Transgenic corn is a kind of corn with stable genetic traits that people pursue by introducing the genes of distant and useful plants into the corn genetic material that needs to be improved by using modern molecular biotechnology. Generally speaking, transgenic corn is the result of concentrating the advantages of other corn on one kind of corn.

Countries all over the world have reported examples of the harm of genetically modified corn:

As early as 1 year and as early as 1999, JohnLosey, a researcher at Cornell University in the United States, also published a report in the British magazine Nature, feeding butterflies with leaves coated with Bt transgenic corn pollen, resulting in 44% larvae death.

2. In Brazil, the planting of genetically modified crops began many years ago, which caused a large number of Brazilian women to be infertile, and the infertility rate reached 44%.

In 3.200 1 year, "Mexican corn gene pollution incident" occurred, and in 2002, "genetically modified corn mixed with American soybeans incident" also appeared.

In 2007, French scientists confirmed that a genetically modified corn produced by Monsanto, the world's largest seed company, was toxic to human liver and kidney.

5. In 2008, American scientists also confirmed that the immune system of mice fed with genetically modified corn for a long time would be damaged, and the research results were published in the Journal of Agricultural and Food Chemistry in the same year. ?

Extended data:

The so-called genetically modified food is to transfer one or more foreign genes into a specific organism through genetic engineering technology, and make it effectively express the corresponding products (polypeptide or protein). This process is called transgene. The food produced by genetically modified organisms is genetically modified food.

From the birth of the earliest transgenic crop (tobacco) in the world in 1983 to the approval of the extended-ripening and fresh-keeping transgenic tomato developed by Monsanto in the United States in 1994, the research and development of genetically modified food developed rapidly, and the variety and output of products also increased exponentially. As a new biotechnology means, the immaturity and uncertainty of transgenic technology make the safety of genetically modified food become the focus of attention.

In the international community, as of 20 10, the commercialization of wheat staple food in the United States has not been promoted, Japan banned the import of genetically modified rice from the United States, and India stopped the commercialization of genetically modified eggplant.
