RESUMO

Labels are influential signals in the marketplace intended to inform and to eliminate buyer confusion. Despite this, food labels continue to be the subject of debate. None more so than non-GMO (genetically modified organisms) labels. This manuscript provides a timeline of the evolution of GMO labels beginning with the early history of the anti-GMO movement to the current National Bioengineered Food Disclosure Standard in the United States. Using media and market intelligence data collected through Buzzsumo™ and Mintel™, public discourse of GMOs is analyzed in relation to sociopolitical events and the number of new food products with anti-GMO labels, respectively. Policy document and publication data is collected with Overton™ to illustrate the policy landscape for the GMO topic and how it has changed over time. Analysis of the collective data illustrates that while social media and policy engagement around the topic of GMOs has diminished over time, the number of new products with a GMO-free designation continues to grow. While discourse peaked at one point, and has since declined, our results suggest that the legacy of an anti-GMO narrative remains firmly embedded in the social psyche, evidenced by the continuing rise of products with GMO-free designation. Campaigns for GMO food labels to satisfy consumers' right to know were successful and the perceived need for this information now appears to be self-sustaining.

RESUMO

BACKGROUND: Dietitians play a critical role in the public's relationship with food and are often overlooked as an important stakeholder group in the general debate about sustainable food. Genetically modified organisms (GMOs) are one type of modern food source that could contribute to a more sustainable food system. This case study is the first to examine the knowledge, perception and willingness-to-recommend (WTR) genetically modified (GM) foods by dietitians in Europe. METHODS: An online survey was addressed to all members of the Flemish Association of Dietitians (Belgium) in 2021, resulting in a sample of 98 valid responses. Multivariate linear regression included sociodemographic, knowledge, and attitudinal factors as the independent variables to explain dietitians' WTR. RESULTS: Flemish dietitians had limited knowledge of GMOs; only about half of the GM questions were answered correctly. Most dietitians (53%-76%) would recommend GMOs with positive effects on human nutrition or sustainability, whereas few dietitians (19%-27%) would recommend other GMO applications. Trust in GMO information sources and perceived GM benefits significantly influenced a positive WTR of GM foods. Predominant negative information about GM foods was significantly associated with dietitians' low trust and WTR such foods. CONCLUSIONS: Countering the predominantly negative portrayal with more neutral and factual information could improve trust, which in turn could positively influence dietitians' perceptions towards GMOs. By further examining the knowledge and perception of dietitians worldwide GMOs and gene-edited products, new insights could be could gathered into the positioning of this underexposed stakeholder group.

RESUMO

Families increasingly raise questions about the use of genetically modified organism (GMO)-containing food products. These products are widely found in the US food supply but originate from a narrow list of crops. Although GMO technology could be used to increase the micronutrient content of foods, this does not occur in the United States; instead, GMO technology has been used to make crops resistant to chemical herbicides. As a result, herbicide use has increased exponentially. The World Health Organization's International Agency on Research for Cancer has determined that glyphosate, an herbicide widely used in producing GMO food crops, is a probable human carcinogen. Measurable quantities of glyphosate are detected in some GMO foods. Families who wish to minimize GMO food products can do so by focusing on a dietary pattern of primarily whole, plant-based foods while minimizing ultra-processed foods. Pediatricians play a vital role in their efforts to minimize fear-based messaging and support families through shared decision-making. Pediatrician awareness of GMO labeling can guide individualized conversations, particularly that non-GMO labeling does not indicate organic status and that increased cost of some non-GMO foods, especially if also organic, may limit this choice for many families.

RESUMO

GM technology has constantly faced opposition in the Philippines. The debate heightened in 2016, when the Supreme Court halted the field testing of Bt eggplant, which triggered a public debate. This ruling was overturned, but GM technology remained in the public consciousness because of the general visibility of science, health, and food security issues. The researcher analyzed opinion columns in major Philippine news outlets from 2016-present to examine candid framings of the GM debate. Through inductive analysis, the researcher found that the debate represents a struggle for control. The crops are not so much monsters as they are hyperbolic jokes that do not meet their promises; they too, represent a foreign industrial invader that can be countered only by contextualized and localized farming. These findings add nuance to our understanding of the GM debate in the Global South.

