The reporter learned today that in 2025, the General Administration of Market Regulation approved the publication of a total of 226 national standard substances in the field of food and agricultural product safety, providing accurate measurement support for pesticide and veterinary drug residue testing and further strengthening the safety line of food and agricultural products. The approved standard substance for anti-aphrovir solution in methanol and the standard substance for methanol-poisoned chlorpyrifos solution can be used to test pesticide residues in food and agricultural products. Due to its remarkable aphid control effect, chlorpyrifos is commonly used to kill pests on various crops. If the residue in food and agricultural products exceeds the standard, it may interfere with the normal function of the human nervous system, and long-term intake can also cause chronic health risks. The introduction of such standard substances can improve the comparability of pesticide residue test results in different laboratories.
