Genetic engineering and the food derived from genetically modified crops (GMCs) have been the center of debate worldwide, as has occurred historically with the advent of new technologies. Questions are derived from the potential impact of GMCs to the environment and the safety of the products to the consumers. In relation to the first inquiry, practice has been oriented to a case-by-case-study, according to the own characteristics of the GMC, in order to minimize its impact in the environment. Scientific studies in diverse latitudes of the world have demonstrated that GMCs in the market showed no adverse effects related to this issue. In relation to food derived from the GMCs, rigorous evaluation protocols have been developed and approved by FAO and WHO to guarantee the innocuousness of these products. Up to the moment, no contraindications for human health have been pointed out for the products that are available today in the market. In the particular case of Costa Rica, the country has established since the 90s a regulatory biosafety framework for the management of the GMCs, safeguarding the biodiversity of the country and the health of consumers. At the same time the country has made significant public and private investments in the field that allowed the country to obtain a leading position in biosafety in the region and genetic engineering research at national research centers. Any attempt to restrict or prohibit these activities in the country, will put in risk the previously described investment, will affect the generation of new knowledge for decision making and the leadership in the field, preventing the benefits derived from this promising technology.
基因工程以及源自转基因作物(GMC)的食品一直是全球争论的焦点,正如历史上新技术出现时所发生的那样。问题源于转基因作物对环境的潜在影响以及产品对消费者的安全性。关于第一个问题,实践已转向根据转基因作物自身的特性进行逐案研究,以尽量减少其对环境的影响。世界不同地区的科学研究表明,市场上的转基因作物未显示出与此问题相关的不利影响。关于源自转基因作物的食品,粮农组织和世卫组织已制定并批准了严格的评估方案,以确保这些产品无害。到目前为止,市场上现有的产品尚未发现对人类健康有任何禁忌。就哥斯达黎加的具体情况而言,该国自20世纪90年代以来就建立了一个转基因作物管理的生物安全监管框架,以保护该国的生物多样性和消费者的健康。与此同时,该国在该领域进行了大量的公共和私人投资,使该国在该地区的生物安全以及国家研究中心的基因工程研究方面占据了领先地位。在该国任何限制或禁止这些活动的企图,都将使上述投资面临风险,将影响用于决策的新知识的产生以及该领域的领先地位,从而阻碍从这项有前途的技术中获得的益处。
