"After potentially serious back-to-back laboratory accidents, federal health officials announced Friday that they had temporarily closed the flu and anthrax laboratories at the Centers for Disease Control and Prevention in Atlanta and halted shipments of all infectious agents from the agency’s highest-security labs."

"The accidents, and the C.D.C.’s emphatic response to them, could have important consequences for the many laboratories that store high-risk agents and the few that, even more controversially, specialize in making them more dangerous for research purposes.

If the C.D.C. — which the agency’s director, Dr. Thomas Frieden, called “the reference laboratory to the world” — had multiple accidents that could, in theory, have killed both staff members and people outside, there will undoubtedly be calls for stricter controls on other university, military and private laboratories."
