MADISON, Wis. -- The University of Wisconsin-Madison will stop making its signature aerosol chambers used for researching infectious disease.
Those chambers have been involved in a few dangerous lab accidents nationwide.
An internal audit found the program was poorly managed and carried the potential for huge liability costs.
The auditor's report was obtained by The Associated Press under the open records law.
For years the university made so-called Madison chambers after they were pioneered in one of its labs in the 1970s.
The chambers are used to infect research animals.
David McMurray at Texas A&M has used chambers in his tuberculosis research.
McMurray says the only privately-manufactured alternative is much less efficient and safe.
McMurray is planning to organize researchers who use them to lobby the federal government to take over production.
