Abstract | Concentrations and emissions of airborne endotoxins and microorganisms within and from 160 piggery buildings were surveyed in four states of Australia. Respirable dust samples collected on filter papers in the buildings were used to determine endotoxin concentrations. The total airborne microorganisms were measured using six-stage Andersen sampler. A refereed methodology was used to predict the emission rates from all buildings studied. An overall mean microorganism emission rate of 1.6 × 107 cfu/h/pig and a mean internal building concentration of 1.17 × 105 cfu/m3 were measured in the piggery buildings. An overall mean emission rate of 3.31 × 103 EU/h/pig and a mean internal concentration of 33.1 Endotoxin Units (EU)Zm3 were measured for respirable endotoxins. The lowest endotoxin concentrations were measured in dry sow buildings (23.3 EU/m3), while measurements taken in straw based shelters had the highest concentrations (84.98 EU/m3). Straw based shelters also had the highest mean bacteria concentration (3.27 × 105 cfu/m 3) and emission rate (44.1 × 107 cfu/h/500 kg live weight). |
