A case report was offered of a patient with occupational asthma following exposure in a beet sugar processing mill. The patient was a 33 year old white male. He had experienced shortness of breath, dry cough, sharp chest pains, sore throat, headache, fatigue, stiffness in the joints and difficulty sleeping during the summer of 1985. His symptoms finally cleared after he left his job. He had begun working at the sugar beet processing facility in 1973, and worked only during the processing season until 1985. He started working full time during 1985. His symptoms always abated during periods in which he was absent from the job. He demonstrated positive methacholine testing, positive skin tests with moldy beet sugar pulp, positive immunoglobulin-G (IgG) titer for Aspergillus- niger, and positive bronchoprovocation testing to moldy but not fresh beet sugar pulp. He had no evidence of bagassosis. His roentgenogram was repeatedly normal and there was no documentation of rales or decreased forced vital capacity either in the medical record or after bronchoprovocation challenge. He tested negative for specific IgG to Thermoactinomyces-sacchari.
