Farming is still one of the most important economic sectors in the world. At the same time, a high prevalence of respiratory diseases in farmers is well known. Among these, allergic and non-allergic asthma, chronic bronchitis, hypersensitivity pneumonitis and organic dust toxic syndrome (ODTS) are of uppermost importance. Because of the large variety of agriculture across Europe exposure conditions and risk factors for airway diseases may vary largely. While exposure to organic dusts and irritants are most important in grain and animal production, workers in greenhouses are mainly exposed to pollen, fungi, as well as pesticides. Up to now, the knowledge about the prevalence of respiratory diseases in European farmers working in different agricultural sectors was limited. Furthermore, reliable data on farming characteristics as well as exposure patterns that might prone risk factors for respiratory diseases were missing. Therefore, the European Farmers' Project was initiated. The results of this study are given in the second part of this paper.

“…Exposure to bioaerosols in intensive livestock buildings are intensively discussed as risks for animals' as well as workers' health (Cormier et al, 2000; Danuser, 2000; Douglas et al, 2018; Hall et al, 2020; Chmielowiec‐Korzeniowska et al, 2021; Tang et al 2021). Microorganisms (bacteria, archaea, fungi and viruses), plants, their biomolecules (lipids, DNA, Lipopolysaccharides (LPS, endotoxins) and proteins) and their spores and pollen have already been identified in bioaerosols, which inevitably leads to poor air quality in high concentrations (Fröhlich‐Nowoisky et al, 2016).…”

Bioaerosols in swine confinement buildings: A metaproteomic view

Swine confinement buildings represent workplaces with high biological air pollution. It is suspected that individual components of inhalable air are causatives of chronic respiratory disease that are regularly detected among workers. In order to understand the relationship between exposure and stress, it is necessary to study the components of bioaerosols in more detail. For this purpose, bioaerosols from pig barns were collected on quartz filters and analysed via a combinatorial approach of 16S rRNA amplicon sequencing and metaproteomics. The study reveals the presence of peptides from pigs, their feed and microorganisms. The proportion of fungal peptides detected is considered to be underrepresented compared to bacterial peptides. In addition, the metaproteomic workflow enabled functional predictions about the discovered peptides. Housekeeping proteins were found in particular, but also evidence for the presence of bacterial virulence factors (e.g., serralysin‐like metalloprotease) as well as plant (e.g., chitinase) and fungal allergens (e.g., alt a10). Metaproteomic analyses can thus be used to identify factors that may be relevant to the health of pig farmers. Accordingly, such studies could be used in the future to assess the adverse health potential of an occupationally relevant bioaerosol and help consider defined protective strategies for workers.

Bioaerosol emissions in a poultry litter burning plant

et al. 2009

This study investigates the exposure of workers to biological particles in a poultry litter burning plant in operation. The microorganism concentrations were examined at different workplaces during procedures leading to increased emissions. The concentrations of culturable airborne mesophilic, xerophilic and thermophilic microorganisms in the ambient air were tested inside and outside of the burning plant using two different methods of measuring. The focus of this study was on the quantitative evaluation of culturable bacteria as well as the quantitative and qualitative evaluation of gram-negative bacteria, fungi and thermophilic actinomycetes. The maximum airborne concentrations were found in the delivery hall. Mesophilic bacteria concentrations reached up to 1.7 9 10 6 CFU/m 3 ; gram-negative bacteria up to 9.1 9 10 2 CFU/m 3 . Fungal propagule concentrations for xerophilic fungi were between 1.2 9 10 3 and 2.9 9 10 4 CFU/m 3 and for mesophilic fungi between 4.4 9 10 2 and 2.9 9 10 4 CFU/m 3 . Among fungi, Aspergillus niger, Eurotium herbariorum and Scopulariopsis brevicaulis species were dominant. Thermophilic actinomycetes reached airborne concentrations of 8.7 9 10 4 CFU/m 3 , with increased concentrations of the pathogens causing extrinsic allergic alveolitis. The high concentrations of airborne microorganisms in poultry litter burning plants and the potential hazard of the intake of microorganisms including potential pathogens require the introduction of consistent measures in both technical areas and personnel management.
