Farmers are known to be at high risk from the development of occupational airway disease. The first stage of the European farmers' study has shown that pig farmers in Denmark and Germany, poultry farmers in Switzerlad and greenhouse workers in Spain were at highest risk for work-related respiratory symptoms. Therefore, the aim of this study was to determine exposure levels at relevant farm workplaces. Dust and endotoxin levels as well as microbiological concentrations were determined in 213 crop and animal farming environments by personal sampling. The highest total dust concentrations were found in poultry houses in Switzerland with median concentrations of 7.01 mg/m**3. The median airborne endotoxin concentrations in total dust ranged between 0.36 ng/m**3 in Spanish greenhouses and 257.58 ng/m**3 in poultry houses in Switzerland. Likewise, the highest median concentrations of total (2.0 x 10**7 cells/m3) and active fungi (4.4 x 10**5 cfu/m**3) have been found in Swiss poultry houses. The predominant fungus taxa discovered in poultry houses were Eurotium spp. and thermophilic fungi. Cladosporium and Botrytis were mainly detecated in greenhouses. The exposure level found in this study might put the farmers at risk from respiratory diseases.

The aim of the European Farmers' Project was to determine prevalence and risk factors of respiratory diseases in farmers across Europe. A cross-sectional study in 7 centres was carried out. In the first stage of the study, nearly 8000 farmers in Denmark, Germany, Switzerland, the UK, and Spain answered a standardised questionnaire on farming characteristics and respiratory symptoms. The second stage of the study included exposure assessment and lung function measurements in 4 of the centres. Within the group of farmers, pig farmers were at high risk of asthma-like syndrome as compared to farmers keeping other kinds of animals. Among plant farmers, greenhouse workers were at higher risk for symptoms of asthma. The prevalence of symptoms of allergies were significantly lower among animal farmers as compared to the population of the European Community Respiratory Health Survey. In contrast, animal farmers had a signifcantly higher prevalence of symptoms of chronic bronchitis. The major risk factor for respiratory symptoms was shown to be ventilation of the animal houses and greenhouses. Intervention studies are now warranted to test the effectiveness of improved ventilation on respiratory health. The reasons for the low prevalence of allergic diseases among farmers are currently under study.
