U.S. Centers for Disease Control and Prevention (CDC) Director Tom Frieden (C) testifies at a House Energy and Commerce Subcommittee on Oversight and Investigations hearing called the 'Review of CDC Anthrax Lab Incident' on Capitol Hill in Washington July 16, 2014.
U.S. lawmakers on Wednesday faulted a "dangerous pattern" of safety lapses at government laboratories handling deadly pathogens such as anthrax and avian flu, calling for an overhaul of controls at the Centers for Disease Control and Prevention.
Members of a House Energy and Commerce Committee subcommittee cited new information on breaches previously unreported by CDC, which is under scrutiny for the potential exposure of more than 80 lab workers to live anthrax bacteria in June. No one has fallen sick due to the lapses.
