How much do you know about genetically modified corn, and how do we deal with it?

It is understood that Mexico currently bans the planting of genetically modified corn; EU suspends imports of genetically modified food; Japan, Australia, New Zealand and other countries all require genetically modified foods to be clearly labeled to indicate the content of genetically modified ingredients; Many large supermarkets in the UK prohibit the use of GMOs as raw materials in the production of food. There are examples of the dangers of genetically modified corn in countries around the world

1. As early as 1999, John Losy, a researcher at Cornell University in the United States, also published a report in the British journal "Nature" that fed spotted butterflies with leaves coated with transgenic BT gene corn pollen, resulting in the death of 44% of the larvae.

2. In Brazil, the cultivation of genetically modified crops began many years ago, resulting in a large number of Brazilian women being infertility, with an infertility rate of 44%.

In 2002, there was a "genetic contamination of corn in Mexico" and in 2002, there was also a "genetically modified corn mixed into U.S. soybeans".

In the same year, French scientists confirmed that a genetically modified corn produced by the world's largest seed company, Monsanto in the United States, is toxic to the human liver and kidneys.

In the same year, American scientists also confirmed that the immune system of mice fed genetically modified corn for a long time can be damaged, and the results were published in the journal Agricultural and Food Chemistry in the same year.

Transgenic is the artificial introduction of foreign genes to change the quality of the species and achieve the purpose of improvement. Genetically modified food has brought great help to solve the food crisis of mankind, but its harm to human beings is still being observed. Theoretically, genetically modified foods are harmful to humans, but in reality, they have not been observed to be harmful to humans.

It is not a generalization for the base food, which can neither be completely affirmed, said to be absolutely harmless, nor can it be completely denied. Therefore, it is necessary to promote it cautiously, experiment repeatedly, and consider not only specific crops, but also specific groups of people and specific physiques. You can't test the majority.

I am a little disgusted with genetically modified food, and I always feel that eating genetically modified things is not steady! It is difficult to distinguish between genetically modified and non-genetically modified foods from real and fake, which is really helpless! But people have to eat to live!

Genetically modified food is a kind of achievement of the development of science and technology in modern society, and the world's advantages and disadvantages of genetically modified food, whether it is harmful to the human body or not, and there is no positive argument in the scientific community to confirm whether genetically modified food is harmful or harmless.

Actually, I want the landlord to help me popularize science, what is genetically modified corn? What genes did it transfer? Has it been detected that some genetically modified corn is transgenic and endangers the health of the animals?

If you know too much, you won't dare to say it then, and it's better to know less.

Don't be overly afraid, people eat a lot of different genetic products from humans every day, but they don't change their genetic structure.

It's very simple, let the people from the Ministry of Agriculture and those who are engaged in scientific research in this area eat, as long as they and their families eat, we can eat.

All strange vegetables! Or everything that has changed its original appearance is better not to buy and eat! At present, the goods are circulating all over the world**! It's better to be on guard!

Staple foods that increase protein content and reduce sugar content.

Support the application of genetically modified technology, and eat it every day.

So many people are averse to genetically modified things, why promote it? Demand determines the market, you can prepare a small amount, mark it clearly, and buy what you are willing to buy, remember not to fool consumers, please respect the right to buy goods.

Genetically modified data introductionThere are two corn varieties after transgenic Note: Can male sterility tell the masses what it means?

Who introduced genetically modified poisoned food to China? And who is promoting genetically modified poison food in China? What is its real purpose?

Terrible, what will the Chinese eat in the future.

Previously, Shi Yanquan, deputy director of the Department of Science and Education of the Ministry of Agriculture, said in a guest on China's "China Interview" that there is no domestic genetically modified rice and corn on the market.

Shi Yanquan said that there are two situations of genetically modified products approved in China, one is for commercial production of genetically modified edible crops, while genetically modified rice and transgenic phytase corn need to be approved by the variety, and almost no circulation in the market.

Another situation is that China is used to import and process raw materials of genetically modified agricultural products, including soybeans, corn, rape, they will enter the production process, the most is genetically modified soybeans, at present, China issued a total of 5 genetically modified soybean varieties and 13 genetically modified corn varieties import safety certificates, approved application and imported genetically modified organisms are strictly evaluated in terms of environmental safety and food safety. The safety evaluation shows that these GMOs and non-GMOs that are approved for application and import have the same safety and can be eaten with confidence.

Therefore, there is no genetically modified corn in the Chinese market, but there are processed foods produced from genetically modified corn as raw materials into the market, which can be purchased and eaten with confidence.

The advantage of genetically modified corn is through modern transgenic technology engineering, change the original genetic characteristics, breed high-quality, high-yield, multi-resistant new varieties, traditional corn insect resistance is very weak, some pests such as corn borer can lead to corn yield reduction or no harvest, in addition to pests, the bacteria on the pests and the trauma of corn fruits will produce a corn ear rot, which is the rot and mildew caused by fungi. These are the main culprits that have led to a large reduction in corn production. No one wants to encounter bugs or rot while eating corn.

Genetically modified corn improves resistance by changing its own genes, so for some specific pests, genetically modified corn is deadly, but for humans, it will not hurt to eat as much as you want. The yield of corn has a great impact on industry and animal husbandry. Therefore, it is necessary for us to develop genetically modified corn.

Genetically modified corn is insect and herbicide resistant.

Insect resistance can reduce the use of pesticides due to disease reduction.

The traditional corn is not resistant to herbicides, and the weeds and corn die together when the herbicides are sprinkled, so farmers need to hoe themselves to weed one by one, and the labor is heavy. Herbicide-resistant corn can be sprinkled with herbicides to eliminate weeds in the field, while corn is not affected, significantly reducing the amount of labor.

Yes, yes, yes, no.

Genetically modified corn is the use of modern molecular biotechnology to introduce the genes of plants that are very distant and useful into the genetic material of corn that needs to be improved, and make its offspring reflect the corn with stable genetic traits that people are pursuing. Genetically modified technology is the core technology for the production of transgenic corn, which is the use of DNA recombination technology to transfer foreign genes into recipient organisms, so that they can produce directional and stable genetic changes, that is, new recipient organisms obtain new traits.

Since the advent of genetically modified corn, although some of its improved traits can meet people's requirements, its safety is still controversial. Scientists and countries** also have different attitudes towards genetically modified corn. [1]

As of December 19, Shenzhen, Fujian, Shandong, Guangdong, Zhejiang, Xiamen and other port inspection and quarantine agencies have successively detected MIR162 genetically modified components that have not been approved by China's Ministry of Agriculture from 12 batches of 12 tons of corn exported to China from the United States. The inspection and quarantine agencies at various ports have returned the 12 batches of corn imported from the United States to China in accordance with the law.

Sweet corn is a hybrid variety, in addition, although a large number of genetically modified corn is imported in China, but these corns are used to process feed, and the corn that is usually eaten is planted domestically, and there is no approval for the cultivation of genetically modified corn in China.

It's not clear, there are non-GMO.
