An outbreak of chlamydiosis was investigated in workers at a duck farm and processing plant during winter 1989. Chlamydia psittaci was isolated from ducks, but there was little evidence of clinical chlamydiosis in the ducks. Serological tests showed that 76 percent of the workers had been exposed to infection, 12 percent recently, 16 percent had not been exposed and 8 percent had inconclusive test results. There was a strong association between years of employment and exposure to infection. Infection appeared to be contracted during the first year of employment. Measures were implemented to reduce shed contamination and control rodents and wild birds. At the same time, ducks were medicated, the processing plant was modified, work practices were altered and workers were advised about chlamydiosis to reduce the risk of human infection.
