Abstract

A number of recent reports have documented likely swine-to-human virus transmission in swine facilities. During the month of January 2016, weekly bioaerosol and pig oral secretion samplings were performed in a pig handling facility to assess the possible occupational exposure to swine influenza A virus and adenovirus. During the 4 weeks, a total of 35 specimens were collected from multiple pig pens within the animal facility. One bioaerosol sample and five pig oral secretion samples were found positive for porcine adenovirus and further sequencing data revealed two different porcine adenoviruses. None of the samples showed evidence for influenza A virus by molecular assays. While swine adenoviruses are not thought to infect man, their detections suggests that bioaerosol sampling may be a non-invasive approach to detecting emergent zoonotic pathogens in agricultural industries.
