Citing an anthrax scare and a recurring problem with safety, the Centers for Disease Control and Prevention on Friday shut down two research labs and stopped shipping highly dangerous germs to other labs, according to Reuters.
One of the closed facilities was involved an incident last month that could have accidentally exposed workers in three labs to anthrax. A second, previously undisclosed problem earlier this year involved deadly bird flu, Reuters reported.
The two lab safety problems were discussed Friday by CDC Director Dr. Tom Frieden, as well as a report that detailed three other incidents in the past decade in which mistakes or other problems caused potentially dangerous germs to be sent out, according to Reuters.
No lab worker or member of the public was sickened in any of the incidents, the CDC said, but Frieden acknowledged the CDC is entrusted to operate some of the world's most advanced and most secure laboratories for the handling of deadly germs, Reuters reported.
"I'm just astonished that this could have happened here," Frieden said, according to Reuters.
The disclosure comes days after the government revealed the discovery of six forgotten vials of smallpox virus in a laboratory building at the National Institutes of Health campus in Bethesda, Maryland, Reuters reported.
On Friday, Frieden announced that tests show that two of the 60-year-old vials had live virus. More testing is going on, but all the samples are to be destroyed. No infections have been reported in that incident, either, according to Reuters.
The CDC moratorium on shipment of highly dangerous germs will affect the federal agency's labs at its Atlanta headquarters and Fort Collins, Colorado, Reuters reported. The two Atlanta labs where the recent incidents occurred have been temporarily closed.
Frieden also announced that internal and external review panels will investigate both recent problems and review procedures, according to Reuters.
A CDC report on the anthrax incident found several errors and bad decisions, Reuters reported. The report said anthrax should not have been used in that lab experiment and the samples used weren't sterilized as expected.
In the flu incident, the CDC said a sample of an animal flu virus was accidentally contaminated with a deadly bird flu germ, according to Reuters. That sample was then sent to another government lab, which discovered the contamination in May, but wasn't reported to CDC's top management until this week, Frieden said.
