A letter report issued by the Government Accountability Office with an abstract that begins "As the number of biological labs increases, so too do the safety risks for lab workers. Data on these risks--collected through a safety reporting system (SRS) from reports of hazards, incidents, and accidents--can support safety efforts. However, no such system exists for all biological labs, and a limited system--managed by the Centers for Disease Control and Prevention (CDC) and the Animal and Plant Health Inspection Service (APHIS)--applies to only a subset of these labs. While a national SRS has been proposed, design and implementation are complex. In this context, GAO was asked to identify lessons from (1) the literature and (2) case studies; and to apply those lessons to (3) assess CDC and APHIS's theft, loss, or release (TLR) system for select agents, such as anthrax, and (4) suggest design and implementation considerations for a labwide SRS. To do its work, GAO analyzed SRS literature; conducted case studies of SRSs in aviation, commercial nuclear, and health care industries; and interviewed agency officials and biosafety specialists."
