The agricultural disability standard is 25 times, can you still eat "leek fried eggs"?

Leek is a characteristic vegetable in China. It is loved by the Chinese because it has a unique flavor of spicy and delicious flavor.

It can not only make a dish separately -the grilled leek of the barbecue stall is called "men’s gas station"; it can also become ingredients to set off other dishes -for many people, whether it is vegetarian or meat filling dumplingsWithout leek, there is no "soul".

Because leeks are welcomed by the general public, their own safety issues have attracted much attention.In the market, the number of unqualified leek verified by the market supervision department is huge, most of which are related to a pesticide called "littering".

From May 11 this year, the national standard of compulsory food safety in my country in China has been adjusted from 0.2 mg/kg to 5mg/kg from 0.2 mg/kg.According to this calculation, the new standard is equivalent to regulating the remaining limit of mildew in the leek by 25 times.

Is this the standard of pesticide residues "relaxed"?Can the consumption safety of leeks be guaranteed after the standard adjustment?

Rotten effect is a low -toxic bactericide, which is widely used in the world to prevent and treat crops such as vegetables, fruits and other crops.Registration and use.

The acute toxicity of rot is low, and the semi -dying amount (LD50) is greater than 5000mg/kg of the acute meridian of rats. According to the standard of pesticide toxicity, WHO is determined as "no acute toxicity".my country’s pesticide registration agencies are comprehensively determined as "low toxicity", without teratogenic, carcinogenic, and mutagne.

Why is it found in leek?This is related to the unique growth characteristics of chives.

During the planting process, chives are often appropriate due to temperature and humidity conditions, which seriously affects the quality and yield of leek.

Hu Bin, a senior agronomist at the Beijing Plant Protection Station, told China News Weekly that chives with gray mold may occur in the production of leek in all parts of the country, especially in the production of protective places such as small arch sheds, greenhouses and greenhouses.Taking the Beijing area as an example, the rate of chives with gray mold disease in the suburbs of Beijing in the past 5 years is as high as 95%.And this disease has a long period of harm, which can occur from September to April of the northern region.In addition, gray mold can continue to harm during the storage and transportation of leek.

At present, the more effective method for preventing gray mold is ventilation and hygrometering and applying chemical sterilizers.

However, ventilation and moisture reduction are easily restricted by weather factors. When continuous cloudy, low temperature, and winding weather, the temperature in the shed is low and the humidity is high.The long -term high humidity environment in the shed will exacerbate the occurrence and spread of chives with gray mold, so there are many restrictions.

On the contrary, the production of shed is suitable for the use of smoke to prevent diseases. It is extremely easy to operate, the prevention and control effect is more intuitive, and it is more likely to be accepted by vegetable farmers.Therefore, the actual production of Chinese cuisine prevention and control of chives is more dependent on chemical sterilizers represented by rotten smoke.

my country has approved rot and mildew in 1993 to register on leeks, and in 2005, it determined the standard of 0.2 mg/kg for residuals, which has been used to this day.Among the latest "Maximum Residual Limited Limited Edition of 112 Pesticides, including 2,4-sodium sodium salt of food safety" (GB 2763.1-2022), the maximum residual limited edition of the mildew has been adjusted to 5mg/kg.

It is reported that on the basis of extensively soliciting social opinions, the opinions of relevant departments, and reporting to the World Trade Organization (WTO), the Standard Review Committee of the Standards for Food Safety Standards and Secretary of the National Standards for Food SafetyThe long -term conference was reviewed by the National Health and Health Commission, the Ministry of Agriculture and Rural Ministry, and the State Administration of Market Supervision on November 11, 2022, and implemented it on May 11, 2023.

According to this calculation, the new standard is equivalent to regulating the remaining limit of mildew in the leek by 25 times.

In Hu Bin’s view, the adjustment of this standard is more of a reasonable revision.

