The Food Safety and Standards Authority of India (FSSAI) have not approved any genetically modified (GM) food products to be manufactured, distributed, sold/or imported in the country. Many countries across the globe are legally approved to cultivate GM crops like soybean, maize, canola, cotton seeds, etc. Many people living in urban India nowadays prefer to purchase imported food products. As a result, an increasing number of food items (without GM labels) are being imported in India. Nevertheless, these products are also easily available for buyers online. Thus, it is important to understand whether these imported food items available in the Indian market are GMO-free. The objective of this study is to check the availability of GM food products in raw and processed forms in the Indian local market through the use of conventional Polymerase Chain Reaction (PCR). The study is designed to screen for the presence of regulatory genes (35S promoter and NOS terminator) which are the most common sequences found in transgenic food products. Using the cetyl trimethyl ammonium bromide (CTAB) method, DNA was extracted from 12 food samples commercially available in the Indian market (locally and online) followed by PCR to detect the presence of GM DNA using HIMEDIA’S MBPCR055 GMO detection kit. Overall, 16.66% of the total samples were tested positive for GM DNA. Of the imported food items, 33.33% were tested positive. Products that were manufactured in the US and Netherlands were tested positive for GMOs. Their main ingredients were also soy and corn. Samples manufactured in India were GMO negative.

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.

Informational Reinforcement

Today, the demand for quality food is increasing and genetically modified food has become part of the Asian diet. Based on the potential of GM food products and Malaysia’s plan to expand its biotechnology industry, the market for GMO will surge if Malaysian consumers are well-informed on the advantages of GM food products. Therefore, this study proposed nine hypothesis to understand Malaysia consumers’ preference for switch from conventional food to genetically modified food. The result indicates that utilitarian, aversive and informational reinforcement will increase consumers’ preference towards genetic modified food if they are aware that genetically modified food brings more advantages than disadvantages to human being. In addition, result shows that consumer who switch will have higher intention to recommend GMO food to others and willing to pay more for GMO food.

Using Data

Purpose Genetically modified (GM) food consumption causes discussions among consumers. So, the present research is aimed to study the hypothetical consumption of a particular kind of GM food products in Italy, which are from the second generation. Design/methodology/approach This research suggests both information about this particular kind of consumption and factors that determine their purchase through statistical techniques for testing and estimating causal relations, using data derived from carrying out sample surveys. Above all, the factor analysis and the cluster analysis are used for the aim of the study. Findings The proposed study shows that transgenic consumption is especially linked to knowledge and impact on health, but also the possibilities that they are able to give when special properties, that can be added to food products, are considered. Moreover, it was possible to identify three kinds of consumer-of-food under investigation: the agree one (37 per cent of the sample), with highest level of perceived expectation and willingness to pay; the half-agree one (27 per cent), with lowest level of desire but highest level of satisfaction; and the disagree one (36 per cent), with negative relationship with all of the factors, particularly with the perceived expectation. Originality/value The research considers a topic not addressed in details; moreover, it is also based on the author's own previous research and is its natural continuation and development, but also important for future researches.

In Japan, a large U.S. export market, there has been growing public opposition against genetically modified (GM) foods. Using a dichotomous choice contingent valuation method, findings show the discount needed for Japanese Seikyou consumers to purchase GM food products is positively affected (i.e., a greater discount is required) by higher levels of self-reported risk perceptions toward GM food, higher levels of concern about food safety and the environment, higher self-reported knowledge about biotechnology, education levels, and income. Interestingly, gender does not significantly affect the discount needed for GM food. Further, it can be inferred from the results that a transformation of Japanese consumers’ perceptions and attitudes is needed for GM food products to successfully enter the Japanese market.

