Chlorpyrifos is toxic and persistent, including causing brain damage in children. After being banned in the EU and the US, sales and use ended within months. Health Canada is allowing three more years of use in Canada.
Courts in Canada and the US have ruled in favour of groups challenging glyphosate risk assessments. Concerns over possible industry influence are heightened with falsification re. nHL in final US ATSDR report on glyphosate.
A regulatory conclusion that an environmental exposure poses an “acceptable risk” is initially based on little data. Ethically, regulators should follow up to detect harms at the earliest possible opportunity. Relying on epidemiology can result in harms to generations.
A Parliamentary Petition to ban glyphosate and to reduce pesticide use in Canada is worthy of support. Substantial pesticides reduction and alternative strategies are essential to avoid regrettable substitutes, and importantly to support biodiversity, healthy environments, food and people. Indeed, a stated goal of the upcoming UN Biodiversity Conference (COP-15) is to reduce pesticides by two thirds. Organic, regenerative agriculture needs more support.
