The Centers for Disease Control and Prevention is conducting an investigation on four Defense Department labs in a matter of mishandling deadly germs that are used by federal government in their bioterrorism research.

The military studies germs like anthrax, plague and viruses. The research is carried out to know how to defend against the potential use of biological weapons. Currently, there is no report that anyone has been affected due to the mishandling.

But the investigation is being carried out as the bioterrorism experts they have zero tolerance for such incidents, as these organisms are quite dangerous. The CDC investigation led the secretary of the Army to order the four labs to stop working on certain dangerous microbes known as select agents.

The four labs are the Dugway Proving Ground Life Sciences Test Facility in Utah and the three are the US Army Medical Research Institute of Infectious Diseases, the Naval Medical Research Center and the Edgewood Chemical and Biological Center, all are in Maryland.

In May, it was found that the Dugway lab of Utah has transported anthrax by mistake to different labs within the US and to different nations. Spot checks have also been done.
