Anthrax found in more government buildings

Anthrax spores were found in yet more government buildings Thursday, with preliminary tests showing anthrax in four FDA mail rooms, the Associated Press reported.

Postal authorities began picking through piles of decontaminated mail in Washington, searching for a possible unopened tainted letter that might help explain why anthrax spores have been found in more than a dozen spots around Washington.

Yet another mail handler was possibly infected. Nationwide, anthrax has killed four people and infected six others with the dangerous inhalation form of the disease. An additional seven people have been infected with the highly curable skin form.

FDA officials said preliminary tests found anthrax spores in mailrooms of four of its Rockville, Md., buildings, with further tests under way.

Meanwhile, three Washington post offices closed for decontamination reopened and city officials reconsidered whether thousands of mail handlers in private offices and outlying post offices need to take preventive medicine, as recommended last week.