RESUMO

There is a large literature about consumer acceptance of GM foods dating back almost three decades, but there are fewer studies that investigate how support for specific GM attributes contribute to general support for novel plant technologies. In addition, there is little information on how support has changed over time. Using survey data from 2018 to 2023 in a U.S. State (Vermont) (n = 3101), we analyze changes in support for a variety of GM attributes over time. There are three major findings. First, there is movement toward neutrality in support for various GM attributes, but opposition continues. Second, there is variability in support for different GM attributes. People are most supportive (least opposed) to GM attributes that improve flora (plant health or drought tolerance), and most opposed (least supportive) of attributes that impact fauna (specifically fish). Third, multivariate regression reveals that assessments of individual GM attributes contribute to levels of overall support of the use of GM technologies in agricultural production.

RESUMO

The genetically modified (GM) maize GG2 contains gr79-epsps and gat genes, conferring glyphosate tolerance. The present study aimed to investigate potential effects of maize GG2 in a 90-day subchronic feeding study on Wistar Han RCC rats. Maize grains from GG2 or non-GM maize were incorporated into diets at concentrations of 25% and 50% and administered to Wistar Han RCC rats (n = 10/sex/group) for 90 days. The basal-diet group of rats (n = 10/sex/group) were fed with common commercialized rodent diet. Compared with rats fed with the corresponding non-GM maize and the basal-diet, no biologically relevant differences were observed in rats fed with the maize GG2, according to the results of body weight/gain, feed consumption/utilization, clinical signs, mortality, ophthalmology, clinical pathology (hematology, prothrombin time, urinalysis, serum chemistry), organ weights, and gross and microscopic pathology. Under the conditions of this study, these results indicated that maize GG2 is as safe as the non-GM maize in this 90-day feeding study.

RESUMO

Innovation in agriculture has been essential in improving productivity of crops and forages to support a growing population, improving living standards while contributing toward maintaining environment integrity, human health, and wellbeing through provision of more nutritious, varied, and abundant food sources. A crucial part of that innovation has involved a range of techniques for both expanding and exploiting the genetic potential of plants. However, some techniques used for generating new variation for plant breeders to exploit are deemed higher risk than others despite end products of both processes at times being for all intents and purposes identical for the benefits they provide. As a result, public concerns often triggered by poor communication from innovators, resulting in mistrust and suspicion has, in turn, caused the development of a range of regulatory systems. The logic and motivations for modes of regulation used are reviewed and how the benefits from use of these technologies can be delivered more efficiently and effectively is discussed.

RESUMO

LP007-1 is a variety of insect-resistant and herbicide-tolerant maize containing the modified cry1Ab, cry2Ab, vip3Aa and cp4-epsps genes. The food safety assessment of the maize LP007-1 was conducted in Wistar Han RCC rats by a 90-days feeding study. Maize grains from both LP007-1 or its corresponding non-genetically modified control maize AX808 were incorporated into rodent diets at 25% and 50% concentrations by mass and administered to rats (n = 10/sex/group) for 90 days. A commercialized rodent diet was fed to an additional group as the basal-diet group. The diets of all groups were nutritionally balanced. No biologically relevant differences were observed in rats fed with maize LP007-1 compared to rats fed with AX808 and the basal-diet with respect to body weight/gain, food consumption/utilization, clinical signs, mortality, ophthalmology, clinical pathology (hematology, prothrombin time, activation of partial thrombin time, serum chemistry, urinalysis), organ weights, and gross and microscopic pathology. Considering the circumstances of this study, the results provided evidence that LP007-1 maize did not exhibit toxicity in the 90-day feeding study.

RESUMO

This study analyzes Chinese online science communication and discussion about genetically modified foods (GMFs). Based on data collected from one of the largest Chinese GMFs science popularization website, it utilizes Wodak's discourse analysis to investigate how Chinese genetically modified (GM) scientific discourse is characterized by a range of discursive strategies that construct specific identity of Chinese GM scientists and explore science hegemony underlying Chinese GMFs debates. Findings show that discourse features of Chinese GM scientific discourse is objective as well as emotional, particularly conveying a strong sense of superiority realized by trope, argumentative strategies and intertextuality. The unequal power relationship between scientists and the public as well as Chinese intellectuals' knowledge hegemony could partly explain why those discursive strategies are employed in science communication practices of GMFs debates in Chinese context.

RESUMO

Many African nations place a high priority on enhancing food security and nutrition. However, unfavorable environmental conditions interfere with the achievement of food security in Africa. The production of genetically modified organisms (GMOs) presents intriguing possibilities for improving food security on the continent. In Africa, countries in the same regions have different GMO usage policies and laws. While some nations are updating their laws and policies to allow GMOs, others are still debating whether they are worth the risk. However, there is still little information available regarding the most recent status of GMO applications in Kenya, Tanzania, and Uganda. The current review summarizes the state of GMO applications for enhancing food security in Kenya, Tanzania, and Uganda. Currently, Tanzania and Uganda do not accept GMOs, but Kenya does. This study can assist governments, academics, and policymakers in enhancing GMO acceptance for boosting nutrition and food security in their nations.

