Anthrax Detection: DHS Cannot Ensure That Sampling Activities Will Be Validated

In September and October 2001, contaminated letters laced with Bacillus anthracis were sent through the mail to two U.S. senators and members of the media. Postal facilities in New Jersey, Washington, D.C., and elsewhere became heavily contaminated. The anthrax incidents highlighted major gaps in civilian preparedness to detect anthrax contamination in buildings. GAO was asked to describe and assess federal agencies' activities to detect anthrax in postal facilities, assess the results of agencies' testing, and assess whether agencies' detection activities were validated.
