Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize
This research article suggested that long-term exposure to GMOs and/or Roundup can increase chances of cancer and kidney and liver problems, even when within legal limits of contamination. It received great attention in popular media, and was discredited by other scientists working in the discipline, and ultimately retracted by the journal that published it. Several of the letters to the editor are included as links to give a larger context to the reader around the study, its authors, and the many criticisms that led to its retraction. Although the work is discredited, it makes an excellent case study for those teaching scientific ethics, statistics, and genetic modification.
