How can you tell which corn is genetically modified?
Nowadays many people are very worried about eating genetically modified food, and corn is one of the four major genetically modified crops, so many people are very worried about whether the corn they buy is genetically modified. At present, which corn is genetically modified?
1. Which corn is genetically modified
In China, the production and sale of seeds of genetically modified corn varieties and their products are not permitted. To sell genetically modified seeds, approval by the State Council is required. Be sure to avoid eating genetically modified corn. Imported canned sweet corn is the most likely to be genetically modified corn, so pay attention to the relevant labeling. Therefore, the domestic corn currently sold on the market is not genetically modified corn, and you can buy and eat it with confidence.
2. The situation of genetically modified corn abroad
In terms of planting scale, genetically modified corn is the second largest genetically modified crop in the world by planted area, after soybeans. Since genetically modified corn was first commercially planted in the United States in 1996, its planted area has grown rapidly, increasing 300-fold in 19 years, and its share among genetically modified crops has also increased by 20%.
In terms of product traits, genetically modified corn includes herbicide-tolerant corn, insect-resistant corn, and stacked-trait genetically modified corn with both traits. As of 2014, the global planted area of genetically modified corn was 54.3 million sq m, accounting for 30% of the total corn planted area. Among this, the planted area of herbicide-tolerant genetically modified corn was about 16.3 million sq m. The genetically modified corn currently planted in five EU countries all shows insect-resistant traits, with a planted area of 116870 sq m. Among them, Spain has the largest planted area, about 107749 sq m.
In terms of countries, the ISAAA 2015 annual genetically modified report shows that a total of 28 countries around the world approved the commercial planting of 29 kinds of genetically modified crops. Among them, the number of countries planting genetically modified corn rose to 17. The United States is the world's largest planter of genetically modified corn. In 2016, the planted area of genetically modified corn reached 35.05 million sq m, accounting for 92% of the total corn sown area in the United States. Among this, 76% was stacked-trait genetically modified corn. In 2003, the Philippines introduced genetically modified insect-resistant corn, becoming the first country in Asia to approve the planting of a genetically modified staple food crop. In 2014, the planted area of genetically modified corn in the Philippines reached 831,000 sq m, and its share of the country's corn had exceeded 25%. In 2015, Vietnam joined the ranks of genetically modified crop planting for the first time, planting stacked-trait genetically modified insect-resistant/herbicide-tolerant corn. By 2020, the global planted area of genetically modified corn is expected to account for 30%-50% of the total crop planted area.
At present, genetically modified corn is almost nonexistent on the domestic market. The corn of all the major varieties seen on the market can be bought and eaten with confidence, and will not be genetically modified food.
