Anthrax search closes 11 post offices.
WASHINGTON, Nov. 7 — Nearly a dozen area post offices remained closed Friday while authorities tried to determine whether anthrax was found at a Navy facility that handles mail for federal agencies.
Equipment that routinely monitors the air at the Naval Automated Processing Facility in Washington indicated Wednesday the presence of “small amounts of biological pathogens, possibly anthrax,” said Rachael Sunbarger, a spokeswoman for the Department of Homeland Security.
After the initial field test, eight air samples were sent to Fort Detrick, Md., for testing, according to Lt. Cmdr. Edward Zeigler, a spokesman for the Naval District of Washington. One sample tested positive for anthrax, and seven tested negative, he said.
