CDC scientists were studying the bacteria in a high-level biosecurity lab and then transferred the samples to three lower-security labs without first properly inactivating the live microbes. Workers in those labs handled the samples without using personal protective equipment, such as gloves. The procedural lapse happened between June 6 and June 13, and CDC spokesperson Thomas Skinner told The New York Times that while none of the researchers exposed to the bacteria are showing symptoms of infection, many of them are receiving prophylactic antibiotic treatment “out of an abundance of caution.”

CNN reported on Thursday afternoon that 54 CDC employees determined to have been in the labs or hallways at the time live anthrax was present have been seen by the agency’s Occupational Health Clinic. ...
