Public attitudes to GM foods. The balancing of risks and gains

In the paper we study the variables influencing attitudes to the use of two biotechnologies related to gene transfer within apples. Using Eurobarometer 73.1 survey data on biotechnology, science and technology, with 15,650 respondents, we study the extent these attitudes are determined by socioeconomic and other variables. We found that attitudes to the risks and gains are determined by socioeconomic variables and also by the individual’s knowledge, scientific background, their parent’s education in science and their religion. Perceptions of naturalness and of environmental impact combined with perceived risks and gains in determining overall approval, proxied by views on whether the technologies should be encouraged, forGMTs. However there are substantial differences in attitudes to transgenesis and cisgenesis.

Organismos geneticamente modificados, seguridad alimentaria y salud: trascediendo la epidemiologia y la salud pública

En las últimas décadas, los cambios en la agricultura y las innovaciones en biotecnología han modificado el panorama de la alimentación del planeta. Desde la década de los cincuenta, la revolución verde ha tenido un impacto dramático a nivel planetario y hoy en día temas como el desarrollo sostenible hacen parte de la agenda política mundial. Los Organismos Genéticamente Modificados han revolucionado la agroindustria y la biotecnología, y en la actualidad los cultivos de este tipo han crecido a un ritmo vertiginoso en varios países. Sin embargo, las promesas de erradicación del hambre y la inocuidad de estas nuevas bondades tecnológicas han creado profunda desconfianza y prevención tanto en la comunidad científica como en el público en general. Muchos abogan por el principio de precaución apelando a la incertidumbre científica dada la escasa evidencia de estudios epidemiológicos que evalúen efectos a largo plazo en la salud pública y al mismo tiempo, crece la polémica frente a un tema complejo de profundo interés general que impacta de manera relevante en diversas áreas del conocimiento.

Transgênicos: avaliação da possível (in)segurança alimentar através da produção científica

Identifica e analisa criticamente a produção científica brasileira, no campo da saúde pública, sobre os organismos geneticamente modificados, no que concerne à (in)segurança alimentar. Para tanto, realizou-se uma revisão bibliográfica nos portais do Scientific Eletronic Library Online (SciELO) e da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes). Dos 716 trabalhos encontrados, apenas oito abordam a segurança alimentar dos transgênicos, através, principalmente, da exposição aos riscos e das incertezas desses produtos para a saúde e o meio ambiente. A principal conclusão do estudo refere-se ao fato de que os oito trabalhos analisados discursam, não sobre a segurança, mas sobre a insegurança dos alimentos geneticamente modificados.

Roundup causes non-alcoholic fatty liver disease at very low doses

Cutting-edge molecular profiling analyses reveal that the popular weedkiller Roundup causes liver damage at doses permitted by regulators. Report: Claire Robinson

The weedkiller Roundup causes non-alcoholic fatty liver disease at very low doses permitted by regulators worldwide, a new peer-reviewed study shows. The study is the first ever to show a causative link between consumption of Roundup at a real-world environmentally relevant dose and a serious disease.

Conflicts of Interest in GM Bt Crop Efficacy and Durability Studies

Public confidence in genetically modified (GM) crop studies is tenuous at best in many countries, including those of the European Union in particular. A lack of information about the effects of ties between academic research and industry might stretch this confidence to the breaking point. We therefore performed an analysis on a large set of research articles (n = 672) focusing on the efficacy or durability of GM Bt crops and ties between the researchers carrying out these studies and the GM crop industry. We found that ties between researchers and the GM crop industry were common, with 40% of the articles considered displaying conflicts of interest (COI). In particular, we found that, compared to the absence of COI, the presence of a COI was associated with a 50% higher frequency of outcomes favorable to the interests of the GM crop company.
