Although genetically modified foods are safe for the public, there are doubts

These scientific organizations think: Transgenic is safe

Lanzhou Evening News reporters witnessed the international seminar on the development and prospects of global transgenic crops

When talking about genetic technology and genetically modified foods, many people will have many things to say. There are many posts about genetic modification on the Internet and Weibo WeChat, and the voices that oppose genetic modification are also very powerful. Some people will turn against each other, there are many people who follow the trend, and many people are skeptical, because this problem involves many professional knowledge after all. No question or not.

For GM, we want to know a lot. We understand a lot of voices that oppose genetic modification (hereafter referred to as “reversal”). To understand the international situation, we also want to learn more from the international community and the scientific community. On October 16th and 17th, the International Symposium on Global Development and Future Prospects of Transgenic Crops, sponsored by the Chinese Academy of Sciences and the American Academy of Sciences, was held in Wuhan Huazhong Agricultural University. From the United States, the United Kingdom, Brazil, South Africa, the Netherlands, Switzerland, Mexico, India and China, more than 10 countries, 19 scientists of global biotechnology research and development attended the meeting. It also gave us an opportunity to have a full range of face-to-face exchanges between media professionals who have participated in the national media GM workshop and GM experts from all over the world.

In the end is the genetic modification the same as Weibo? Is there an international authority on the safety of genetically modified food?

Peter Raven, deputy dean of the National Academy of Sciences and Honorary Chairman of the Missouri Botanical Garden in the United States, explained this in detail. Internationally, it is authoritative to conclude that genetically modified organisms and their products that have passed safety assessments and safety certificates are safe. The GM foods that are approved for listing are the same as the traditional non-GM foods—essentially equivalent.

The World Health Organization (WHO) believes that “at present, there is no report that the general public of the GM food-approved countries have any impact on human health after eating GM foods”.

The Organisation for Economic Co-operation and Development (OECD) and the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) convened an expert seminar to issue the conclusion that “all genetically-modified foods currently listed are safe”.

So why did the "reverse" sound come from? Let's take a look at how people in the industry say it.

Focus questions

"Reversal" sounds a lot. Why does China still need to promote genetically modified crops?

The Department of Science and Technology Education Division of the Ministry of Agriculture, Director of the Department of Safety Management and Intellectual Property, Geng Jianping answered questions from reporters: The main reason is that there is a gap in the food produced by our country. Population growth has intensified the demand for food. The total area of ​​cultivated land in China is close to the “red line” of 1.8 billion mu. In 2013, China’s total grain output exceeded 600 million tons, but its consumption reached 680 million tons. In 2013, China imported more than 90 million tons of grain, including about 63 million tons of soybeans, which can only provide 18% of the demand in China. The security risk has increased rapidly. The current situation of traditional agriculture in China is to ensure that production needs to use a large amount of chemical fertilizers and pesticides. According to data from the National Bureau of Statistics of China, there has been almost no increase in rice yield in the past 20 years, but the use of chemical fertilizers and pesticides has doubled. In many cases, chemical fertilizers have reached an annual usage of 58 million tons, which is the highest in the world. The amount of pesticides applied is 1.8 million tons, which has a relatively large impact on the environment. The transgenic crops are more resistant to high quality and high yields, which is an effective way to ensure the sustainable development of China's agriculture. If we do not develop, we will fall behind. This means we must buy more agricultural products from abroad.

Can genetically modified food be eaten?

Ji Jianping, director of the Department of Science, Technology and Education of the Ministry of Agriculture’s Department of Safety Management and Intellectual Property of Genetically Modified Organisms, said that there are many professional research institutions for genetically modified organisms in China. Those genetically modified foods that have obtained safety certificates through safety evaluation are safe and can be eaten with confidence. Is the safety of genetically modified foods inconclusive? Lou Jianping said that the safety of genetically modified organisms should be the final decision of a professional authority. "The safety of genetically modified foods is conclusive." Yan Jianping said with certainty that the safety evaluation of genetically modified foods follows the principle of case analysis and cannot be used to talk about the safety of genetically modified foods. To date, there has been no confirmation of genetically modified foods. Food safety issues. Has been safely studied in the past 40 years, safe food for 18 years.

What is the development trend of GM crops in the world?

Xu Zhihong, former president and academician of Beijing University, said at the International Symposium on the Status Quo and Future Prospects of Global Genetically Modified Crops that the total area of ​​genetically modified crops in the world has exceeded the total area of ​​Chinese farmland, and that there are 27 kinds of genetically modified crops approved worldwide. The main four are soybeans, corn, cotton and canola. In 2013, the area under cultivation of genetically modified crops exceeded 178.2 million hectares. In 2013, Brazil was the country with the largest increase in GM crops. It has been at the forefront for five consecutive years. Last year, the planting area of ​​GM seeds increased by 3.7 million hectares, making it the world’s second largest producer of GM crops. The United States accounts for 40% of the world's GM crops, and China has 4.2 million hectares.
