Abstract This paper presents the results of a choice experiment that encompassed the labelling options outlined in the Australian and New Zealand government's recently finalized mandatory labelling system for genetically modified foods (GMF's) and foods that contain genetically modified ingredients. The labelling scheme is to be implemented across both countries from December 2001 onwards. Results suggest difficulties ahead for manufacturers and growers of GM labelled product if there is an ample supply of GM-free labelled alternatives. It is also likely that manufacturers and growers of GM-free product will realize greater levels of demand over non-labelled and GM product even when these alternatives are substantially cheaper. 相似文献

转基因食品强制标识制度在世贸组织框架内的法律分析 总被引:1,自引:0,他引:1
鉴于转基因食品可能存在不确定的风险,许多国家都要求对转基因食品进行强制标识。由于欧盟自1998年以来暂停批准转基因农产品在欧盟市场的准入申请,2003年5月,美国、加拿大和阿根廷在世贸组织提起针对欧共体的申诉。在该案的审理过程中,欧盟对转基因食品的强制标识制度也成为一个争议的问题,这给中国政府敲响了警钟。在中国,目前有农业部和卫生部的两个相关管理办法。本文根据世贸组织的相关规则,包括《实施卫生与植物卫生措施协定》、《技术性贸易壁垒协定》以及关贸总协定1994第20条,从实体和程序上对我国现行规定的合法性进行了具体分析,并提出了相应建议,以期为政府相关部门的决策提供参考。 相似文献

ABSTRACT This study outlines the controversy surrounding genetically modified organisms (GMOs) and how it impacts North American based food service companies' marketing policies. Recent developments have made foods derived from GMOs a strategic marketing challenge for food service franchise and chain operations. Headlines such as “Why McDonalds Pulled Frankenfries from Menus” have unwittingly put restaurants on the frontline of the battle over foods made from GMOs (Martin, 2000). A survey method was used to explore food service operations' views regarding consumer acceptance of GMOs, right to know issues (labeling) and the benefits of GMOs, as well as food service companies' strategic response to this emerging technology. Findings indicate that food service establishments were generally concerned about customer opinions and tend to prefer government mandated labeling of GMOs. They also tend to feel that GMOs offer potential benefits to their industry and that customer concerns may fade over time. 相似文献

随着经济社会的快速发展和科学技术的日新月异,以提升人民生活水平为目的的转基因食品应运而生。转基因食品在我国的发展时间并不长,但却得到了极大程度的促进与发展,对于其发展的影响,存在着毁誉参半的尴尬境地。但不能抹杀的是转基因食品的确具有明显的优势,为社会的发展提供了推动力。一方面,转基因食品具有节约成本、提升经济效益和丰富生物产品多样化的优点。但从另一方面来看,转基因食品也具有很大的安全隐患,对生态环境、食用人体的健康,甚至物种自身的发展都存在很大的不良影响。基于此,研究关于转基因食品安全性评价,以期进一步推动转基因食品相关技术的发展,为社会和人类的进一步发展作出贡献。 相似文献

This study examines the perceptions and attitudes of Singaporean residents who attended the first public lecture on genetically modified (GM) food in the country. Scales were developed for the underlying consumer concerns, and their relationship with one another and with demographic variables were examined. Slightly more than half of those who attended the talk (n= 417) indicated that they were worried about GM foods and 86 percent agreed or strongly agreed that GM foods should be labeled. Issues relating to health, ethics, and perceived benefits were the major underlying concerns. These were related to several demographic variables and also to perceived knowledge about biotechnology. Women were more concerned about the ethical and health aspects compared to men. Those with post‐graduate education were the least concerned about health and ethical issues and more likely to buy GM foods if consumer benefits are shown. Married respondents were less concerned about health issues compared to single ones. Also, those with children under fifteen years of age were less concerned about health issues compared to others and more likely to buy GM foods if consumer benefits are shown. Respondents subscribing to the Hindu religion were more likely than others to buy GM foods If benefits are shown. Also, those who considered themselves vegetarians were more concerned about the ethical aspects of GM foods compared to others. 相似文献

A study was carried out in Germany in order to assess consumers' acceptance of genetically modified (GM) foods with health benefits (bread, yohurt and eggs). Acceptability of GM foods increases when its source does not involve animal products such as eggs. Three factors have been identified as direct antecedents of the acceptance of GM foods: respondents' attitude towards biotechnology, health consciousness, and time pressure, being the first one the most salient one. Price consciousness has an indirect positive impact (mediated by health consciousness) upon acceptance of GM products. Males were more likely to accept GM foods with health benefits. 相似文献

A purchasing experiment in which genetically modified and conventional fries were offered for sale at mobile fast food stands in Germany was conducted to identify factors influencing the willingness of consumers to purchase genetically modified fries. In total, 331 purchasing decisions were made: 56.5% decided to purchase conventional fries, 22.4% genetically modified fries, and 21.1% no preference. A logistic regression model analyzing questionnaires found that worry about pesticides, frequency of organic food purchases, the acceptability of genetically modified foods with environmental benefits, and perceptions of health risks from genetically modified foods significantly impact the willingness to purchase genetically modified fries. 相似文献

Arguably genetic modification is one of the most important technological change seen to date. Its effects on both human health and the environment are both profound and controversial. In particular consumers, mainly in the EU, have concerns regarding the long term effects of consuming genetically modified foods on their health. They are also concerned regarding the effect that genetically modified organisms will have on bio‐diversity and choice in the long run. Differing regulatory regimes towards genetically modified goods in the US and EU could lead to damaging trade conflicts. Current agreements covering trade in foods such as the SPS and TBT allow a way of diffusing conflicts. The primary aim of these agreements is, however, to prevent governments from protecting domestic producers by applying capricious barriers to foreign competition. This paper sets out to show that rather than modifying these two agreements it would be better to deal with new issues surrounding consumer preferences explicitly by negotiating a new international agreement. 相似文献

New technologies are hitting the marketplace every day. In trying to make sense of these new technologies, consumers perceive a series of risks and benefits of consumption and use those perceptions to form product judgments. One way for managers to mitigate organizational related risk is to understand how consumers perceive consumption‐related risk. To illustrate this point, the case of genetically modified (GM) food is examined and a series of focus groups is conducted in which participants examined different product labels that either framed the technology as a benefit gained or as a risk avoided. The results indicate that consumers do indeed form very different product evaluations based on how the new technology is framed, but these evaluations vary based on the level of the consumers’ preexisting knowledge. This study provides support for the contention that a better understanding of consumer risk perceptions is an important first step in developing marketing strategies for new technology‐oriented products. 相似文献

Understanding Attitudes Towards Genetically Modified Food: The Role of Values and Attitude Strength 总被引:3,自引:0,他引:3
Summary This study was aimed at gaining a better understanding of the nature of negative attitudes towards genetically modified (GM) food. A sample of 250 students at the University of Tromsø responded to a questionnaire measuring attitudes towards GM food, attitude strength, intention to buy such food, and their personal values. Values and attitude strength proved to be important constructs when explaining the attitudes. A structural model was estimated, confirming that the negative attitudes towards GM food were embedded in universalism and hedonism values, and also predicted behavioural intention to buy such food. Attitude centrality was found to moderate the value-attitude relationship. Central attitudes mediated the relation between values and behavioural intention, while for the less central attitudes there was no relation between values and attitudes. Rather, both were independent predictors of intention. The study showed that some individuals hold weak attitudes and therefore may be more likely to change their attitude than those whose attitude is embedded in values. 相似文献
