Earlier this year EFSA undertook a thorough revision of its 2011 guidance on the risk assessment of nanomaterials (NMs) used in food and feed production. Final guidance on Part 1 has now been issued and provides an overview of the information requirements and steps needed to perform health risk assessments for humans and other animals. Key topics include the following:

  • unambiguous identification and detailed characterisation of NMs (their components, including surface constituents, as well as any impurities)
  • hazard identification/characterisation, including the suitability (or not) of existing in vitro and in vivo assays
  • potential changes in properties and biokinetics of NMs compared with corresponding non-NMs, leading to altered toxicological effects
  • exposure assessment
  • risk characterisation, including where the use of NM-specific uncertainty factors may be appropriate
  • circumstances under which requirements for NM-specific data could be waived or grouping/read-across could be applied
  • ongoing developments in alternative testing approaches, mode of action and adverse outcome pathways