RESUMO

The initial compositional analysis of plants plays an important role within the internationally harmonized comparative safety assessment approach for genetically modified plants. Current EFSA guidance prescribes two types of comparison, namely difference tests with regard to a conventional comparator or control, and equivalence tests with regard to a collection of commercial reference varieties. The experience gained so far shows that most of the statistically significant differences between the test and control can be discounted based on the fact that they are still within equivalence limits of reference varieties with a presumed history of safe use. Inclusion of a test variety and reference varieties into field trial design, and of the statistical equivalence test would already suffice for the purpose of finding relevant parameters that warrant further assessment, hence both the inclusion of a conventional counterpart and the performance of difference testing can be omitted. This would also allow for the inclusion of safety testing regimes into plant variety testing VCU (value for cultivation and use) or other, independent variety trials.

RESUMO

Curbing the negative impact of misinformation is typically assumed to require correcting misconceptions. Conceivably, however, bypassing the misinformation through alternate beliefs of opposite implications may reduce the attitudinal impact of the misinformation. Three experiments, one preregistered with a sample representative of the United States population, examined the impact of (a) directly correcting prior misinformation offered in support of restricting Genetically Modified (GM) foods (i.e., the correction strategy) and (b) discussing information in support of GM foods (i.e., the bypassing strategy), compared to a misinformation-only control condition. Findings consistently revealed that bolstering beliefs with opposite implications is just as effective at reducing opposition to GM foods as is correcting misinformation about GM foods. Thus, bypassing should be added to our arsenal of methods to curb the impact of misinformation.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has generated significant economic loss and an unprecedented challenge to people's livelihoods. Using household data collected in November 2020, this study shows that the COVID-19 outbreak has significantly affected consumers' perceptions and consumption of genetically modified (GM) food in China. Their perceptions and purchase intentions have turned more negative, and their actual purchase of GM food has decreased after the COVID-19 outbreak. The study's results also indicate that consumers with more knowledge of genetic modification technology are less likely to change their perceptions of GM food.

RESUMO

Genetic engineering has inserted the crystallin (Cry) gene of Bacillus thuringiensis into the genes of maize to cultivate a variety of transgenic insect-resistant maizes. At present, genetically modified maize with Cry1Ab-ma gene (maize CM8101) was in the stage of safety verification. In this study, a 1-year chronic toxicity test was carried out to evaluate the safety of maize CM8101. Wistar rats were selected for the experiment. Rats were randomly divided into three groups and fed the corresponding diets: genetically modified maize group (CM8101 group), parental maize group (Zheng58 group), and AIN group. Rat serum and urine were collected at the third, sixth, and twelfth months of the experiment, and viscera were collected at the end of the experiment for detection. Metabolomics was used to analyze the metabolites in the serum of rats at the 12th month. While the CM8101 group rats' diets were supplemented with 60% maize CM8101, no obvious poisoning symptoms were found in rats, and no poisoning death occurred. There were no negative effects on body weight, food intake, blood and urine indices, or organ histopathological examination results. Furthermore, metabolomics results revealed that, when compared to group differences, the gender of rats had a more obvious effect on metabolites. The CM8101 group primarily changed linoleic acid metabolism in female rats, while glyceropholipid metabolism was altered in male rats. In rats, consumption of maize CM8101 did not result in significant metabolic dysfunction.

RESUMO

While many types of genetically modified (GM) food have become more available worldwide, the acceptance of GM food continues to be low. To increase this acceptance, various educational interventions have been conducted; however, conflicts remain about the safety and acceptability of GM food among laypeople, experts, and policymakers in several countries. Thus, this study aimed to clarify whether basic biology education influences Japanese people's acceptance of GM food. We examined this idea by comparing individual experiences of high school biology education based on curriculum and proficiency level. We distributed online questionnaires to 1,594 people in Japan; 1,122 valid responses (70.4%) were obtained. Results showed that the acceptance rates of GM vegetables, fish, and meat were 33.6%, 29.0%, and 29.1%, respectively. Comparing the biology knowledge test scores according to different high school biology education levels (i.e., non-learners, basic, and advanced levels) showed no significant differences between the three age groups (20s, 30s, and 40s), which corresponded to different curricula (p = 0.90); however, there were significant differences between the high school biology education levels (p<0.01). Using logistic regression analysis, we then examined the effect of high school biology education on acceptance of GM food. The results showed no significant differences between different high school biology education levels but significantly lower acceptance by the 30s and 40s groups compared with the 20s group (p<0.05). This suggests that basic biology education alone is not sufficient to change people's attitudes toward GM foods. These generational differences suggest factors other than high school biology curriculum affect different generations' acceptance of GM foods. Overall, high school biology education did not directly affect acceptance of GM foods, although those who received a higher level of education had an increased knowledge of GM foods.

