Agricultural occupations are associated with a variety of soil-borne pathogens and diseases. Pathogen specific environmental conditions such as humidity, compost, animal manure, and decaying wood often produce geographically localized epidemiology. Soil-borne infections from occupational or vocational exposure usually occur through inoculation of the organism into the skin or by inhalation of the organism. Pathogens discussed in this chapter include bacterial and fungal agents directly or indirectly related to agricultural work in the soil itself (Table 28.1) (1,2).
