US health chief admits ‘pattern’ of safety failures
The chief of the US government's top public health agency on Wednesday admitted to a pattern of safety errors after dangerous mixups in the handling of influenza and anthrax. "I think we missed a critical pattern," said Tom Frieden, who leads the Centers for Disease Control and Prevention, during two hours of questioning from the House Energy and Commerce Subcommittee on Oversight and Investigations. Last week, the CDC admitted to five incidents over the past decade — two of them in recent months — in which workers shipped anthrax, flu, botulism and a bacteria known as brucella to other labs without following proper de-activation and safety procedures. No one was believed to have been hurt by the mishaps, but they exposed a major lapse of protocol within the CDC, which is viewed globally as a leading scientific and health agency.
