Hundreds of bioterror lab mishaps cloaked in secrecy/ USA Today, 2014

From  USA Today, August 17, 2014:

More than 1,100 laboratory incidents involving bacteria, viruses and toxins that pose significant or bioterror risks to people and agriculture were reported to federal regulators during 2008 through 2012, government reports obtained by USA TODAY show.

More than half these incidents were serious enough that lab workers received medical evaluations or treatment, according to the reports. In five incidents, investigations confirmed that laboratory workers had been infected or sickened; all recovered...

But the names of the labs that had mishaps or made mistakes, as well as most information about all of the incidents, must be kept secret because of federal bioterrorism laws, according to the U.S. Department of Agriculture, which regulates the labs and co-authored the annual lab incident reports with the Centers for Disease Control and Prevention...

The new lab incident data indicate mishaps occur regularly at the more than 1,000 labs operated by 324 government, university and private organizations across the country that are registered with the Federal Select Agent Program. The program is jointly run by the USDA and the CDC, which are required by law to annually submit short reports with incident data to Congress...

"More than 200 incidents of loss or release of bioweapons agents from U.S. laboratories are reported each year. This works out to more than four per week," said Richard Ebright, a biosafety expert at Rutgers university in New Jersey, who testified before Congress last month at a hearing about CDC's lab mistakes.

The only thing unusual about the CDC's recent anthrax and bird flu lab incidents, Ebright said, is that the public found out about them. "The 2014 CDC anthrax event became known to the public only because the number of persons requiring medical evaluation was too high to conceal," he said.

Gigi Gronvall (of the UPMC-JHU biodefense center) notes that even with redundant systems in high-security labs, there have been lab incidents resulting in the spread of disease to people and animals outside the labs.

She said a lab accident is considered by many scientists to be the most likely source of the re-emergence in 1977 of an H1N1 flu strain that had disappeared in 1957 because the genetic makeup of the strain hadn't changed as it should have over those decades. A 2009 article in the New England Journal of Medicine noted the 1977 strain was so similar to the one that disappeared that it suggests it had been "preserved" and that the re-emergence was "probably an accidental release from a laboratory source." ...
