Group 1 - The State Administration for Market Regulation approved a total of 226 national standard substances in the field of food and agricultural product safety by 2025, enhancing the precision of pesticide and veterinary drug residue testing [1] - The approved standard substances for pesticide residue detection include methanol solutions of acetamiprid and chlorpyrifos, which are widely used in agriculture and pose health risks if residues exceed safe levels [1] - The approved standard substances for herbicide residue detection include acetone solutions of propanil and trifloxysulfuron, which are commonly used in rice and soybean cultivation, respectively, and their excessive residues can harm subsequent crops and human health [1] Group 2 - The approved standard substances for veterinary drug residue detection include methanol solutions of ofloxacin and acetonitrile solutions of malachite green, which have been associated with antibiotic resistance and potential carcinogenic risks, respectively [2] - The use of these standard substances will provide precise testing bases for veterinary drug residues in livestock and aquatic products, ensuring food safety [2]

Core Viewpoint - The National Market Supervision Administration plans to approve and release a total of 226 national standard substances in the field of food and agricultural product safety by 2025, enhancing the precision of pesticide and veterinary drug residue testing and strengthening the safety defense of food and agricultural products [1] Group 1: Standard Substances - Standard substances are essential "scales" and "weights" for conducting chemical and biological testing activities, serving as a key element in national metrology capacity building [1] - The introduction of standard substances for pesticide residue testing, such as methanol solutions of acetamiprid and chlorpyrifos, will improve the comparability and reliability of pesticide residue testing results across different laboratories [1] - For herbicide residue testing, the use of acetone solutions of pendimethalin and trifloxysulfuron will enhance the precision of the residue testing process, providing strong support for quality control of food and agricultural products [1] Group 2: Veterinary Drug Residue Testing - The implementation of standard substances like methanol solutions of ofloxacin and acetonitrile solutions of malachite green will provide precise evidence for the detection of veterinary drug residues in livestock and aquatic products [1]

Core Viewpoint - The National Market Supervision Administration has approved a total of 226 national standards for food and agricultural product safety by 2025, enhancing the precision of pesticide and veterinary drug residue testing, thereby strengthening the safety measures for food and agricultural products [1] Group 1: Standards and Testing - The approved standard substances are essential for conducting chemical and biological testing, serving as critical elements in national metrology capacity building [1] - The introduction of standard substances for pesticide residue testing, such as methanol solutions of acetamiprid and chlorpyrifos, will improve the comparability and reliability of test results across different laboratories [1] - For herbicide residue testing, the use of acetone solutions of paraquat and trifloxysulfuron will enhance the precision of the testing process, providing strong support for quality control of food and agricultural products [1] Group 2: Veterinary Drug Residue Testing - The implementation of standard substances like methanol solutions of ofloxacin and acetonitrile solutions of malachite green will provide accurate bases for testing veterinary drug residues in livestock and aquatic products [1]
