Abstract: Standards of maximum residue limits(MRLs) for pesticides are the key bases of food safety identification. Safety trap analysis of pesticide residue standards has very important value for avoiding the risk on food safety. This paper, by taking national standard Maximum Residue Limits for Pesticides in Food (GB 2763—2005) as a example, calculated the theory daily intake (TDI) of 439 residue indexes of 126 pesticides in foods and the correlation between MRLs, ADI(acceptable daily in take) and TDI, and then compared with the customer s Real Daily Intake (RDI). Among foods with 35 residue indexes, there were TDI values higher than their corresponding RDI values for different proportion customers, accounting for 7.3% of 478 pesticide residue indexes list in this national standard. It was concluded that this standard had a big safety risk trap and the government should revise this standard as soon as possible in order to eliminate the management trap on food safety.

Key words: pesticide residue, national standards, food safety trap
