Dye aspects of malachite green

Suggestions for effectively solving the problem of malachite green. To fundamentally solve the safety problems of aquatic products including malachite green, the government should vigorously do a good job in the following aspects. (1) Vigorously promote healthy, ecological and safe aquaculture methods, build "responsible fisheries", and improve the quality of employees. "Responsible fisheries" mainly includes water quality testing, disease prevention, scientific medication, quality testing, etc. in the aquaculture process. It also includes employees in various aspects of breeding, processing, transportation, sales, etc., who must be responsible for the eating safety of aquatic products and ensure that Provide consumers with safe and secure aquatic products; at the same time, attention should be paid to environmental protection during the production process, taking into account immediate interests and sustainable development of the industry. (2) Promote the construction of an internationally accepted food safety system (HACCP) and establish a traceability system for aquatic products from the table to the farm. The ultimate goal is that every aquatic product consumed by consumers can be traced to the seller, processor, transporter, and breeder, and a complete HACCP control system is established in all aspects of the sales, processing, transportation, and breeding of aquatic products. (3) The state further strengthens the management of aquatic drug safety, widely publicizes aquatic drug management regulations, accelerates the implementation of aquatic drug prescription systems, and improves the technical level of prevention and control of aquatic diseases. At the same time, penalties for illegal drug use should be strengthened, and those responsible for selling and using prohibited substances should be effectively investigated and punished. Those who violate the regulations will have their veterinary drug business rights and aquatic product breeding qualifications revoked to ensure the health and safety of consumers.

Research institutes should do this from the following aspects: (1) Make use of the technical advantages of scientific research institutes to research and develop pollution-free fishery drugs (such as high-efficiency disinfectants, water quality improvers, microecological preparations, Chinese herbal medicine, etc.), eliminating highly toxic and high-residue drugs so that farmers can have medicines available. (2) Establish "Good Aquaculture Practices (GAP)", research and promote new breeding technologies and models, and achieve the purpose of effectively avoiding or reducing the occurrence of diseases by optimizing the breeding environment and other measures, thereby reducing the use of drugs.

Huang Zhibin: Cut off the supply chain of malachite green and increase drug research and development (Chief Researcher of the Aquatic Economic Animal Disease Prevention and Control Research Center of the Pearl River Fisheries Research Institute) The crux of the problem of malachite green being banned. It is understood that the use of peacock Stone green is used in the breeding and transportation of aquatic products.

The main mentality of users is: ① used for the prevention and control of diseases such as common saprolegnia and some parasitic diseases; ② transportation and preservation. Users are well aware that malachite green has been listed as a banned drug, but it is still used.

The main reasons are as follows: 1. Users have an indifferent sense of social responsibility: they are fully aware of its toxic and side effects, are profit-driven, are greedy for cheap, and use low-priced contraband to reduce personal losses and cause social harm. 2. Market supervision is weak and the malachite green supply chain still exists. The Ministry of Agriculture’s Announcement No. 193 and the implementation of the new Veterinary Drug Administration Regulations have clarified the consequences and penalties for the sale and use of prohibited drugs. But no penalties were actually imposed. In addition, the supervision method is not suitable for bad suppliers who fight "guerrilla". As long as it is available on the market, people will voluntarily take the risk to use it. This is the key reason. 3. The research, publicity and promotion of malachite green substitutes and pollution-free, efficient and low-toxic fishery drugs need to be strengthened. In fact, the therapeutic effect of malachite green is not special. There are currently some alternatives with good effects, but the price is more expensive than malachite green, so farmers do not want to use it. Therefore, as long as there are cheap illegal drugs on the market, such as malachite green and furazolidone, dealers will be less enthusiastic about promoting alternatives, and it will be more difficult for companies to promote new products. Of course, aquatic animal parasites are highly drug-resistant, which is also a factor causing the abuse of illegal drugs. 4. It is difficult to protect the market of high-quality aquatic products: if you are sick, you must take medicine, and the cost and effectiveness of medicine must be considered. The price and sales volume of non-toxic and residue-free aquatic products cannot be guaranteed, which will inevitably lead to a one-sided focus on costs and benefits. It is also a factor in the abuse of cheap illegal drugs. Malachite green can be completely replaced by other drugs. From the perspective of disease control drugs, the use of malachite green as aquatic drugs is not irreplaceable.

