The National Institute for Occupational Safety and Health has expanded its research program investigating agricultural injuries. Data from the Supplementary Data System (SDS), maintained by the Bureau of Labor Statistics, U.S. Department of Labor, indicate that injuries to the back and lower extremities of agricultural workers are quite common. Injury data from SDS were examined for agricultural employees for the years 1985 through 1987 from the 21 states that consistently provided records for each year. During this 3-year period, a total of 71,098 injuries were reported to SDS for the agricultural Industry Groups included in this study. Of these, 26,450 (37.2%) were classified as sprains and strains. Analysis of the data indicate that workers in industries within the major groupings of crop production and agricultural services have an increased potential for sustaining a sprain or strain injury.
