Certain environmental conditions in animal and plant production have been associated with
increased frequency in respiratory illnesses, including asthma, chronic bronchitis, and hypersensitivity
pneumonitis, in farmers occupationally exposed in swine production. The aim of
this study was to characterize particulate matter (PM) contamination in seven Portuguese
swine farms and determine the existence of clinical symptoms associated with asthma and
other allergy diseases, utilizing the European Community Respiratory Health Survey questionnaire.
Environmental assessments were performed with portable direct-reading equipment,
and PM contamination including five different sizes (PM0.5, PM1.0, PM2.5, PM5.0, PM10) was
determined. The distribution of particle size showed the same trend in all swine farms, with
high concentrations of particles with PM5 and PM10. Results from the questionnaire indicated
a trend such that subjects with diagnosis of asthma were exposed to higher concentrations
of PM with larger size (PM2.5, PM5, and PM10) while subjects with sneezing, runny nose, or
stuffy nose without a cold or flu were exposed to higher concentrations of PM with smaller
size (PM0.5 and PM1). Data indicate that inhalation of PM in swine farm workers is associated
with increased frequency of respiratory illnesses.