Before the new standard was promulgated, he had called on the complexity of the issue of leek corruption and mildew more than once, and it was recommended to reasonably adjust the maximum residual limited standard of mildew in the leek."Whether it is a foreign developed country or other vegetable crops and fruits in China, our previous standards appear too harsh. It is almost as long as the leek production season is used in the production season."

According to pesticide labels, the safety interval of the mildew on the leek is 30 days, and it is used up to 1-2 times per season.However, the single stubble of the protective ground leek usually takes about 30 days, or even the fastest stubble only takes about 23 days.This means that the use of rot mildew strictly and frequently to prevent the treatment of chives with chives with high mildew, which has a very high risk of farmers’ residues.

With reference to the restrictions on other crops on mildew, you can feel the harsh of the original standard more intuitively.In my country’s national food safety standard GB 2763-2019 "Maximum Residual Limited Edition of Food in Food", the maximum residual limited limit for the maximum residue on the leeks is equivalent to 1/10 of tomato and cucumber, 1/10 of eggplant, pepper and grapes/ 25. 1/50 of strawberries is much higher than other fruits and vegetables.

In fact, the previous standard quotes onions rather than the limited edition of leeks.

According to the relevant person in charge of the National Pesticide Residual Standards Standard Review Committee, in 1993, my country approved the registration of mildews on the leek, but at that time, the scientific research foundation was weak, and the limited edition of the rotten mold residue in the leek has not been formulated.At the beginning of this century, due to the lack of pesticide residue test data, my country used the relevant standards of the International Food Code (CAC) as a reference when formulating a limited standard for pesticide residues.However, because CAC does not have limited standards for rot mildew residues in leeks, at that time, the limited limited standard of rotten mold residue in the CAC onion was quoted by 0.2 mg/kg.Essence

Too rigorous standards directly lead to the case where leeks are overweight.

From the official website of the Ministry of Agriculture and Rural Affairs, the Department of Agricultural Product Quality and Safety Supervision has analyzed and summarized the unqualified sampling inspections of the consumption agricultural product market supervision department in 2020, showing that in 2020, a total of 14,295 batches of 14,295 batch of 14,295 batchs of the General AdministrationAmong the sub -agricultural products, 3,799 batches of consumption agricultural products were not qualified, accounting for 26.57%.Among them, the rotten profits exceeded the standard of 352 batches, all of which were detected from leek.

"The old standard is too harsh, and the difference in scientific medication levels can no longer be distinguished by planters, resulting in the difficulty of mildew in the production of leek, increasing the difficulty of leek management and production costs, and affecting the development of the leek industry. Therefore, the original will be the original.The reasonable adjustment of standards is more active amendment. "Hu Bin pointed out.

For consumers, the most concerned issue is the standard adjustment, will it lead to the increase in security risks?

In this regard, Ruan Guangfeng, deputy director of the Center for Food and Health Information Exchange Center, said that the adjustment of this value is also based on food safety risk assessment and the actual situation of the industry.

It is reported that in 2020, the Ministry of Agriculture and Rural Affairs launched the revision of limited limited standards in leek.On the basis of the four consecutive years of pesticide residue tests in the four consecutive years, combined with China’s dietary consumption data and corruption toxicology data, it can be found that the leege of leeks that are less than 30mg/kg are less than 30mg/kg.It can be eaten safely.

At the same time, considering that there is no habit of eating leeks such as the United States and other Western countries, the United States has not formulated relevant limits; the residual limited quantities of mildew and mildew in Japan, which are similar to my country’s diet structure, are 5mg/kg. The limited limited standard of the middle rot is adjusted to 5 mg/kg.

Ruan Guangfeng further explained that in the specific application of agricultural products, it will be adjusted according to the effective situation of insecticide in the actual application and the intake of the extreme consumption of this agricultural product.For example, if a person eats four or five pounds of chives a day, if the agricultural residue intake in this extreme situation is far within the safe dose range, then this limited value standard can ensure safety.The adjustment of the divertal value of the leeks this time is to adjust according to this principle.

So, will the standard adjustment indirectly lead to the increase in farmers?

