A report on lab safety at the U.S. Centers for Disease Control and Prevention put together by a committee of external experts calls the agency's commitment to safety inconsistent and insufficient." The report, which was completed in January but posted on the agency's website this week, also says "laboratory safety training is inadequate." An external group of 11 experts in biosafety, laboratory science and research [say] in the report [that] they are "very concerned that the CDC is on the way to losing credibility." The agency created the advisory group to improve lab safety in July in the wake of two mishaps and other issues that were uncovered. One incident occurred in June when dozens of employees in a bioterrorism lab working with the deadly anthrax virus, were at risk because of a failure to properly follow sterilization techniques. The head of that lab resigned after the incident. This followed a May incident in which avian influenza samples, thought to not be dangerous, were unintentionally mixed with the deadly H5N1 influenza virus and then shipped to a USDA lab. Then in December, with the advisory group already working to reduce lab safety risks and improve the culture of safety, employees in the Ebola lab were potentially exposed to that virus when a technician mistakenly transported the wrong specimens from a high-level lab to a lower-level lab. Internal investigations were done after each incident.
