In this blog post, I aim to re-examine the heightened concerns about food safety following the Fukushima disaster and the resulting worries regarding GMOs (genetically modified organisms), summarise the arguments for and against, and present my own position on whether GMOs can be trusted.

The Issue and Background

Following the Fukushima nuclear accident, fears of radioactive contamination have made people far more sensitive to the origin and safety of food. As a result, consumers have begun to scrutinise where food comes from, how it is produced, and even whether it has been genetically modified, leading to growing doubts about the safety of food on the market. In particular, the notion of ‘artificially altering genes’ instinctively triggers anxiety among ordinary consumers who lack specialist knowledge of biotechnology.
Amidst this climate, GMOs have become a source of concern for many people. Whilst some studies have reported that consumers express strong scepticism towards GMOs and tend to avoid purchasing them, these surveys vary significantly depending on the timing and sample group, making it difficult to generalise public opinion based on simple figures alone. Therefore, this article aims to examine the causes of consumer anxiety, the scientific evidence, and policy responses.

Definition and Technical Understanding of GMOs

GMOs refer to genetically modified agricultural products, generally denoting crops to which genetic engineering techniques have been applied to enhance productivity or improve convenience in distribution and processing. This involves introducing or regulating specific genes to confer traits that are difficult to achieve through traditional breeding methods. Food and drug safety authorities sometimes refer to these as ‘recombinant foods’, and the core objective is to modify genes to confer useful properties such as resistance to pests and diseases, herbicide tolerance, and improved shelf life.
Genetic engineering technology involves extracting useful genes from a specific organism and inserting them into another. This process is designed with the intention of clearly identifying the target gene to confer only the desired traits, and technically involves the use of molecular biological tools alongside strict quality control procedures. In this respect, it is important to understand that, contrary to the impression of mere ‘artificial intervention’, modern biotechnology aims for highly precise manipulation.

Arguments in favour: Practicality and economic viability

I am in favour of the use of GMO technology. Firstly, there are already examples in various regions where GMO technology has increased agricultural productivity and contributed to agricultural stability. Cases have been reported where introducing resistance genes into specific crops has reduced damage from pests and diseases, thereby improving harvest stability and quality; this has had a positive impact on the economic recovery of the region and farmers’ incomes.
Secondly, from an economic perspective, GMOs can lead to reductions in management costs. Traits such as disease and pest resistance, or herbicide tolerance, reduce the use of pesticides and labour input, thereby lowering maintenance costs and contributing to an overall reduction in production costs. These cost savings can lead to improved profitability for farmers and ensure the stability of the food supply.

Rebuttal of opposing arguments: Safety, environmental and naturalness debates

The core argument of opponents is the issue of safety. Concerns that genetically modified foods may have adverse effects on human health are fundamentally valid sentiments. However, comprehensive reviews by the scientific community have predominantly concluded that, to date, most GMO crops distributed after undergoing rigorous safety assessments have not been proven to pose clear harm to humans or animals. The fact that no significant harm has been repeatedly found in animal experiments and toxicological assessments serves as important evidence. Furthermore, some studies with inadequate experimental design and statistical analysis have faced strong criticism within the academic community, and their shortcomings have been highlighted through replication studies.
From an environmental perspective, there are also concerns regarding gene flow and the reduction of biodiversity. These concerns may be valid depending on the circumstances, and therefore management, monitoring and regulation are crucial. On the other hand, in some cases, the introduction of genetically modified crops has had a positive effect by reducing pesticide use, thereby alleviating the burden on soil and ecosystems. In conclusion, as environmental impacts vary depending on the type of crop, cultivation methods and the characteristics of the local ecosystem, case-by-case assessments and supplementary measures are required rather than a blanket conclusion.
Finally, regarding the ethical and philosophical criticism that it ‘goes against the natural order’, it must be noted that genetic modification technology is not an entirely new phenomenon. Humans have long improved crops through breeding and cross-pollination, and modern genetic engineering enables more precise and predictable changes as an extension of this process. Of course, social debate regarding the ethical use of the technology and its long-term impacts must continue, and transparent information provision and participatory decision-making are essential in this process.

Policy Recommendations and Conclusion

I believe that, based on a comprehensive review of the scientific evidence and practical cases to date, GM technology is a technique worthy of full utilisation. However, to secure public trust, this must be accompanied by the strengthening of regulatory frameworks, transparent disclosure of information, and independent safety assessments. If legal and institutional mechanisms are improved to address public concerns, and communication grounded in scientific evidence is established, the social acceptance of GM technology can be enhanced.
Finally, it is clear what can be done institutionally for those who lack confidence in GMO technology. Whilst regulatory legislation must be revised and safety measures strengthened, relevant agencies must continue their efforts to provide education and information aimed at improving public perception. Through this, it is hoped that GMOs will continue to contribute to agricultural society and develop in a direction that produces safer food.