RESUMO

Genetically modified (GM) foods have been assumed to be seen through intuitive and affective routes (i.e., affect heuristics) rather than analytical and deliberative routes. We examined the impact of the graphical presentation of benefits derived from GM or conventionally bred foods on the acceptance of these varieties. In the two experiments (n = 266 for study 1 and n = 402 for study 2), no differences emerged in the estimation of farmers' benefits resulting from the introduction of improved varieties by the type of improvement. However, there were statistically significant differences in the magnitude of risk and the degree of acceptance of the improved varieties. Therefore, despite presenting identical benefits as a graphical figure, GM foods were consistently evaluated as providing higher risk and were less frequently accepted than conventionally bred foods. These results suggest that while the graphical presentation of benefits may promote comprehension of some advantages of the introduction of GM varieties, this may not lead to acceptance from the consumer's point of view. Based on the current findings, as well as previous studies on trust in risk managers, we discuss the specific factors that might promote acceptance of GM products.

RESUMO

This study investigated how normative information on Facebook (i.e., the number of Likes on a Facebook post and a refuting comment) influences one's intention to share a rumor post regarding genetically modified foods. The results of an online experiment with 630 Facebook users showed that a high number of Likes increased the intention to share the post through perceived descriptive and injunctive norms of sharing behavior. The number of Likes on the post and a refuting comment interacted to influence perceived injunctive norms about rumor sharing. A comment stating that the post is a rumor increased injunctive norm perceptions about rumor sharing when the number of Likes on the post is low.

RESUMO

Drawing upon the hostile media effect, this study examined how perceived media bias in covering genetically modified (GM) food influences individuals' risk-benefit assessments of it and their food consumption behaviors. The results of a nationally representative survey (N = 1364) showed that individuals seeing media coverage as more biased in favor of GM food perceived it as more hazardous, which was related to a higher proportion of organic food consumption in their diets. In contrast, perceived media coverage as less slanted toward GM food was associated with more benefit perceptions of it, thereby predicting its higher proportion in individuals' diets. More importantly, the indirect effect of perceived media bias on GM food consumption through benefit perceptions was more pronounced among males than females. The findings of this study not only provide empirical evidence of the perceptual and behavioral outcomes of hostile media perceptions, but also offer valuable insights for journalists and education practitioners to improve public understanding of emerging food technologies.

RESUMO

This article investigates Greenpeace's use of science in 'environmental representation' in news articles concerning genetically modified food, and how commenters respond in the associated below the line comments. This article provides an answer through a qualitative data analysis using a discourse analysis of data from 5 UK news organisations, commencing 1 January 2015 until 31 December 2015. The findings reveal the importance of science and scientific evidence in claims-making and 'environmental representation' by Greenpeace in relation to genetically modified foods in news articles. However, below the line commenters reject the idea of scientific evidence being used by Greenpeace. Instead, these commenters claim Greenpeace oppose scientific developments. The article concludes by discussing how this study adds to the understanding of claims-making and 'environmental representation' by Greenpeace with respect to genetically modified foods in news articles, and how the below the line commenters challenge the legitimacy of Greenpeace as an 'environmental representative'.

RESUMO

BACKGROUND: There has been substantial debate surrounding the use of genetically modified foods (GMFs). AIM: The purpose of this study was to describe the content of news articles covering GMFs. METHODS: A search was completed on Google News using the key words "genetically modified foods" and the resulting 100 English-language news articles were analyzed for content. RESULTS: Only 26% of the articles analyzed were from professional or government sources. Among all content categories, definition or explanation of GMFs with a featured product as an example had the highest coverage, being addressed in 74% of the sample. Identification of GMFs from food labels (p = .001), was significantly associated with the source of the article (p > .05). CONCLUSIONS: Opportunities exist for scientists, educators, and health experts to present evidence-based and science-based information, with a balanced emphasis on the risks and benefits of GMFs to help consumers to make well-informed choices.
