A conference about the conflict between public policy and independent science, in honour of Dr. Árpád Pusztai (1930 – 2021)

Edinburgh (UK), 26 – 27 May 2023 | open to both on site and online participation

The conference will be in two parts:

  • Day one (26 May 2023) will honour Dr Árpád Pusztai (who passed away in 2021) and will recall his work and discuss the controversies of his later findings.
  • Day two (27 May 2023) will probe the continuing conflicts between public policy and critical science, with the purpose of improving public understanding and use of science.

Organised by European Network of Scientists for Social and Environmental Responsibility, Critical Scientists Switzerland, Mariolopoulos-Kanaginis Foundation for the Environmental Sciences & Association des amis de la génération Thunberg

Day 1: A memorial to Dr. Árpád Pusztai

Friday, 26 May 2023, 15:00 – 22:00 GMT

In 1998, Dr. Árpád Pusztai, a world expert on plant lectins, sparked a public debate on the safety of genetically modified (GM) food by speaking on the British TV programme World in Action about the health damage he found in rats fed GM potatoes containing lectins in preliminary tests. As a result of this brief TV interview, he was suspended from his job at the Rowett Research Institute in Aberdeen, Scotland.

His research had been commissioned by the Agriculture, Environment and Fisheries Department of the Scottish Office (the precursor of the present Scottish government). The sharp and prolonged criticism from scientific circles which followed the events, has never been substantiated by tenable scientific arguments. Indeed, his findings have been supported by other independent research that also casts doubt on the safety of some GM food.

Pusztai’s standing as a biochemist and specialist on animal feed was recognised and beyond doubt before these events.

This memorial will describe this episode. We hope we can lay the controversies to rest.

Day 2: Conference “The Integrity of Science”

Saturday, 27 May 2023, 10:00 – 17:00 GMT

Pusztai’s story is not unique. Fundamental scientific research is often suppressed in areas where human or environmental health or biodiversity are shown or suspected to be at risk, and even when a new finding is merely unconventional.

In day two, the corruptive influence of entrenched or commercial interests on science in the last decades will be described and analysed, with references to many similar cases (tobacco, asbestos, pesticides, electromagnetic radiation, PFAS, climate change, COVID19, etc.). The list of lessons not learned from early scientific warnings[1] still grows. The grave consequences of this corruption of science for the future of humanity and our planet will be the focus of the conference.

We hope that this conference will inspire fuller appreciation of the values of science, beyond the community of scientists, especially including young scientists.
