Distribution of lost-work-time claims for skin disease in California agriculture: 1978-1983.

In order to identify California agricultural workers at high risk for occupational skin disease, we evaluated the distribution of 2,722 claims for lost-work-time skin conditions reported between 1978 and 1983 by Standard Industrial Classification (SIC) and source of illness. In the overall work force, cases were most frequently attributed to plants (52.1%), chemical exposures (20.4%), and food products (12.5%), but considerable variation occurred in the distribution of cases among the subdivisions of agriculture. The forestry subdivisions (SICs 081, 082, 084, and 085) had the highest rate (given as cases/10,000 employed) of claims for skin disease attributed to plants (53.5), but no cases due to other exposures. For chemical exposures, the highest rate of claims occurred in the horticultural specialities (SIC 018) subdivision (5.1), but this group also had a significant claims rate for plant-related skin disease (15.9). The highest claims rate for cases attributed to food products occurred in the vegetables/melons subdivision (4.7), but this group had claims rates for exposure to plants (3.8) and chemicals (2.8) that were nearly as high. Efforts to evaluate and prevent skin disease in agricultural workers should recognize the complex range of exposures to which this work force is subject.
