US disease labs: 'Safety concerns'

US government infectious disease labs mishandled dangerous pathogens five times in the last decade, according to a health agency report.

The incidents were listed in a report on a potential anthrax exposure in June, which occurred when researchers in a high-level biosecurity laboratory failed to follow proper procedures and did not deactivate the bacteria.

CDC Director Thomas Frieden said "we need to look at our culture of safety throughout all of our laboratories".
