The European Food Safety Authority (EFSA) has developed a suite of open access tools to estimate dietary exposure to food-borne chemical hazards. The tools are tailored to several regulatory domains within EFSA’s remit (e.g. food and feed additives, pesticide residues, contaminants and food enzymes) and are intended for use by EFSA experts, industry applicants of regulatory product dossiers, researchers or any stakeholder with an interest in estimating dietary exposure using European food consumption data. The majority of the tools are based on FoodEx2, EFSA’s food classification and description system as well as the EFSA Comprehensive European food consumption database. This paper provides an overview of these open access tools, the regulatory framework in which they were developed as well as data sources used.

欧洲食品安全局（EFSA）开发了一套开放获取工具，用于估计饮食中食源性化学危害的暴露程度。这些工具是针对EFSA职权范围内的多个监管领域（例如食品和饲料添加剂，农药残留，污染物和食品酶）量身定制的，旨在供EFSA专家，监管产品档案的行业申请人，研究人员或与之相关的任何利益相关者使用使用欧洲食品消费数据估算饮食摄入量。大多数工具都基于FoodEx2，EFSA的食品分类和描述系统以及EFSA欧洲食品消费综合数据库。本文概述了这些开放访问工具，开发它们的监管框架以及所使用的数据源。