Suggestions for effectively solving the problem of malachite green: 1. Strengthen supervision and management of circulation and use, and introduce some tough measures. 2. Strengthen publicity to make fishermen fully aware of the hazards of malachite green. 3. The state must increase investment, not only in malachite green, but also in the rectification of other banned drugs. The green aquatic products and pollution-free aquatic products we are now advocating do not mean "without drugs". Because the development of the breeding industry is moving toward intensification, the use of drugs is inevitable, so investment in drug research must be increased. Regarding the research on malachite green alternative drugs, the state should provide certain funding. It is not necessarily difficult to develop and launch new drugs, but it will be difficult if we rely solely on private research and allow them to be promoted naturally. 4. Scientific research units should increase applied research, starting from solving some basic problems in actual production. 5. Call on the government to pay attention to the problem of drug residues such as "malachite green", strengthen the quality and safety management of aquatic products, and promote the healthy and harmonious development of the industry. Ye Jinyun: Strengthen supervision and improve the quality of employees (Director of Zhejiang Fisheries Research Institute) The crux of the problem of banning malachite green: 1. The harmfulness of malachite green was only discovered in recent years, but before that, this product It is widely used in the prevention and control of fungal diseases in aquaculture, and is cheap and effective. At present, there are still a large number of previously published relevant professional publications, popular science books and other materials circulating in the society. Once most aquaculture farmers discover common fungal diseases such as "water mold", the first control method they think of is to use "peacock" "Malachite green" is used for treatment, because in a sense, "malachite green" is a special medicine for controlling "water mold". This view is deeply ingrained and difficult to change in a short period of time. 2. Although the country has explicitly banned "malachite green", the production, circulation and use of this item are still not well managed. The crude product of "malachite green" is a chemical dye - alkaline green, which can be purchased in any chemical dye store. 3. The publicity and education to the majority of aquaculture farmers is not in place. Our country is a developing country, and the cultural quality of most breeders is not high. It is difficult to understand and accept this ban to a satisfactory level. Some use it knowingly, and some have insufficient understanding of the harm. Some simply don't understand this ban. Suggestions for effectively solving the problem of malachite green. Since the current research on "malachite green" alternatives is mainly corporate activities, the human, material and financial resources invested are limited. Therefore, the depth and breadth of product research are There are also considerable limitations, and it is difficult to meet the requirements of society. Our country is a big aquaculture country. To develop into a powerful aquaculture country, there are still many similar problems that need to be solved, and "malachite green" is just one of them. Therefore, based on long-term development considerations, the main tasks that the government and scientific research institutes have to do are: 1. Strengthening the operation and management of aquatic drugs is a top priority. Compared with veterinary drug companies that have implemented GMP management, the operation and use management of veterinary drugs (aquatic drugs) are not strong enough, and the management of users will be more difficult. 2. Strengthen investment in special research. Our country has a huge market demand for this type of product. Only when corresponding products are on the market can it be possible to replace or ban a certain product, otherwise it will be difficult to achieve results. 3. Strengthen education for the vast number of producers, operators and users, and continuously improve the quality of employees. 4. Relevant research institutes and enterprises should jointly tackle key problems and do corresponding basic work to provide guarantee for government decision-making and product promotion. The national competent authorities attach great importance to fully responding to "malachite green". In recent years, the Ministry of Agriculture has attached great importance to the quality and safety of agricultural products, and organized and carried out certification of pollution-free aquatic products, certification of pollution-free breeding bases, fishery medicines, aquatic seedlings, fish feed and other agricultural products. To fund anti-counterfeiting activities, the central government allocates 6 million yuan every year to monitor drug residues in important aquaculture products.

In order to cooperate with the promulgation and implementation of the newly revised "Regulations on the Administration of Veterinary Drugs", the Fisheries Bureau of the Ministry of Agriculture also organized the preparation of the "New Fishery Drug Manual", "Must-Read for Fishermen", "Aquatic Product Quality and Safety Management Manual" last year, and carried out various levels of held fishery drug management seminars and training activities, and drafted the "Guidelines for the Use of Fishing Drugs" and the "Code of Conduct for Responsible Aquaculture", aiming to positively guide aquaculture producers to adopt healthy breeding methods, reduce the occurrence of aquaculture diseases, and strengthen aquaculture Quality process management. This year, the Ministry of Agriculture also issued the "Notice on Issuing the Monitoring Plan for Veterinary Drug Residues in Animal Products for 2005," requiring the issuance of a monitoring plan for veterinary drug residues in aquatic products for 9,390 batches throughout the year. Recently, the Fisheries Bureau of the Ministry of Agriculture organized the Fisheries Technology Promotion Station and the Fisheries Science Research Institute to go to Guangdong, Hainan, Beijing, Tianjin, Hebei and other places to carry out inspections on the quality and safety of aquatic products. These efforts have promoted the establishment of aquaculture quality and safety testing systems in various regions and strengthened the fishery administrative departments at all levels to manage the quality and safety of aquaculture products. However, aquaculture quality and safety management is a systematic project involving multiple links such as production, sales, and use. It requires the coordination and cooperation of multiple management links such as market, transportation, and breeding, as well as animal husbandry and veterinary, fishery, sanitation, quality inspection, Industry and commerce, public security and other departments participated.

