The hearing, by the House Energy and Commerce Subcommittee on Oversight and Investigations, was prompted by an incident in June in which scores of CDC employees were potentially exposed to anthrax after a laboratory worker failed to adequately sterilize a sample of the deadly bacterium. A CDC review of the incident released last week found additional lapses, including the accidental transfer of a highly pathogenic strain of the H5N1 influenza, or “bird flu.”1

Tim Murphy, a Republican Representative for Pennsylvania who chaired the hearing, said that the anthrax incident and other newly disclosed safety lapses at CDC laboratories “raised serious questions about the CDC’s ability to safeguard properly select agents in its own labs.” Select agents are natural or manmade organisms or toxins that pose a severe threat to health.
