Results of a study of sporotrichosis in humans indicate that forestry workers accounted for 17%, gardeners and florists for 10%, and other occupations associated with soil (such as farmers) for 16% of all infections with S schenckii. Human infections with S schenckii have occurred primarily after handling plant material; in 1983, for example, 12 cases of cutaneous sporotrichosis were reported among hay-mulching workers in Oklahoma and New Mexico.3 The most extensive outbreak of horticulture-related sporotrichosis occurred in 1988, in which 84 workers acquired cutaneous sporotrichosis after handling conifer seedlings that were packed in Pennsylvania with sphagnum moss that had been harvested in Wisconsin.4,5 In that outbreak, people in 15 states were affected, including forestry workers, garden-club members, and nursery workers. Sphagnum moss was also identified by investigators with the Centers for Disease Control and Prevention as the source of sporotrichosis in 10 horticultural workers in a Disney World topiary.6
