Title Airways inflammation among workers in poultry houses
Bibliographic information June 2006, Vol.79, No.6, p.487-490. 26 ref.
Abstract This study evaluated the usefulness of airway responsiveness measurements to diagnose the presence of airways inflammation and relate this to occupational exposure among poultry workers. The group studied comprised 42 non-smoking poultry workers and 40 non-smoking controls unexposed to organic dusts. The presence of symptoms was evaluated using a standardized questionnaire for organic dust exposures. Airway responsiveness was measured using the methacholine challenge test. The concentrations of airborne endotoxin and (1-3)-β-D-glucan were measured. Exposure levels were in excess of those expected to cause effects in the airways. Compared to controls, exposed workers had significantly higher airway responsiveness and a higher prevalence of toxic pneumonitis, airways inflammation and chronic bronchitis. Endotoxin levels in the poultry buildings exceeded those suggested in earlier studies as the threshold value for airways inflammation.
