Purpose. Farming is associated with a wide variety of hazardous exposures including physical, chemicals and biological agents. Animal farmers are exposed to dust, which contains microorganisms, mycotoxins, endotoxins, animal feed particles, allergens and chemical agents. Organic dust exposure is known to cause allergic and non-allergic rhinitis, and organic dust toxic syndrome. Measurements of serum cytokine levels have been performed as biomarkers and strong predictors of diseases in many epidemiologic studies. This study was undertaken to evaluate the relationship between occupational health hazards and serum pro-inflammatory cytokines among agricultural workers in north of Italy. Methods. A pilot study was conducted in 2010 and One hundred subjects working in agricultural enterprises in the region of Lombardy were enrolled into the study. Serum cytokines including interleukin IL-6, IL-8, IL-10, IFN gamma and tumor necrosis factor alpha were measured. Cytokines were assessed by commercially available enzyme-linked-immunosorbent assay (ELISA). Results of the study. Compared to control subjects, increased TNF-alpha, IL-8 and IL-10 levels were found in animal breeders, with a statistically significant relationship between type of job (breeder/non breeder workers) and increased serum pro-inflammatory cytokines.

Abstract

Purpose. Farming is associated with a wide variety of hazardous exposures including physical, chemicals and biological agents. Animal farmers are exposed to dust, which contains microorganisms, mycotoxins, endotoxins, animal feed particles, allergens and chemical agents. Organic dust exposure is known to cause allergic and non-allergic rhinitis, and organic dust toxic syndrome. Measurements of serum cytokine levels have been performed as biomarkers and strong predictors of diseases in many epidemiologic studies. This study was undertaken to evaluate the relationship between occupational health hazards and serum pro-inflammatory cytokines among agricultural workers in north of Italy. Methods. A pilot study was conducted in 2010 and One hundred subjects working in agricultural enterprises in the region of Lombardy were enrolled into the study. Serum cytokines including interleukin IL-6, IL-8, IL-10, IFN gamma and tumor necrosis factor alpha were measured. Cytokines were assessed by commercially available enzyme-linked-immunosorbent assay (ELISA). Results of the study. Compared to control subjects, increased TNF-alpha, IL-8 and IL-10 levels were found in animal breeders, with a statistically significant relationship between type of job (breeder/non breeder workers) and increased serum pro-inflammatory cytokines. Results suggest that animal breeders might be at higher risk of biological hazards than other farmers with less contact to animals. Blood cytokine assay may also be useful to identify individual responsiveness to endotoxins at work place. The relationship between exposure to organic dust, microorganisms, endotoxins and other chemicals in the work place and disease needs further research.
