Screening of 725 pesticide residues in imported fruits in Beijing market

Abstract

ObjectiveTo provide a reference basis for the early warning of food safety risks and the formulation of trade policies on imported fruits in our country， the pesticide residues in imported fruits in Beijing was investigated.MethodsA total of 60 batches of fruit samples that label claims to be imported from 13 countries/regions such as Australia， the Philippines and so on were studied， and 725 pesticide residues were screened by GC/LC-Q-TOF/MS.ResultsAmong 60 batches of samples， 58 batches were qualified， and the qualified rate was 96.67%. Seventy-four kinds of pesticide residues were detected among 725 screening items， most of which were low-toxic， and the detection rates were 6.70% （25/373） for pyraclostrobin， 5.90% （22/373） for spirotetramat， 4.82% （18/373） for trifloxystrobin and 4.29% （16/373） for fluazolamide.ConclusionThe detection rate of pesticide residues in imported fruits in Beijing was good. The results indicate that the overall pesticide residues in imported fruits are at safe levels， but the potential health risks need to be concerned.
