| Abstract: | The relationship between air quality--its dust content--and respiratory diseases of animals in the food industry and otherwise is examined. The correlation between dust content and incidence of disease in farm animals is also discussed. Lesions caused either directly or indirectly by dust-transported microorganisms are reviewed. Effects of dust on animal performance are included. This review is an attempt to compile available information on the natural occurrence of stable dust and the possibilities for its measurement and control. |
