Pesticide residue standard

Among the current effective standards for pesticide residues in China, one item of national standard stipulates 477 residue limits, and 140 items of the Agricultural Banking Code stipulate 162 residue limits. A total of 172 pesticides. Among them, in 2004 the Ministry of Agriculture issued three agricultural residue standards. Because it is a standard, it does not cause much concern. However, this is the first time that the Ministry of Agriculture of the People's Republic of China has issued the Agricultural Remnant Standard, which is also the first time since China's accession to the WTO to issue a pesticide residue standard, which is still of great significance to China's pesticide residue standards. The three criteria are: (1) NY 773-2004 "Maximum Residue Limits for Acetamiprid in Fruits". This standard only stipulates the residue limit of a pesticide in the locust insecticide in fruits. (2) NY 774-2004 "Resistance Limits of 13 Kinds of Pesticides such as Cypermethrin in Leafy Vegetables" This standard specifies the residual limits of 13 pesticides such as cypermethrin in leafy vegetables. (3) NY 775-2004 "Residue Limits of 11 Kinds of Pesticides such as Diniconazole in Maize". This standard specifies the residue limits of 11 pesticides such as diniconazole in corn.

In January 2005, China's GB 2763-2005 "Maximum Residue Limits of Pesticides in Food" standard was finally released. This standard integrates and revise the country's national standards for pesticide residues that have been issued in China. It replaces the 34 national standards for pesticide residue that have been issued in China and has completely changed the scattered national pesticide residues in China. The standard has 136 pesticides, an increase of 57 pesticides, an increase of 41.9%, compared with the original pesticide residues, and a limit of 477 residues, an increase of 59.1%. The inadequacies of this standard are: (1) The standards and method standards for limited quantities are still not matched. According to statistics, there are acifluorfen, alachlor, diureticum, bensulfuron-methyl, chlormequat, tetrabenzidine, cyromazine, diphenylamine, diquat, endosulfan, ethephon, chloropyrimidine. There are no detection methods for 20 pesticides such as alcohol, benzoxazole, fluoxyloacetic acid, flusilazole, tetrachlorophenyl hydrazine, glyphosate, imazalil, mediamine, and tebuconazole. Because there are more than one method standards, the specified methods are not given in the standard, which causes the diversity of detection methods. Different detection methods often lead to differences in test results, which affects the determination of test results and causes some unnecessary troubles. (2) Standards 4.100.5 and 4.101.5 stipulate that parathion and methyl parathion "must not use such pesticides in such foods. This value is the measurement limit of the test method." This method does not Doing science, because the detection limit of the method is a dynamic value. For the same test object, different methods have different detection limits, and the same detection method will change with the detection limit. Therefore, the banned pesticide should be set to 0.01 according to international practice.

In 2007, the Ministry of Agriculture issued 98 items of the “Maximum Residue Limits of Agricultural Products Pesticides”; in 2008, the Ministry of Agriculture again issued 39 items of the “Maximum Residue Limits of Agricultural Products Pesticides”. Industry standards set limits on the use of pesticides that are restricted in use, effectively raising the level of China's pesticide residue standards. This is more in line with the actual situation of pesticide use in China and can more effectively regulate the quality and safety of agricultural products in China. For example, in 2008, the Ministry of Agriculture issued the maximum residue limits for 20 pesticides such as methamidophos in vegetables and fruits. These standards are all the residue limits for highly toxic and high residue pesticides that are banned and restricted on vegetables and fruits in China. The formulation of residue limits for the ban on restricted pesticides is very much in line with the actual situation of pesticide use in China. Because the use of pesticides in China is very different from the registration of pesticides, although according to the requirements of pesticide registration in China, pesticides should not be used beyond the scope of registration. However, the use of pesticides beyond the scope of registration in China is very common, and the use of pesticides with restricted use is prohibited. Frequently, the ban on restricted pesticides is often a good control of pesticides, and the reason why pesticides are banned because of the high toxicity of these pesticide residues. Therefore, pesticides that are a real threat to the quality and safety of agricultural products in China are banned and restricted pesticides. The establishment of residue limits for the ban on restricted pesticides is the key.

The benchmarks have a good complementary effect to the national standard. For example, Article 4.72.4 of GB 2763-2005 only stipulates the limits of fluvalinate in cabbage vegetables and cottonseed oil, while NY 774-2004 has no effect on leafy vegetables. The limit of fluvalinate is specified; GB 2763-2005 does not specify the limits of carbofuran in fruits and vegetables, while NY 1500.40.1-2008 and NY 1500.40.2-2008 specify that Carbofuran is Limits in fruits and vegetables.

The inadequacy of agricultural residue standards is fragmented and fragmented. It is often a standard that sets a residue limit for only one or a type of agricultural product. That is, an indicator is a standard. According to statistics, the Agricultural Banking Standard issued 140 items in total for 3 times, and 138 criteria are all indicators of a standard; the 137 standards released in 2007 and 2008 with the “Maximum Residue Limits of Agricultural Products Pesticides” are all one standard. One indicator. This method, which is inconsistent with the international pesticide residue standards, is also not convenient to use, and it also leads to a waste of standard development resources.

In addition, there are conflicts between the indicators of agricultural residues and national standards. For example, Article 4.101.5 of GB 2763-2005 stipulates that methyl parathion shall not use such pesticides in such foods. This value is the test method. The limit of determination, which means that methyl parathion in the banned agricultural product residues limit, is the detection limit of the detection method, while NY 1500.40.1-2008 and NY 1500.40.2-2008 respectively stipulate methyl parathion in fruit Both vegetables and vegetables have a limit of 0.02 mg/kg, while methyl parathion is a banned pesticide on fruits and vegetables.
