Technical Assistance Report No. TA-78-68, School of Veterinary Medicine, Tuskegee Institute, Tuskegee, Alabama.

The ventilation system was inspected and types of fungal growth were identified at the School of Veterinary Medicine, Tuskegee Institute (SIC-8221), Tuskegee, Alabama, on October 5 and 6, 1978, to determine health problems related to a widespread fungal contamination in about 75 offices and classrooms. The evaluation was requested by the state health department on behalf of 40 to 50 affected employees and 175 students. The fungi were identified primarily as Aspergillus, Penicillium and Cladosporium. Major factors responsible for rapid fungi growth were sustained high humidity, dirty filters, and a recirculation system that allowed airborne spores to circulate to all areas serviced by the common return air plenum between the false ceiling and attic floor. Other factors contributing to the abundance of spores were construction work, a flood, a collection of books involved in an earlier flood, roof leaks, water standing in condensate pans of air handling units, and insufficient chilling of the water entering the air handling units. The investigators conclude that fungal exposure is a health hazard in areas where concentrations are very high or for persons with immunologic defects. They recommend elimination and control of the abnormal fungal growth and decontamination of affected areas.
