Comment expliquer que le projet de politique alimentaire du Canada ignore le dossier des pesticides alors que la récente politique bioalimentaire du Québec évoque vaguement la question, mais sans engagements significatifs? Pourquoi évacuer ainsi l’analyse des enjeux et des effets sanitaires et environnementaux préoccupants des pesticides et notamment du glyphosate, premier pesticide au monde, en croissance exponentielle, qui, déclaré cancérogène probable par le Centre international de recherche sur le cancer (CIRC) de l’Organisation mondiale de la santé (OMS) (IARC, 2015), constitue au Canada 56 pour cent des pesticides agricoles et 44 pour cent de ceux du Québec (Santé Canada, 2017a; MDDELCC, 2017)? Presqu’omniprésent dans les champs, les cours d’eau agricoles et dans 30 pour cent des aliments au Canada, le glyphosate est l’objet de vives controverses scientifiques et citoyennes dans le monde entier (Robin, 2008, 2018). En Europe, sa ré-autorisation, suite à deux ans de vives controverses a été limitée à 5 ans. Aux États-Unis, 3,500 victimes d’un lymphome non-hodgkinien attribué au Roundup, premier herbicide à base de glyphosate (HBG) en importance au monde, poursuivent en justice son principal fabricant Monsanto (Gonzague & Michel, 2017) alors qu’en France et en Argentine, des poursuites pour malformations congénitales s’amorcent également contre Monsanto (Foucart, 2018). Cet article examine, dans une approche interdisciplinaire et intersectorielle, les facteurs de la montée en puissance des HBG, leurs principaux effets sur l’environnement et la santé, et les lacunes d’évaluation et d’encadrement des pesticides, contribuant à leur diffusion massive et à leurs effets. Il met aussi en évidence que les projets et politiques alimentaires canadiennes et québécoises, centrés sur le développement de modèles agro-industriels intensifs et technicisés d’exportation soumis à une conception de croissance économique, sont peu compatibles avec les exigences de protection de la biodiversité, de la santé et de la sécurité alimentaire. Or, dans un contexte de globalisation des marchés et d’accords de libre-échange avec l’Europe, plus soucieuse du Principe de Précaution et de droits des consommateurs, la négligence de ces enjeux écologiques et sanitaires risque d’en constituer le talon d’Achille.
In 2015, France recognized hematological malignancies, including non-Hodgkin's lymphoma (NHL), as an occupational disease resulting from pesticide exposure. The IARC of the WHO then declared glyphosate and glyphosate-based herbicides to be genotoxic and probably carcinogenic. In the United States, 125,000 American victims of NHL attributed to Bayer-Monsanto's Roundup have filed lawsuits against the company, while 2.5 million pages of declassified internal documents, the Monsanto Papers, illustrated the incredible manipulations to conceal Roundup’s dangers and to subvert the evaluation and regulatory systems. After three costly convictions, Bayer-Monsanto signed a partial out-of-court settlement of $11 billion and withdrew Roundup from the U.S. domestic market. The structural increase in pesticides, from 2.3 to 4.1 million tons from 1990 to 2018, contributing to the 385 million cases per year of serious and unintentional poisoning, and their threatening impacts on the climate, biodiversity and planetary limits, require going beyond the compensation of certain diseases to highlight the responsibilities of producing firms, regulatory bodies and public authorities : This is the core of this article focused on glyphosate-based herbicides (HBC), the first pesticides in the world, in Canada and Quebec and their links with certain cancers, including non-Hodgkin's lymphoma (NHL).
Despite discourse advocating pesticide reduction, there has been an exponential increase in pesticide use worldwide in the agricultural sector over the last 30 years. Glyphosate-Based Herbicides (GBHs) are the most widely used pesticides on the planet as well as in Canada, where a total of almost 470 million kilograms of declared “active” ingredient glyphosate was sold between 2007 and 2018. GBHs accounted for 58% of pesticides used in the agriculture sector in Canada in 2017. While the independent scientific literature on the harmful health and environmental impacts of pesticides such as GBHs is overwhelming, Canada has only banned 32 “active” pesticide ingredients out of 531 banned in 168 countries, and reapproved GBHs in 2017 until 2032. This article, based on interdisciplinary and intersectoral research, will analyze how as a result of the scientific and regulatory captures of relevant Canadian agencies by the pesticide industry, the Canadian regulation and scientific assessment of pesticides are deficient and lagging behind other countries, using the GBH case as a basis for analysis. It will show how, by embracing industry narratives and biased evidence, by being receptive to industry demands, and by opaque decision making and lack of transparency, Health Canada’s Pest Management Regulatory Agency (PMRA) promotes commercial interests over the imperatives of public health and environmental protection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
