In the context of growing disputes over genetically modified foods in various countries around the world, an investigation report by the International Herald Tribune on the possibility that animal genetically modified corn in Shanxi and Jilin may cause anomalies has triggered heated discussions and concerns.
According to the announcement of the Chinese Agricultural Department, Xianyu 335 is a hybrid corn selected by the American Pioneer Corporation. The United States patent record shows that the category number of the male parent PH4CV of a large number of seeded maize seeds of Xianyu335 is indicated as a transgenic crop. Almost all kinds of animal abnormal reactions in Shanxi, Jilin and other places have eaten this kind of corn. The local farmers gradually got used to this kind of anomaly, but the media could not ignore it.
Genetically modified foods have caused animal reactions in other countries. Animal genetic abnormalities similar to those in Jinzhong and Zhangshu have been found in transgenic animal experiments in various countries. Among them, documents published by the U.S. National Academy of Sciences and the U.S. Department of Health indicate cases of abnormalities in the use of genetically modified feeds in various parts of the world, including abnormalities in visceral rats, pseudopregnant or infertile pigs, and abnormally dead cows. After the emergence of genetically modified soy foods in the UK market, residents' allergies have risen by 50%, and Brazil has seen the same situation.
Independent tests in some countries have revealed that GM food-fed animals have kidney and liver damage, problems with the reproductive system, and abnormal immunity. This type of large-area and multi-regional similar abnormal reaction is not just caused by changes in environmental factors. Genetically modified corn We are conducting real non-simulation tests in our country.
"Xianyu 335" was officially promoted in China in 2004, and it began to be popular in 2006. It has taken a strategic position in China. In a few short years, it has occupied more than half of Shanxi's corn. In the three provinces of East China, this figure is also very alarming. Some industry companies estimate that “Xianyu 335†has occupied 70% to 80% of the market share, and Wang Xiangkun, a professor of plant genetics and breeding at China Agricultural University, believes that it is at least 50%.
In the national spring corn area, in 2009, the plant area of ​​Xianyu 335 reached 24 million mu, ranking second in the country's corn seed sales; it is expected to reach 35 to 45 million mu in 2010, accounting for 1/1 of the country's total corn planting area. 10. So far, relevant government departments have not publicly stated that they allow large-scale planting of GM food crops.
While the Xianyu 335 is rapidly expanding, some of China’s traditional seed resources are being lost. Shanxi is a large province with a rich corn seed, and the seed industry concerns the issue of food security in our country. If Pioneer controlled the provenance of Shanxi's 10 million mu, it would be free to raise prices. What is even more worrying is that if the pioneers don't provide seeds, there will be a huge shortage of provenances.
From a scientific point of view, GM technology is seen as the future direction of agriculture, but the controversy it raises cannot be ignored: Many animal experiments that have been published prove that consuming GM foods is risky. After all, this is a young technology. In its nearly 20 years of application to real life, mice have been multiplying for generations, and humans have not yet experienced a life cycle. Europe has adopted a boycott attitude towards genetically modified foods. Many institutions and academic organizations in the United States have also issued research reports to warn of the harms caused by GM crops to agriculture and health.
“Xianyu 335†has been popularized in China for 5 or 6 years. Rats have passed more than 20 generations and pigs have passed 3 generations. This is only one-tenth of the life cycle of humans. A serious reaction occurred.
After the “International Herald Tribune†reported, the Shanxi Provincial Department of Agriculture quickly posted news on its official website that it had lost the scientific basis for investigating the causality described in the report. First, the Xianyu 335 corn variety is a hybrid variety identified through national breeds, not a genetically modified variety. The second is that the abnormal phenomena of animals such as pigs, sheep, and mice reflected in the report are inconsistent with the facts. It is believed that this phenomenon has occurred in a small number of farmers and its causes are complex, involving many factors such as management, disease, climate, and nutrition.
The author believes that the issue of official and slow negative reports raises the issue that the discovery of genetically modified crops is not a bad thing. It can warn us and allow us to focus on the research and response to these risks that are not conclusive.
Monsanto, the world's giant of genetically modified crops, was forced to report for the first time its raw data on toxicological experiments conducted on three types of genetically modified corn. The scientists analyzed the data and found that the consumption of genetically modified corn caused damage to the liver and kidneys. The results of the study were not announced due to government intervention.
Our country is authorized to import GM foods, and whether genetically modified crops will cause harm to China's agricultural production and food safety is an important matter that urgently requires the government and scientific research departments to intervene. China’s soybeans were once self-sufficient, but soon became the world’s largest soybean importer. Now more than half of US soybean exports are imported by China. From 2005 to 2009, China’s cumulative imports reached 166 million tons, and most of them were genetically modified. Soybeans. China is a world leader in corn production and consumption. Its annual output and consumption are all over 150 million tons. This year, COFCO imports large quantities of U.S. genetically modified corn, and corn may have a tendency similar to that of soybean.
The uncertainty of the safety of genetically modified crops has caused public concern. I do not know how the country evaluates the safety of these US soybeans and corn. In past experiments, it was found that two types of transgenic maize from the United States are harmful to animals. Although they are used as feed, are they harmful to humans after transformation? In addition, GM maize may also have environmental impacts on the growing area. (Lildon)
