Title Exposure to culturable microorganisms in paper mills and presence of symptoms associated with infections
Bibliographic information June 2002, Vol.41, No.6, p.498-505. 32 ref.
Abstract Based on an exposure assessment, workers exposed to culturable bio-aerosols in 11 paper mills were divided into three exposure groups. 781 exposed and 285 unexposed workers completed a questionnaire that provided data pertaining to infections and associated symptoms. Concentrations of culturable bacteria in process waters varied in the range 104-106 colony-forming units (CFU)/mL, and in bio-aerosol concentrations varied typically in the range 104-105 CFU/m3. Operators exposed to bio-aerosols reported higher incidence of symptoms associated with infections compared to the reference population (odds ratio 1.7-5.9), and the group of highest exposed workers reported higher incidence than the lowest exposed group. It is concluded that exposure to bio-aerosols containing culturable microorganisms may induce symptoms associated with infections among operators in paper mills.
