After Possible Leak in Ga., Minn. Bio Lab 'Absolutely' Safe

Minnesota's only public health bio-safety lab is "absolutely very secure," even after the same type of lab at the Centers for Disease Control in Atlanta is under investigation for claims of "major violations" of safety.

"We have not had a breach at this lab," Maureen Sullivan, supervisor of the Public Health Prepardness Unit at the Minnesota Department of Health, told 5 EYEWITNESS NEWS.

During a tour of the "level three" lab at an undisclosed location in the metro, Sullivan explained that her staff tests some of the most dangerous infectious diseases known to man.

"We deal with things like tuberculosis, rabies, anthrax, plague," said Sullivan.

On Monday, ABC News and USA Today reported about possible "major violations" at a Level three bio-safety lab in Atlanta. Internal emails, obtained by the news outlets, reportedly show air from a secure area at a bioterror germ lab leaked into a supposedly clean zone. Some people were concerned about exposure to that contaminated air, the reports said.
