"But many epidemiologists and public health experts say poor handling inside laboratories, rather than bioterror, is the real threat. More than 100 accidents in high-security labs took place between 2003 and 2009, involving everything from flu-infected ferret bites to dropped vials of encephalitis, slips with Ebola needles and lost shipments of bubonic plague. The 1977 “Russian flu” epidemic may have involved a lab escape. Less accidentally, anthrax used in the 2001 attacks almost certainly originated in U.S. military laboratories."
Excuse me for a moment here, but what?!
