Introduction to EU Dietary Risk Assessment and the Evaluation of Metabolites

Hannah Bayley holds a BMedSci Medical science honours degree from Oxford Brookes University. Following her studies, she acquired experience in drug metabolism and pharmacokinetic study coordination for a leading CRO where her role included the planning and reporting of multidisciplinary projects including in-vivo metabolism, pharmacokinetic, absorption, distribution, metabolism, and excretion (ADME) and quantitative whole-body autoradiography (QWBA) studies. Her experience also encompasses quantitative data analysis and interpretation. During her time at Exponent she has developed within the chemical regulation and dietary exposure team, were she continues to manage and contribute to a multitude of regulatory submissions including active substance approvals, product authorisations, MRL applications and import tolerance applications for crop protection chemicals. Additionally, she regularly prepares and coordinates the submission of residues and toxicology dossiers for evaluation by the Joint Meeting on Pesticide Residues (JMPR) to influence Codex MRLs.

Maria L. Pellizzaro is Managing Scientist at Exponent and has extensive knowledge of many in silico methods (QSAR). She also has experience in a wide range of human health exposure models for pesticides, biocides and industrial and consumer chemicals, for use both at European Union and individual Member State Level. She has developed strategies to address specific regulatory toxicology and exposure concerns, which have included the use of higher tier exposure assessment approaches.

Nell Townsend is a pesticide residues and dietary exposure specialist with broad experience evaluating studies and conducting consumer risk assessments for registration of crop protection chemicals. Her expertise includes evaluating residue and metabolism data packages, conducting data gap analyses and preparing EU regulatory dossiers. Her experience also includes the assessment of physical, chemical and technical properties of pesticides and biocides (including product families) and the evaluation of methods of analysis. She provides expert scientific support to clients on the practical, technical, and regulatory aspects of pesticide and biocide dossiers to support active substance approvals or product authorisations.
