The revised GMO corn decree from Mexico to the United States has been the subject of much discussion and debate in recent months. Issued by the Mexican government in late 2021, the decree regulates the import and cultivation of genetically modified corn in Mexico, and is a revision of a previous decree that had been in place since 2013.
One of the most significant changes in the revised decree is the expansion of the list of approved genetically modified corn varieties that can be imported and cultivated in Mexico. The previous decree only allowed for the import and cultivation of three varieties of GM corn, but the revised decree has increased this number to ten. This change has been met with criticism by some, who argue that it could lead to the introduction of more potentially harmful GM crops into the country.
Genetically modified crops, or GM crops, are plants that have had their DNA altered in a laboratory setting using genetic engineering techniques. This allows for the introduction of specific traits or characteristics into the plant, such as resistance to pests or increased crop yield. GM crops have been controversial since their inception, with proponents arguing that they have the potential to increase food security and help feed a growing global population, while critics argue that they may have negative impacts on the environment and human health.
One concern about GM crops is that they may have unintended consequences on the environment. For example, GM crops may interfere with the natural ecosystem, leading to the displacement of native plant and animal species. Additionally, GM crops may cross-pollinate with non-GM crops, leading to the spread of GM traits into the broader ecosystem. This could have significant implications for farmers who rely on non-GM crops, as they may face unintended contamination of their crops by GM varieties.
Another concern about GM crops is their potential impact on human health. While GM crops have been deemed safe for consumption by regulatory agencies in many countries, some studies have suggested that they may have negative impacts on human health. For example, a study published in the journal Environmental Sciences Europe in 2014 found that GM corn was associated with an increased risk of organ damage in rats. However, the findings of this study have been disputed by other researchers, and the safety of GM crops for human consumption is still a subject of ongoing debate.
Given these concerns, it is understandable that the expansion of the list of approved GM corn varieties in the revised GMO corn decree has generated controversy. Some argue that allowing for the import and cultivation of more GM corn varieties could lead to the introduction of potentially harmful GM crops into the country. On the other hand, proponents of the revised decree argue that the expansion of the list of approved GM corn varieties is necessary to meet the demand for GM corn in Mexico, and that the existing regulatory framework is sufficient to ensure the safety of GM crops.
Another controversial aspect of the revised GMO corn decree is the provision that allows for the cultivation of GM corn in designated "experimental zones." These zones are intended to allow for the testing and evaluation of GM corn in a controlled environment, but critics argue that they could lead to the spread of GM crops into the broader ecosystem. Some have raised concerns that the experimental zones could serve as a backdoor for the widespread cultivation of GM crops in Mexico, bypassing the regulatory framework that is in place to ensure the safety of GM crops.
The revised decree has also drawn criticism for its provisions related to labeling and traceability. The decree requires that GM corn be labeled as such, but some argue that the labeling requirements are not strict enough. Additionally, some have raised concerns about the traceability of GM corn, arguing that it is not always clear where GM corn has been grown and how it has been used. This could make it difficult for consumers to make informed decisions about whether or not to purchase and consume GM corn.
