Title Respiratory illness in workers of an indoor shiitake mushroom farm
Bibliographic information Feb. 1993, Vol.8, No.2, 112-119. Illus. 49 ref.
Abstract An evaluation of an indoor shiitake mushroom farm was conducted following reports of respiratory illness symptoms among the workers. Predominant symptoms were dry cough, nasal discharge, sneezing, chest tightness, productive cough, and dyspnoea. Bioaerosol screening was conducted for mesophilic and thermophilic bacteria and fungal spores. Air concentrations of culturable fungal spores measured with the impactor exceeded 8.4 x 103 colony forming units/m3. The highest airborne fungal spore concentration measured was 2.4 x 106 spores/m3. Sampling results showed extensive airborne contamination with a variety of Penicillium species, which produce respirable-size spores that may function as potent allergens.
