In response to a request from the Florida Department of Health and Rehabilitative Services, an investigation was begun regarding occupational transmission of tuberculosis among state employees in laboratories where clinical specimens were processed. The Florida Health and Rehabilitative Services laboratories (SIC-8071) in Miami, Jacksonville and West Palm Beach were examined; there were 95 employees at the three sites. Of these, 39 met the criteria for participation in the evaluation of tuberculin skin test conversion rates. Documented conversions were noted in nine persons between March 1989 and September 1992. Ventilation systems were evaluated at two of the three laboratories. The authors conclude that workers performing laboratory and clerical work with viable Mycobacterium- tuberculosis specimens may be at increased risk of becoming infected. However, the limitations of this study make it difficult to draw any definitive conclusions regarding the risk of occupational transmission of tuberculosis at these laboratories. The authors recommend specific measures to reduce the risk and improve the working environment.
