• Description:
  This presentation covered the following objectives: Study 1: Task-based exposure assessment of inhalable dust during work in broiler chicken production; Determine personal exposure to inhalable dust. Study 2: Task modification - "dead bird pickup" during work in broiler chicken production; Compare exposures across "traditional" and "modified" task. Study 3: Exposure assessment during the composting of birds euthanized during an outbreak of avian influenza; Measure NH3 concentrations during composting of euthanized birds. Study 4: Evaluate the effectiveness of a water sprinkler system to reduce inhalable dust and ammonia concentrations in a broiler chicken house. This presentation had the following conclusions: Inhalable dust exposure concentrations were below OSHA regulatory limits, but above recommended limits; Duration of work task varies by farm size. Dust is predominantly composed of microbes; Additional bioaerosol control technology should be evaluated in poultry production. There is a statistical difference in microbial populations between aerosolized dust and settled dust. Lower variance in microbial populations among air samples. Workers are exposed to hazardous concentrations of NH3 during cleanup from AI events. Use of mechanical fan ventilation and liquid litter amendment reduced exposure; Future studies should evaluate methods to reduce generation of dust. [Description provided by NIOSH]