The reporter learned from the Fisheries Bureau of the Ministry of Agriculture that in order to strengthen the rectification of the use of banned drugs in aquaculture with a focus on malachite green, the fishery authorities will focus on the following work in the future:

(1) Strengthen the publicity of laws and regulations and the popularization of knowledge on safe medication in aquaculture. Fishery administrative departments, aquatic technology promotion departments and disease prevention and control centers in various places are required to go deep into breeding enterprises and ponds and ponds to explain the basic knowledge of disease prevention and medication to breeding producers, and provide specific guidance on the use of drugs in the breeding production process. Supervise fishermen to scientifically prevent diseases and use drugs rationally in accordance with relevant regulations and standards for safe use of drugs in aquaculture, improve aquaculture producers' knowledge of safe drug use, and establish quality and safety awareness.

(2) Promulgate the "Code of Responsible Conduct for Aquaculture" and "Specifications for Safe Medication Use in Aquaculture" as soon as possible, carry out pilot work on aquaculture quality and safety management, promote healthy farming models, and increase technical regulations for pollution-free aquaculture. and the implementation of industry standards, guide farmers to feed rationally, manage water scientifically, and use medicine safely, improve the level of comprehensive management of breeding production, and reduce the occurrence of breeding diseases as much as possible.

(3) Carry out special rectification activities with the veterinary authorities on malachite green and other banned drugs in aquaculture. Based on the self-inspection situation of each locality, an inspection team was formed to conduct spot checks on the rectification situation in each locality, focusing on the implementation of the "Regulations on the Administration of Veterinary Drugs" and other relevant regulations and standards in the breeding process, and urged the establishment of a breeding production log and a breeding drug recording system to effectively promote Supervision and management of pesticide use in aquaculture.

(4) In the near future, it is planned to organize the relevant aquatic product quality testing center to conduct a spot check on malachite green drug residues in key breeding areas and key breeding species, and the results of the spot inspection will be announced. At the same time, fishery administrative departments at all levels and fishery and fishing port supervision and management agencies are required to strengthen the supervision and investigation of aquaculture drugs in accordance with the "Regulations on the Administration of Veterinary Drugs" and other relevant laws and regulations, and effectively perform the supervision and inspection of aquaculture drugs and other laws and regulations. Responsibilities.

(5) The first batch of malachite green tests to be included in the routine testing indicators for aquatic product quality and safety in the five major cities of Beijing, Tianjin, Shanghai, Guangzhou and Shenzhen.

Thoughts brought to us by “Malachite Green” 1. What kind of long-term mechanism is needed to ensure that consumers can eat “safe fish”?

2. From "chloramphenicol" to "malachite green", it should be said that each disturbance is not accidental. Our government is always very passive in raising a problem and busy responding to a problem. This gives We raise the question of how to establish and improve aquatic product safety early warning mechanism to nip problems in the bud? 3. As early as 2002, the country banned the use of "malachite green" in fishery production and operation. However, why does the research on its substitutes lag behind the development needs of production? 4. Why are the relevant announcements from the Ministry of Agriculture and the new "Veterinary Drug Administration Regulations" clear about the consequences and penalties for selling and using prohibited drugs, but the penalties have never been actually implemented. 5. As a dye, malachite green is a "banned" product in the fishery industry. How to effectively restrict the sales process? Should we implement a monopoly with reference to hazardous chemicals? The quantity and destination of transactions should be recorded. This is also a test paper that tests our ability to govern. This magazine calls for: Compared with other animal-derived foods, aquatic products have high nutritional value and delicious taste, and are welcomed by consumers. Good quality and safety are also important reasons for their popularity. The safety of aquatic products has always been an issue that people are more concerned about, and it is also the top priority of the fishery authorities. To maintain the dominant position of aquatic food in people's diet, the government, scientific research institutions and the majority of fishery producers must work together! Unsound systems can be improved, and backward concepts can be updated. To develop the aquaculture industry, we must have scientific, healthy and harmonious concepts. The majority of fishermen friends are the main body of the development of the aquaculture industry, the promoters of the industry, and the ultimate beneficiaries. We have the responsibility and obligation to maintain the image of our industry and abandon all activities that are detrimental to the development of the industry and the health of the people. Putting an end to the use of banned drugs like "malachite green" is related to the life safety of the general public. As a breeding producer, operator and manager, everyone should shoulder their own social responsibilities! Building a harmonious society is the theme of development in today's era. Various industries and departments involved in aquatic product management should form a unified thinking to achieve the most appropriate embodiment of management, make management smoother, and provide the best guarantee for the development of a harmonious society!
