✦ Synopsis
Dust concentrations were reduced by 35 -60% in pig buildings , while human dust exposure was lowered by 50 -70% by adding 4% animal fat to the feed . However , there is still a large quantity of airborne dust in these buildings and workers should reduce their exposure risk to the high concentrations by wearing a dust mask . Variations exist in dust concentrations for total dust in pig buildings . The respirable dust fraction does not appear to be location-dependent and therefore may be a better indicator for evaluating dust reduction methods . Further studies are needed to find the nature of these variations in total dust concentration , so that a representative measurement can be determined for a pig building . Total dust levels found
