Árpád János Pusztai (8 September 1930 – 17 December 2021) was a Hungarian-born British biochemist and nutritionist who spent 36 years at the Rowett Research Institute in Aberdeen, Scotland. He was a world expert on plant lectins, authoring 270 papers and three books on the subject. In 1998, Árpád Pusztai publicly announced that the results of his research showed feeding genetically modified potatoes to rats had negative effects on their stomach lining and immune system. This led to scientific criticism. Pusztai was suspended and his annual contract was not renewed. The resulting controversy became known as the Pusztai affair. উৎস: Wikipedia (en)
