Objective: To find out and compare the professionals proficiency of monitoring and inspection agencies on pesticide residue in food, and identify the main factors affecting the quality of result to provide references for improving the quality of the monitoring and inspection results.
Methods: Compare the national quality control examination results of pesticides residues in food of 2009 with 2011.
Results: The submission rates of examination results in 2011 were much higher than in 2009. They were respectively 100% and 83.6%. With the exception of few pesticides, the qualitative qualification rate and quantitative satisfaction rate of other pesticides were also relatively higher, and the qualitative qualification rate and quantitative satisfaction rate in 2011 were all higher than the same examination pesticides in 2009. For instance, the qualitative qualification rate of chlorpyrifos were respectively 99.4% and 96.8% in 2011 and 2009. The qualitative qualification rate of triazophos were respectively 100% and 97.1% in 2011 and 2009. The quantitative satisfaction rate of chlorpyrifos were respectively 93.8% and 90.2% in 2011 and 2009. The quantitative satisfaction rate of triazophos were respectively 91.9% and 87.2% in 2011 and 2009.
Conclusion: The general testing levels of monitoring and inspection agencies on pesticide residue in food were sufficient, and their testing proficiency increased year by year, but some institutions still need to improve the testing proficiency.
