The respiratory health of Victorian broiler growers

Chicken meat farmers in Victoria were surveyed for respiratory symptoms and lung function; 77% denied any respiratory symptoms, while almost 12% had chronic bronchitis. This prevalence is similar to that in some other dusty industries. After adjusting for other factors increased prevalences of cough and/or sputum, chronic bronchitis and wheeze were found for smokers, those with a family history of atopy, and those with greater cumulative time spent inside chicken sheds. The use of respiratory protective equipment was not associated with fewer symptoms, possibly because farmers only used it after they had become affected. The results of spirometry correlated with symptoms but were not related to cumulative time spent inside chicken sheds. Chicken farming is not without its occupational respiratory problems and people with atopy may be at increased risk in this industry.
