Title Respiratory health status in swine producers relates to endotoxin exposure in the presence of low dust levels
Bibliographic information Jan. 1994, Vol.36, No.1, p.49-56. Illus. 31 ref.
Abstract The respiratory health status of 54 male swine producers was assessed through questionnaires and spirographic measurements. The producers were between 25 and 48 years old and had worked an average 10.7 years in the industry, with an average of 4.7 h/day in the swine barns. Atmospheric contaminants were measured including carbon dioxide, ammonia, total dust, respirable dust, and airborne endotoxin. Endotoxin related to forced vital capacity and endotoxin times h/day was related to forced vital capacity and to forced respiratory volume in 1 second. Respiratory symptoms and lung function did not relate to categories of low, medium and high exposure to respirable dust. However, categories of endotoxin exposure related to respiratory symptoms. Thus, respiratory health status relates to endotoxin level but not to dust level at low dust levels. Control measures should aim to reduce the levels of endotoxins as well as those of dust.
