This report describes one approach to establish a surveillance method of farm injuries. The surveillance system is designed to be used to evaluate ongoing prevention activities related to education, training, and equipment design. To define the subset of information to be included in a surveillance system, existing data were analyzed. The mortality data were death certificates and the morbidity data were from the Farm Accident Survey conducted in 1978, (National Safety Council forms and sampling design). Limitations of the data currently available are discussed; information needs for an agricultural injury surveillance system are presented.