The relevant person in charge of the National Pesticide Residual Standard Review Committee specifically stated that the pesticide label was also revised simultaneously during the revision of the residual limited standards, which changed the number of medicinals of mildew on the chives from two times to one time, and strengthened it to once, strengtheningDrug guidance, strictly standardized medication behavior.By producing strictly in accordance with the standards, the safety of people eat chives.

"In general, the amendments to the amendments to the limited standard revision of the mildew residue in the leek, the data is sufficient, and the method is rigorous, which can effectively ensure consumers’ consumption safety." The person in charge said.

my country is a large agricultural country. It has a variety of agricultural crops. For the current scientific and technological level, pesticides are still the most effective weapons for preventing and treating diseases and insect pests.

The Institute of Plant Protection of the Chinese Academy of Agricultural Sciences has issued a statement that compared with other plant protection measures such as agricultural prevention, biological control, and physical control, pesticides have the advantages of wide adaptation, easy operation, huge scale, fast effect, and significant effects, especially when they are some of them.When a harmful creature is about to outbreak, chemical prevention and control are often the only effective measures that can be optional.According to statistics, improper medication or stop taking medicine can cause crop production to reduce production by 35%-40%, of which fruit and vegetable loss can be as high as 40%-60%.

Of course, while the chemical pesticides benefit for humans, they also have side effects that do not meet human interests. The most important side effects are the toxicity of people, animals and other beneficial creatures, which also causes the public to talk about "medicine" color changes.

In fact, my country’s pesticide safety has been greatly improved.The "2023 China Agricultural and Rural Development Trends Report" pointed out that as of the second quarter of 2022, the national pesticide usage was 248,000 tons (fold), a decrease of 16.8%compared with 2015, and maintained negative growth for six consecutive years. At the same timePesticide accounts for 85%.

In 2022, the Ministry of Agriculture and Rural Affairs organized two national agricultural product quality and safety routine monitoring work, and sampled 106 varieties of 106 varieties including vegetables, fruits, tea, livestock and poultry products, and aquatic products.The rate is 97.6%.This is also the seventh consecutive year that the qualification rate of the quality and safety of agricultural products in my country has remained above 97%for the seventh consecutive year, and the overall shows a stable development trend.

However, it should be pointed out that the adjustment of the mildew standards this time also exposed the shortcomings of my country ’s chives related to pesticide -related pesticides.

Objectively speaking, the problem of leek and mildew residues exceeds the problem. It is difficult to prevent the prevention and treatment of gray mold diseases, the low medicinal level of farmers, and the previous standards of agricultural residues are too strict.An important reason for this problem.

At present, the sterilizers registered in my country are relatively single.It can be seen from the China Pesticide Information Network inquiry that the diseases on the leek in my country are only gray mold, and there are 17 products in a total of three products, including three effective ingredients of mildew, mildamine and percorbin. Among them, 嘧Meimine is a newly registered product in June 2020, while the macroeaches are newly registered in April 2022.

In other words, for a long time, in my country, only one effective ingredients have been registered in the prevention and control of chives in gray mold.

In contrast, there are currently 267 registered pesticide preparations for tomato gray mold, 159 pesticide preparations for cucumber gray mold, and nearly 20 sterilizers covering the sterilizers.

Long -term use of a single ingredient pesticide will increase the problem of anti -drug resistance, and then exacerbate the problem of over -the -standard residue on the leeks.In this regard, a research person in the agricultural field told China News Weekly that a variety of active ingredients mixed, alternating sterilizers and stopping the use of anti -drug problems is the main method for governing fungicides.The premise of implementing these methods is to accelerate the registration of new drugs for chives.

"The competent department of pesticide registration should strengthen the guidance of policies and projects, and encourage and support pesticide enterprises to carry out the registration of new drugs for preventing and controlled chives, especially high -efficient low -toxic bactericides, re -entered preparations, and convenient application mechanisms.Smokers, etc. "The above -mentioned researchers suggested.
