Abstract:
In order to understand the status of Chinese maximum residue limits (MRLs) standard for the pesticides in litchi and longan, and ensure the development of national litchi and longan industry, the current status of the Chinese MRLs standard for pesticides in litchi and longan were analyzed in this article based on the “National food safety standard-maximum residue limits for pesticides in food” (GB 2763-2021), combined with the registration of pesticides on the litchi and longan in China. The MRLs, Acceptable Daily Intake (ADI) and corresponding standards for detection methods are listed according to the types of pesticides. Statistics showed that there were 133 MRLs in 125 types of pesticides related to litchi and longan in GB 2763-2021, among which 109 recommended MRLs have corresponding detection methods, and 33 valid MRLs that have been registered in China. Comparing to GB 2763-2019, 53 MRLs standards were newly added and the growth rate was up to 66.25%. Moreover, 3 standards on detection methods were newly added. However, according to the data from the monitoring of pesticide residues, standards on MRLs and detaction methods for litchi and longan still need to be supplemented, and the process for setting up standards on the MRLs and detection methods for litchi and longan needs to be speeded up.
