Answers to Agricultural Health Case Study

1. Debbie’s condition is most likely (d), organic dust toxic syndrome. Our research has indicated 33% of swine producers have had one or more of these episodes. It occurs when there is a particularly heavy dust exposure, for example when moving and sorting hogs, or power washing buildings.

2. A good history (d), is the best answer, but a pulmonary function test (a) at the time of the episode should show a mild obstruction. (e) BAL at the time of the episode should show increased cells, primarily neutrophils.

3. High levels of endotoxin exposure (e),is the likely cause of her condition.

4. Continued exposure will most likely cause (b) increasing frequency of symptoms with less exposure. No other particular chronic problem is known, with the exception of possible bronchitis.

5. These episodes and others are best prevented by a combination of environmental control and personal protection (d).
