AbstractIn a survey of chronic respiratory symptoms and airflow obstruction of a rural population aged 20–65 years, the effects of both farming and, in particular, the exposure to grain dust on the respiratory health of the people was examined. Of the 1,892 subjects (82% of the eligible population) studied, 924 were males and 968 females, with half living in the town. Three groups were identified: current, former, and never farmers. Almost all current farmers were exposed to grain for, on average, 2 months a year. There was no difference in atopic status between the groups. While there was a strong association between most symptoms and smoking, there was no association between symptoms and exposure to grain and farming category once age and smoking had been taken into account. Results of this study suggest that farmers do not have chronic respiratory symptoms or impairment of lung function because of their exposure to grain dust. Lung function of former farmers might have been affected by farming, and this may reflect more involvement with livestock in the pas
