The objective of the study was to determine qualitatively by validated Real Time PCR method the occurrence of genetically modified maize and soybean in commercial food products from the Greek market. 70 independent samples were collected, including products from different categories (i.e. cereal based, biscuits and snacks) which declared either corn or soybean on the labelling. The result of the study indicated that 37.1% of maize and soy products (n=70) displayed in the Greek market have detectable levels of genetically modified maize or soy. These products were identified by specific primers and included common GMΟ detection primers for 35S and NOS terminator. Adequate repeatability and reproducibility was demonstrated for the applied Real Time PCR method, as evaluated by intra- and inter-laboratory tests.

The use of genetically modified organisms (GMO) in food is a highly public and controversial issue. We have used an enzyme-linked immunosorbent assay (ELISA) to detect the genetically modified protein 5-enol-pyruvylshikimate-3-phosphate (EPSP) synthase within soy-containing food products from the grocery store. We found that EPSP synthase is detectable in 3 out of 5 food products tested. Of specific interest, we found contamination levels of EPSP synthase (0.36%) in Heinz' Pablum Soya Cereal, which is currently deemed to be free of genetic modifications by the company as well as by Greenpeace Canada. These results demonstrate that genetically modified organisms are present in foods commonly available for human consumption and that the widespread use of this technology may make it difficult to ensure that any given product is free of all traces of genetically modified protein.

Abstract Background: Genetically modified (GM) foods could be a promising option to reduce the dependence of the agri-food system on conventional means of crop improvement. However, the safety of GM food remains a concern, in addition to the perceived and real risks to environment. The opinion about scientific evidence among researchers, policymakers and government regulators on promotion of GM foods for consumers differ. This study presents the trends emerging from research outputs on consumer perception and preference for GM foods and policy prescriptions for enabling the consumption. Scope and Approach: The study mainly focused on (1) exploring the publication trends, geographic focus of research and a comprehensive review on the consumers' perception of and preference to GM foods, (2) identifying research hotspots and emerging genetically modified organisms (GMO) research themes, (3) assessing the integrated nature of GMO research, and (4) suggesting policy prescriptions on challenges and way forward. Bibliometric analyses have been performed using the Web of Science (WOS) database sourcing literature from 1981 to 2021 and analyzed the final sample of 543 publications using BibExcel and VOSviewer visualization software tools. The search strategy utilized the topic basis search of phrases related to GM food preference and perception. Key Findings and Conclusions: The search query retrieving 543 journal articles showed an increasing trend in publications on consumer's response towards GM foods. Thematic analysis revealed a strong interlinkage of GMOs research with 'agriculture' and 'food science technology'. Consumers' positive response is largely influenced by the decision of the governments to ban or approve the GM crops cultivation. Similarly, the public support increases when the potential benefits of the technology are well articulated, consumption increases with a price discount, people's trust on the government and belief in science increases with a positive influence by the media. Mapping of the retrieved articles showed the top four recurrent keywords: GMOs, biotechnology, attitudes and acceptance. Europe and the USA are the first region and country, respectively, in terms of the number of active institutions per research output, per capita GDP publication and citations per article. The National Natural Science Foundation of China, followed by the National University of Malaysia are the top fundraisers for research on GM food consumption, perceptions and attitudes. Although research outputs on GM food consumer's acceptance and preferences are increasing, a majority of publications came from developed nations. Thus, intensive research is yet to be carried out in developing countries to produce a genetically modified food product with superior properties and substantial equivalence with no significant side-effects. We suggest research-, agri-food industries-, and society-oriented policies needed to be implemented by the stakeholders to ensure the safety of GM food products, encourage consumer-based studies, and increase public awareness towards these food products.

In this paper, we investigated educated millennials’ evaluation of credence attributes in food products containing genetically modified organisms (GMO products). Our goal is to assess whether beliefs about GMO products are determined by scientific knowledge alone or if they are affected by other factors such as trust in information providers and use of social media. The focus on millennials is motivated by the increasing relevance of this social group in the public debate and by their extensive use of social media. We surveyed a sample of 215 Italian college students, confronting them with questions about safety, environmental impact and ethical issues in GMO product consumption. Using an ordered probit regression model, we found that educated millennials build their beliefs using a mix of scientific knowledge and trust in information providers. The role of the two drivers depended on the issue considered. Scientific knowledge drove beliefs in health claims, while trust in information providers was a driving factor in almost all claims. After controlling for trust effects, we did not find evidence of impact of confidence in the reliability of traditional and social media on beliefs. This result contradicts previous literature.
