DoD Lab Sample Investigation (Anthrax)

About the Response

CDC investigated the unintentional transfer of anthrax from the U.S. Department of Defense (DoD) to labs in multiple states and overseas.

The CDC investigation started after a request for technical consultation from a private commercial lab.

The lab was working as part of a DOD effort to develop a new diagnostic test to identify biological threats.

Although an inactivated agent was expected, the lab reported they were able to grow live Bacillus anthracis.

The investigation included determining if the labs also received other live samples, epidemiologic consultation, worker safety review, laboratory analysis, and handling of laboratory waste.
