Title Evaluation of chronic respiratory effects in the potato processing industry: Indications of a healthy worker effect?
Bibliographic information Dec. 1998, Vol.55, No.12, p.883-827. 39 ref.
Abstract Self reported chronic respiratory symptoms and spirometric lung function were assessed in a cross sectional study among 135 potato processing workers. Evident relations between current exposure indices and respiratory health in the entire group were not found. Workers employed ≤5 years showed a two-fold higher prevalence of respiratory symptoms, lower lung function, and higher endotoxin exposure than workers employed for >5 years. Also, atopy was more prevalent in workers employed ≤5 years. After stratification for duration of employment, negative effects of endotoxin on lung function among workers employed ≤ 5 years were suggested. This study does not show chronic respiratory effects of exposure to organic dust in the potato processing industry. A likely explanation for not detecting apparent effects might be that many symptomatic workers drop out of this industry a few years after starting the job, suggesting a healthy worker effect.
