Genetically modified (GM) foods are hazardous in the following ways:
1, GM foods have pesticides: because GM seeds are generally resistant to pests, which makes the weeds around them also resistant to pests, so we need to use more pesticides to kill the weeds, and therefore GM foods also go through a lot of pesticides, and in the end these foods are eaten by us.
2. GM foods have unknown toxins: GM seeds and foods may contain unknown toxins, which may also cause allergies. 37 people died from the production of the L-tryptophan additive in 1989, where the bacteria in the additive underwent genetic recombination, which resulted in the creation of new toxic amino acids in the additive. Many food organisms themselves produce large amounts of toxic substances and nutritional factors such as protein inhibitors, hemolytic thrombi, and neurotoxins to resist invasion by pathogenic bacteria and pests. The level of toxins in existing foods does not necessarily cause toxic effects, but genetically modified foods may produce a wide range of toxicity.
3, Increased phytoestrogen content in GM foods: The use of glyphosate improves herbicide resistance in crops, but also leads to increased phytoestrogen content in crops. Phytoestrogens are harmful to all mammals, including humans, and children are highly susceptible to high levels of phytoestrogens, which can be dangerous and pose long-term health risks.
Genetically modified (GM) food is the use of modern molecular biotechnology, the transfer of genes from certain organisms to other species, modifying the genetic material of organisms, so that their shape, nutritional quality, consumer quality and other aspects of the transformation of the goal of people's needs. [1] That is to say, genetically modified organisms as direct food or as raw materials for the production of food processing is "genetically modified food".
From the world's earliest genetically modified crops were born in 1983, to the United States Monsanto company genetically modified food development of delayed ripening and preservation of genetically modified tomatoes approved in the United States in 1994 on the market until the research and development of genetically modified food development has been rapid development of the product varieties and production has increased exponentially, genetically modified as a new biotechnology, its immaturity and uncertainty, so that the safety of genetically modified food has become a focus of attention. The safety of genetically modified foods has become a focus of attention.
As of 2013, countries engaged in the research and development of genetically modified (GM) animals and plants have formulated corresponding policies and regulations to ensure the safety of GM food. For example, the U.S. has established a sound management organization engaged in food safety and environmental testing and strict safety standards for the research, development, testing, and production of genetically modified (GM) animals and plants to carry out rigorous management and effective control of each GM organism in the release of the environmental testing and the transfer of the production of commodities before the safety of the organisms themselves, as well as the production process of the safety of the production process, the risk of the assessment and review, through the relevant standards before being approved. relevant standards before approval is granted.
In order to unify the standards for evaluating the safety of genetically modified foods, the International Food Regulations Commission (IFRC) under the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) has also decided to formulate an international safety standard for genetically modified foods. In China, the former National Science and Technology Commission (NSTC) first formulated the Measures for the Safety Administration of Genetic Engineering, and then the Ministry of Agriculture (MOA) formulated the Measures for the Implementation of the Safety Administration of Agricultural Genetic Engineering on the basis of the Measures, and at the same time, set up the Committee on Safety of Agricultural Bio-engineering to be responsible for the approval of the safety of the nation's agricultural bio-genetic engineering bodies.
