Risk Assessment in the 21st Century (RISK21) Committee

Mission Statement

The committee’s mission is to promote a transparent, purpose-driven, structured approach to risk assessment based on key principles, including problem formulation, tiered integration of both hazard and exposure at each step, and fit for purpose.

Version 2.0 of the RISK21 webtool is now available. To access the RISK21 webtool, please visit risk21.org.

 

Working Groups

  • Brazil Pesticide Use Information Tool

    The Committee contracted out the development of a database of information necessary to estimate pesticide exposure (and obtain parameters for exposure models) in Brazil. Pesticide use and application information are being extracted from the Brazilian Health Regulatory Agency (ANVISA) monographs and from Agrofit, Brazil’s pesticide registration tool, and pulled into an easily searchable, publicly accessible database.

    A project advisory team is monitoring and supporting the project, which is expected to be completed in the first quarter of 2023.

  • Argentina Pesticide Residue Information Tool

    A tool developed to inform pesticide residues in food in Argentina was funded and developed for SENASA. It resulted from a partnership between HESI, Buenos Aires and Austral Universities, and SENASA. A manuscript co-authored by all partners and featuring this effort will be developed in the coming year.

  • Pesticide Labeling Harmonization

    Initiated discussion to explore how to better harmonize pesticide labels by:

    • Identifying the needs across various countries/regions
    • Communicating ongoing work in this space (e.g., smart labels, e-labels, etc.) within and outside of OECD (webinar will be scheduled in Q4 2022 to share updates)
    • Working to identify potential partnerships
  • RISK21 Toolkit Update

    Discussions have been initiated to improve both the RAFT tool and RISK21 matrix and make them more user-friendly.
