Abstract Using GC-MS/MS and LC-MS/MS methods，this paper tested 179 kinds of pesticide residues in 18 celery samples．Considering the LD50，ADI，proportion of celery intake to total diet，frequency of pesticide use，presence of high exposure population and median value of detection，this study applied the comprehensive safety assessment（FSA）method to calculate the total risk scores of different pesticide residues by 3 ways of evaluation，and then ranked them．The results showed that the safety risks of terbuthion，isocarbophos，quinalphos and difenofos in celery were relatively higher．At the same time，the advantages and disadvantages of FSA were also analyzed．
