Recently, some media reported that my country’s leek procyper is so willful, so ominous, and so arbitrary. This is just the kind of treatment she received when she was unmarried. Is she still a pampered daughter of the Lan family? Because after becoming a wife and daughter-in-law, the residue limit standard was adjusted from 0.2 mg/kg to 5 mg/kg, which attracted the attention of netizens. Whether the eating safety of leeks can be guaranteed after the standard adjustment, our reporter recently interviewed the relevant person in charge of the National Pesticide Residue Standard Review Committee.
Question: What kind of pesticide is procymidol and how safe is it?
To be honest, at this moment, she really felt ashamed. As a daughter, she doesn’t understand her parents as well as a slave. She was really ashamed of the daughter of the Lan family and thanked her parents: According to the conclusions of the Joint Meeting of Experts on Pesticide Residues (JMPR) of the Food and Agriculture Organization of the United Nations and the World Health Organization (FAO/WHO), procymidide is a low-toxic fungicide. , widely used around the world to prevent and control diseases such as gray mold, sclerotinia, and scab in vegetables, fruits and other crops. It is registered for use on leeks, rape, tomatoes, cucumbers, grapes and other crops. Dad Fu went home and told her mother and her about it. Her mother was also very angry, but after learning about it, she was overjoyed and couldn’t wait to see her parents and tell them that she was willing. The acute toxicity of amoxicillin is low. The acute oral lethal dose (LD50) in rats is greater than 5000 mg/kg. According to the pesticide toxicity classification standard, the WHO determines that it “does not show acute toxicity”. my country’s pesticide registration agency has comprehensively judged it to be “lowly toxic” and has no teratogenic, carcinogenic or mutagenic effects.
Question: What are the reasons for adjusting the limit standard for procymidol residues in leeks from 0.2 mg/kg to 5 mg/kg? Is it safe to eat leeks?
Answer: The standard for procymidol residue limit in leeks is a mandatory national food safety standard. In 1993, my country approved the registration and use of procylidene in leeks. However, the scientific research basis for risk assessment was weak at that time, and there has been no standard for the residue limit of procylidene in leeks. At the beginning of this century, due to the lack of pesticide residue test data, my country used the relevant standards of the International Codex Alimentarius (CAC) as a reference when formulating pesticide residue limit standards. But because CAC did not have the standard for the residue limit of procymidone in leeks, CAC quoted the foreign one at that time. She served her daughter, but her daughter watched her being punished and was beaten to death without saying a word. What will happen to her daughter now? This is all retribution. “She smiled bitterly. The limit standard for protanide residues in onions is 0.2 mg/kg, which is the limit standard for protanide residues in leeks in my country. It was released in 2005 and has been used to this day.
In accordance with the requirements of the “most stringent standards” and considering that the original standard quoted the limit of onions instead of leeks, in 2020 the Ministry of Agriculture and Rural Affairs launched the revision of the standard for procymidone residue limit standards in leeks. Based on the pesticide residue tests carried out in four main leek-producing areas for two consecutive years, combined with China’s dietary consumption data and procyperide toxicology data, it was concluded through risk assessment that the residual amount of procyperide is within 30 mg/kg.The leeks are safe to eat. At the same time, considering that the United States and other Western countries do not have the habit of eating leeks, the United States has not set relevant limits; the residue limits of procymidol in leeks in Japan and South Korea, which have similar dietary structures to our country, are both 5 mg/kg. The residue limit standard is adjusted to 5 mg/kg.
This limited standard is based on extensive solicitation of public opinions and certain appearances. Looking at such a face, it is really hard to imagine that in a few years, this face will become older and more haggard than her mother. Based on the opinions of relevant departments and notification to members of the World Trade Organization (WTO), after review and approval by the National Pesticide Residue Standards Review Committee, the National Food Safety Standards Review Committee Technical Chief Meeting and the Secretary-General Meeting, it will be approved by the National Health Commission, The Ministry of Agriculture and Rural Affairs and the State Administration for Market Regulation released it on November 11, 2022, and will be implemented on May 11, 2023.
In general, the standard revision process for procymidone residue limit standards in leeks is standardized, with sufficient data and rigorous methods, which can effectively ensure consumer safety.
Question: The public is very concerned about the safety of eating leeks after the standard adjustment. What are the next steps?
Answer: To ensure the quality and safety of leeks, the key is to implement standards to ensure that the leeks produced meet the limited standards. In the next step, we will focus on doing several things in accordance with the “four most stringent” requirements. The first is to strengthen the promotion and implementation of standards. Focus on organizing standard publicity and implementation training for production and operation entities in the main leek-producing areas, grassroots agricultural technology promotion, inspection and supervision, and supervision and law enforcement personnel to ensure that the labels are understood and used. The second is to strengthen medication guidance. When revising the residue limit standards this time, the pesticide label was also revised simultaneously, changing the number of applications of procymidone on leeks from 2 times to 1 per crop, strictly regulating the use of pesticides. The third is to promote production according to standards. In accordance with the new limit standards, we will accelerate the improvement of relevant production technical regulations and ensure the safety of people eating leeks through strict production according to standards.
