Advances in the risk management of unintended presence of allergenic foods in manufactured food products--an overview.

Food allergy is a relatively recent newcomer to the ranks of food safety issues, only being effectively recognised as such in the last 25-30 years. This recognition, allied with the near impossibility of avoiding the unintended presence of small, yet potentially dangerous residues of allergenic constituents, brought with it the need to assess and manage the resulting risk. This paper provides an overview of the development and current knowledge and thinking on risk assessment and its application to risk management of food allergens. It also discusses the associated challenges, in particular those around communicating meaningfully that risk to allergic consumers, including the use of precautionary labelling. The paper also provides an introductory context to the more detailed analyses of these issues in the following papers, based on the deliberations of a recent stakeholder workshop. The paper concludes that consistent risk management approaches using agreed quantitative action levels based on scientifically robust principles will provide optimal protection to allergic consumers. Growing amounts of data from oral food challenges along with the parallel development of risk assessment methodologies, such as probabilistic modelling, offer a realistic possibility of agreement among stakeholders on such levels in the near future.
