According to newspaper reports of the CPPCC, for the community made all kinds of genetically modified food challenge, March 3, the CPPCC National Committee members, transgenic insect species, should be cautious about the promotion. . the body to increase its photosynthetic efficiency. Yuan Longping, as long as two generations, there are problems, it means that GM food is safe.
see this report, first of all I am very happy because I am not the only one on the switch to BT rice proteins are concerned I am not a person. However, I still worry about the conversation as Yuanyuan Shi. because of his attitude to GM is not comprehensive, did not fully consider the health of all human beings, especially the talk from the perspective of immunology. He considered that , as long as the gene to be at the mercy of food to other food in, it does not require security, in particular the assessment of immunity, this is very dangerous. In fact, in daily life, we often ignore the issue of Immunology that individual differences in our population immunity issue. If I tell you, in fact, our human, someone will food allergies, you may be surprised. However, according to U.S. data, Americans for peanut allergy up to 1.5 million people, along with over eating McDonald's fries doped with wheat gluten caused a false case of asthma. And because of our staple food of mankind there are many, so we can avoid their own staple food allergies, and select the appropriate their staple food. without making any assessment of the genes to other crops put the staple food in some people may lead to loss of staple food, and had to pay high prices to choose non-GM staple food, even as knowledge of the disease, even death. nature to the existence of many such examples, such as population, some people sensitive to red blood cells for the broad bean, broad bean caused by disease, resulting in hemolysis, or even death. nature, these examples exist, we can not eliminate, but if we artificially create these harmful plants, is not it regrettable and sad that? And to most people's interests, could ignore the life and death of innocent people do? the same time, I do not think, 2 on behalf of the people do not have problems to that GM food is safe. because it can not be evaluated, many problems may be unable to understand our knowledge and evaluation now, especially agricultural experts were unable to evaluate. For example, in the South Pacific island nation, the residents will consumption of the brain dead, and that it is delicious. And from generation to generation, far more than two generations, probably more than 20 generations have, we all think is safe. However, it was fashionable in the local generation known as disease similar to mad cow disease, patients with nerve damage, paralysis and eventually death. Later, scientists found that this is due to infectious diseases caused by consumption of the brain. Thus, the local people no longer eat the brain. A diet can be change, but once GM crops are not seriously polluted the natural world, even if we found out the reason, but also how to do it?
see here, is not suggested that Mr Yuen is more conservative than I, more opposed to GM? I do not think so. In fact, I have repeatedly stated before, I am not against GM, and I too do genetically, but not in the tricks in our food, because it is dangerous and must be careful. In my opinion, our country's agricultural experts for GM it is really arrogant and ignorant, even in the illegal operation, may have led to serious consequences, but do not know. First of all, both the Ministry of Agriculture or the experts agree that BT proteins security reasons turned out to be BT centuries and no one opposed to agricultural use, as well as the short-term experiments in mice. you know, a lot of things we use for a long time is not necessarily safe, such as tobacco. and survival of mice is much shorter than humans, the experimental results This long-term consumption of food substances, can only say that a reference of it. So if we really want to switch to BT gene into rice, it is necessary first to scientifically prove its security, and the allergic population. Therefore, I think BT should carry out toxicity studies of quantitative, rather than rush to GM. I think, first of all experts in the Ministry of Agriculture and the Ministry of Health should apply to be included in the BT protein in the range of food additives, and in accordance with laws and regulations on toxicity studies. after passing through the approval should be piloted in some areas of food added, Wuhan City, Hubei and I think is very good, a lot like the , as long as approved by the Ministry of Health, and to add rice by BT in the form of food additives and personally experience the security of the. At the same time, volunteers can call BT protein in the skin and gastrointestinal sensitive test to assess the safety of the people. This is of course only evaluated the safety of their own BT protein, the next step and then assess the safety of gene transfer. our national scientific research has always been no organization, the GM is a mess, was transferred to the BT gene had at least 5 or more, and do not have any security goals the stage, there could not be evaluated, so what is scientific research. So I think there should be a step, have a plan it can. Agriculture Ministry said that China had not ratified and the planting of genetically modified food, has approved only four kinds of cotton genetically modified raw materials. Then I said, they may have led to disaster, is not in the sensational? I am very worried. because I found that some people are allergic to the cotton fabric will, cause dermatitis and other issues, but we did not indicate whether the clothes turn genes. At the same time, we use the medical cotton products, such as sterile cotton ball, gauze, and accessories, etc. , whether it is genetically modified, whether the patient therefore allergy, leading to wound infection, healing problems, and even endanger over life? we may even many medical supplies are transgenic, and transgenic protein content is much, do not know. I Preparation of monoclonal antibody against BT first is to detect medical supplies made in the BT content, but because I was aware, the relevant departments will not care and are willing to know the results, so I gave up the idea and the monoclonal antibody. But it does should be the responsibilities of the health sector. So, I think, relevant departments of our country should be investigated and re-approval of GM products for clinical use, and should be marked and identity management. This can be confirmed by BT for the provision of protein allergy reference.
So, I think, no matter what we turn, must be clear, we turn what is, what people, what harm might be, it is the only responsible. and our natural antigen for the immune system changes, the most sensitive, should be the first object of concern.
Although, as a CPPCC member said, living law, because it is possible that you have been used genetically modified medical supplies or clothing, or even women's products, and have had a bad reaction or have been sensitized by. because unfortunately, our Ministry of Agriculture, Ministry of Commerce and the Ministry of Health do not provide genetically modified products should be identity. Therefore, GM crops is a serious matter, everyone can not escape, and because individual differences in the immune system, who is the victim but not because it is not people, is not a government official, there is no money, and is not CPPCC National Committee members to decide. This can only give you the natural world and those of experts to determine the GM.
