Bacteria load a surrogate to assess occupational exposure to bioaerossols?

In feed production, pug farms and swine slaughterhouses, the workers are exposure to bioaerosols. The aim of this study, was to asses occupational exposure to bacterial load (air and surfaces) in one feed production industry, in two pig farms and in one swine slaughterhouse. In addition, the authors intended also to analize the results together with the air fungal load already reported. Air samples were collected through an impcation method, while surface samples were collected by the swabbing method. The pig farms demonstrated to be the setting with the highest bacterial load. Bacterial load should not be a surragte to assess accupational exposure to bioaerosols, since bacterial and fungal load didn't present the same load trend, mainly in the feed industry and in clean and dirty slaughterhouse.
