The Centers for Disease Control sign is seen at its main facility in Atlanta, Georgia June 20, 2014. U.S. authorities increased to 84 people their count of government workers potentially exposed to live anthrax at three laboratories in Atlanta as they investigated a breach in safety procedures for handling the deadly pathogen. Researchers in the CDC's high-security Bioterror Rapid Response and Advanced Technology laboratory realized they had sent live anthrax bacteria, instead of what they thought were harmless samples, to fellow scientists in two lower-security labs at the agency.
