The Southeast Center collaborates with several other NIOSH funded Agricultural Safety and Health Centers (CS-CASH and Northeast Center) on surveillance projects that involve mining a variety of data sources to document the types, situations and numbers of incidents of agricultural injury and fatality. Accurate statistics are often difficult to ascertain as agricultural injuries and fatalities are often not reported as such or are embedded in other occupational injury or fatality categories. For example, a collision between a tractor and motor vehicle on a rural roadway may be reported only as a traffic accident or a hospital emergency room report of a traumatic brain injury (TBI) resulting from a fall from a horse may not include the precipitating incident context.
