Safety concerns at a prominent military germ lab have led the government to shut down research involving dangerous microbes like the Ebola virus.

“Research is currently on hold,” the United States Army Medical Research Institute of Infectious Diseases, in Fort Detrick, Md., said in a statement on Friday. The shutdown is likely to last months, Caree Vander Linden, a spokeswoman, said in an interview.

The statement said the Centers for Disease Control and Prevention decided to issue a “cease and desist order” last month to halt the research at Fort Detrick because the center did not have “sufficient systems in place to decontaminate wastewater” from its highest-security labs.

But there has been no threat to public health, no injuries to employees and no leaks of dangerous material outside the laboratory, Ms. Vander Linden said.
