Production methods in animal farming have changed dramatically over the past 20 years. An emphasis on cheaper, more efficient ways of production has provided the impetus for larger, more concentrated systems. Improvements in building construction, heating and ventilation have been developed that provide the opportunity to increase the number of anima ls that can be raised in confinement. Improvements in animal health have reduced the risk of loss from disease. Confinement of large numbers of animals can have adverse effects on the environment and upon the health of employees exposed to such environments. As the trend toward large scale animal production continues, more workers will be employed full-time in this occupation, which increases the risk for disease and injury. The environment within livestock and poultry buildings contains many different respiratory hazards for the worker. These include gaseous contaminants such as ammonia and hydrogen sulfide, and particulate contaminants (dust), including animal dander, dried feces, endotoxin, molds and fungi.
