Evaluation of Methods for Controlling and Monitoring Occupational Exposure of Workers in Swine Facilities
Reduction of personal exposure to air contaminant levels including ammonia and dust in swine production facilities is possible through containment control studies but must be studied under swine barn conditions too. Selected management and engineering measures were studied, such as high level of cleaning, oil sprinkling, low protein diet and manure pH manipulation to see how they impacted ammonia and respirable dust concentration levels in a swine production room. Ammonia concentrations could be reduced through pH manipulation of manure, low-protein diet and employing a high level of cleanliness. Spraying canola oil reduced dust levels. Average daily gain was similar in all conditions.
