The main purpose of this study was to investigate the respiratory effects of exposure to high atmospheric concentrations of flour dust. Methods This study was carried out in a local flour producing factory in Shiraz, in 1384. Sixty seven subjects (35 exposed and 32 non-exposed) were investigated. The prevalence of respiratory symptom as well as lung function capacities was evaluated. Additionally, atmospheric concentrations of flour dust were measured. The data were analyzed by Independent sample ttest, Chi-square or fisher's exact test and multiple linear regression.  Results   Atmospheric concentrations of dust exceeded current permissible levels. Additionally, exposed workers had higher prevalence rates of regular cough, productive cough, wheezing,  phlegm and shortness of breath. Likewise, significant (p M3 ER -
