Agricultural occupational fatalities in Pennsylvania for the years 1985-87 were followed up. Supplemental data concerning the occupation of the deceased and circumstances of the fatal accident were obtained from a family member. The number of fatalities designated as agriculturally and occupationally related by the National Traumatic Occupational Fatality (NTOF) system was compared with the number of fatalities identified by using alternative criteria for classification of agriculturally and occupationally related fatalities. There may be nearly a 30 percent error in the NTOF method resulting in a 20 percent undercount.
对宾夕法尼亚州1985 - 1987年的农业职业死亡情况进行了随访。从一名家庭成员那里获取了关于死者职业和致命事故情况的补充数据。将国家创伤职业死亡（NTOF）系统认定为与农业和职业相关的死亡人数，与使用农业和职业相关死亡分类替代标准确定的死亡人数进行了比较。NTOF方法可能存在近30%的误差，导致少统计20%。
