Risk, Uncertainty and Precaution in Science: The Threshold of the Toxicological Concern Approach in Food Toxicology
1Department of Humanities, Social and Political Sciences, Swiss Federal Institute of Technology, Clausiusstrasse 49, 8092, Zurich, Switzerland. bschir@phil.gess.ethz.ch.
The precautionary principle should guide the development and use of risk assessment tools due to scientific uncertainty. Current methods, like the threshold of toxicological concern in food toxicology, do not fully meet this epistemic standard.
Area of Science:
- Environmental science
- Philosophy of science
- Food toxicology
Background:
- Environmental risk assessment frequently encounters significant scientific uncertainty.
- The precautionary principle is commonly used to guide decision-making amid uncertainty.
- Uncertainty influences both the application and development of scientific models.
Purpose of the Study:
- To argue for exercising precaution during the development of risk assessment tools, not just their application.
- To examine the implications of this broader precautionary approach.
- To evaluate the threshold of toxicological concern (TTC) approach in food toxicology against an epistemic precautionary principle.
Main Methods:
- Philosophical analysis of scientific uncertainty and precaution.
- Literature review in the philosophy of science.
- Case study analysis of the threshold of toxicological concern (TTC) approach.
Main Results:
- Precaution should be applied during the development phase of risk assessment tools.
- The threshold of toxicological concern (TTC) approach in food toxicology was analyzed.
- The TTC approach was found to be insufficient according to epistemic precautionary standards.
Conclusions:
- The precautionary principle should encompass the development of scientific tools for risk assessment.
- The threshold of toxicological concern (TTC) approach in food toxicology requires re-evaluation.
- A more robust application of the precautionary principle is needed in scientific tool development and risk assessment.
