Title Lung function and work-related exposure in pig farmers with respiratory symptoms
Bibliographic information Aug. 2000, Vol.42, No.8, p.814-820. Illus. 22 ref.
Abstract To evaluate characteristics of pigsties associated with the development of respiratory morbidity among 100 pig farmers with work-related respiratory symptoms, a standardized questionnaire was used, and lung function assessed immediately before and after pigs feeding. Exposure to dust and endotoxins was determined by personal sampling. Among these farmers, baseline lung function results were shown to be negatively associated with duration of employment, number of pigs on the farm, manual feeding and ventilation. The decrease in forced vital capacity and forced expiratory volume in 1 second over the feeding period was negatively correlated with air velocity, whereas respirable dust concentrations were shown to be significant predictors of maximal midexpiratory flow (MMEF25/75) decline. In conclusion, among symptomatic pig farmers, those with higher numbers of pigs and longer duration of employment are at highest risk for developing functional impairment.
