The agency released the report Tuesday. It was published in the January issue of Applied Biosafety.
The report is the CDC’s first analysis of reporting requirements implemented after the deadly 2001 anthrax attacks to track incidents of lost, stolen or released pathogens.
None of the infected lab workers died. The agency says the infection rate was far lower than the rate of general occupational illnesses in scientific research and development facilities.
The CDC says no thefts were reported. It says there was one incident in which a shipment of the fungus responsible for potentially deadly Rift Valley fever was destroyed by a shipping company.