Genetic engineering and Biotechnology are the promising discipline of study in the global market. Genetic alterations are carried in indigenous species with increased sophisticated strategies and techniques to yield hybrid varieties. In Food biotechnology, Genetically Modified Foods have become new, revolutionary and emerging concepts to fulfil the food crisis encountered by developing countries such as India. Genetically Modified foods are produced from the native species by genetically modifying the genes and the modifications are created in accordance to the requirement of the end users. Different indigenous ancient species have been merged to produce new hybrid varieties that are healthy and offers many benefits. Many GM food products are accessible in the markets like grain hemp, honey, tomato, sweet potato, sweet corn, meat, essential oils etc. Developed countries possess a wide understanding about GM foods, its labelling and traceability. However in Developing countries like India, the individuals are unaware about GM foods and they ingest the food without knowing that it is genetically altered. Since awareness about GM foods are less amongst the population, Government need to take necessary measures to analyse about impacts caused by GM foods on human population and implement legislations in order to label the GM food items. As students are definitely the asset and the back bone in developing country they must be conscious of what they consume. The current study is in order to know about students’ awareness on genetically modified food products and their perception towards GM foods. The Sample involves 163 college students of arts and science in and around Chennai metropolis.

The Impact

We experimentally test whether expert organizations on social media can correct misperceptions of the scientific consensus on the safety of genetically modified (GM) food for human consumption, as well as what role social media cues, in the form of “likes,” play in that process. We find expert organizations highlighting scientific consensus on GM food safety reduces consensus misperceptions among the public, leading to lower GM misperceptions and boosting related consumption behaviors in line with the gateway belief model. Expert organizations’ credibility may increase as a result of correction, but popularity cues do not seem to affect misperceptions or credibility.

Focusing on debunking misinformation about genetically modified (GM) food safety in a social media context, this study examines whether source cues and social endorsement cues interact with individuals’ preexisting beliefs about GM food safety in influencing misinformation correction effectiveness. Using an experimental design, this study finds that providing corrective messages can effectively counteract the influence of misinformation, especially when the message is from an expert source and receives high social endorsements. Participants evaluate misinformation and corrective messages in a biased way that confirms their preexisting beliefs about GM food safety. However, their initial misperceptions can be reduced when receiving corrective messages.

Purpose The purpose of this paper is to investigate the role of perceived food quality and consumer ethnocentrism and potential trade-offs between these two concepts in Russian consumers’ food purchase decisions after the implementation of the Russian import ban. Design/methodology/approach Survey data were collected via in-person interviews in the City of Perm, which is one of the largest and most industrial cities in Russia. A double-bounded dichotomous-choice contingent valuation model is utilized to estimate willingness to pay (WTP) and to analyze factors that affect consumers’ choice. Findings The results suggest that most respondents do not consider domestically produced cheese as a risky product in terms of food safety but simply of lower quality than imported cheese. However, the average respondent’s WTP discount for domestic cheese compared to imported cheese is 8 percent, which is relatively small. This corresponds to participants’ opinion that buying domestic cheese is the right thing to do since it supports Russian farmers and producers. The results indicate further that with increasing education and income levels, individuals are less likely to prefer domestically produced cheese for either economic or quality reasons. This effect is stronger for the quality preference. Research limitations/implications The results indicate that if the Russian government aims at expanding the domestic food market further, more attention needs to be paid to ensuring the quality of domestic food products in order to increase consumer acceptance and WTP. Originality/value This is the first study providing empirical evidence on Russian consumers’ attitudes and perceptions of domestically vs imported food products after the implementation of the Russian import ban, which can be considered as an external policy shock.

This paper reports on one aspect of qualitative research on public understandings of food risks, focusing on lay understandings of genetically modified (GM) food in a UK context. A range of theoretical, conceptual, and empirical literature on food, risk, and the public understanding of science are reviewed. The fieldwork methods are outlined and empirical data from a range of lay groups are presented. Major themes include: varying “technical” knowledge of science, the relationship between knowledge and acceptance of genetic modification, the uncertainty of scientific knowledge, genetic modification as inappropriate scientific intervention in “nature,” the acceptability of animal and human applications of genetic modification, the appropriate boundaries of scientific innovation, the necessity for GM foods, the uncertainty of risks in GM food, fatalism about avoiding risks, and trust in “experts” to manage potential risks in GM food. Key discussion points relating to a sociological understanding of public attitudes to GM food are raised and some policy implications are highlighted.
