Respiratory disease among swine confinement (SIC-0279) workers is reviewed. Components of confinement systems include enclosed structures that accommodate many animals in a relatively small space; ventilation systems for control of the internal environment; systems for watering and feeding livestock; and systems for handling animal wastes. Implications for occupational health are considered. A research plan is presented to define and characterize the clinical response of workers, to characterize gas and particulate exposure, to investigate mechanisms to control exposures in the work environment, and to perform animal studies to predict potential chronic pathological effects on the human respiratory tract. A health hazard recognition study shows potential respiratory hazards to farmers and agricultural workers. Case studies of acute toxic exposures to hydrogen-sulfide (7783064) in swine confinement operations, potential hazards of carbon-monoxide (630080) to female confinement workers, and the use of swine as monitors of carbon- monoxide in the work environment are examined. A case control study of chronic respiratory disease in workers and the effects of environmental challenges on pulmonary function tests are presented. Studies of chronic respiratory hazards in rabbits and guinea-pigs are also cited. Environmental evaluations are reported for air measurement and analysis for gases and particulates inside swine confinement buildings.
