The following notification of the Ministry of Public Health, No.387 (2017) [1], entitled “Food Containing Pesticide Residues”(Pesticide Residues in Food) provides a clear standard for food use and consumer safety. The “Maximum Residue Limit (MRL)” means the maximum concentration of a pesticide residue in food arising from the use of a pesticide. It is expressed in milligrams of pesticide residue per kilogram of food and “Pesticide Residue” means any specified substance in food resulting from the use of a pesticide. The term includes any derivatives of a pesticide, such as conversion products, metabolites, reaction products, and impurities considered to be of toxicological significance.

Ministry of Public Health Notification No.393 (2018) [2] amended Notification of the Ministry of Public Health No.387, by adding MRLs for four pesticides (carbosulfan, dithiocarbamates, imidacloprid and dinotefuran) in plants and animals. The amendment in the annex is as follows:
