sent out the samples containing the deadly bacteria.
Pentagon spokesman Col. Steve Warren said the government suspects the bacteria was also received by unnamed labs in Texas, Maryland, Wisconsin, Delaware, New Jersey, Tennessee, New York, California and Virginia, the Associated Press reported.
They were supposed to received dead anthrax for research purposes.
The Centers for Disease Control and Prevention was responding to the incident.
"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," Warren said in an email to TheBlaze.
"The DoD lab was working as part of a DoD effort 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," Warren added.
