A Forced Evolution?

This research paper examines the challenges facing the Codex Alimentarius Commission due to increasing scientific uncertainty and the resulting political tensions in international food standard-setting. The author argues that the Commission must evolve by incorporating elements of the precautionary principle to maintain its legitimacy and functionality in a globalized trade environment.

• The Codex Alimentarius Commission, established in 1962 by the FAO and WHO, has transitioned from an obscure scientific body into a highly political forum. While its standards are technically voluntary, the WTO's Agreement on Sanitary and Phytosanitary Measures (SPS) has effectively turned them into a 'ceiling' or 'voluntarism under duress,' as countries following Codex standards are presumed to be consistent with WTO rules.
• Four primary trends are increasing the problem of scientific uncertainty for Codex: the rapid growth of biotechnology and chemicals (where many substances remain untested for human health effects), increasing environmental degradation and public concern, the explosive growth of world trade, and the institutional changes imposed by the WTO's SPS Agreement.
• The author identifies the precautionary principle as the appropriate response to scientific uncertainty, highlighting seven common themes: preventative anticipation, room for error, proportionality of response, reversal of the onus of proof, a continuous search for greater certainty, openness of process, and an emphasis on finding alternatives.
• The inability of Codex to reach consensus on high-stakes issues, such as the use of beef hormones and the labelling of genetically modified organisms (GMOs), demonstrates the failure of traditional standard-setting when faced with uncertain science and conflicting national interests.
• To adapt, the author proposes that Codex shift its focus from risk management (setting final standards) toward supporting national-level risk management through risk assessment and guidelines. This would allow countries to exercise precaution without being forced by WTO rules to justify exceeding a non-existent international standard.
• The paper suggests three additional evolutionary steps for Codex: maintaining an ongoing search for scientific certainty through its expert committees, reversing the onus of proof (requiring proponents of new technologies to prove safety), and increasing openness to improve decision quality and public legitimacy.
