OHEJP-RaDAR-D-JRP3-3.5 Scientific report on a generic comparative exposure assessment model

Description

Introduction

This deliverable focusses on the potential for deriving or creating generic methods for exposure assessments for different production types, different bacteria, different processing etc.. These generic methods may be more crude, but will allow for combining the risks in the different (sub-)categories and may thus help to create a more complete picture of the AMR problems throughout.

In order to study how one could go about developing a generic modelling approach for assessing exposure while taking into account different exposure pathways the following was done. Four in this project independently developed models for three different food chains were compared in a synoptic way identifying conceptual communalities which were then considered central parts of a possible generic exposure modelling approach. The three different food chains were the chicken, pork and seafood chain. Within the seafood chain, there are two models: a comparative exposure assessment model for various types of seafood (fish) and an exposure model focussed on steamed mussels. The models for each food chain have of course their own idiosyncrasies given the different concrete question they try to answer. However, there are still many conceptual communalities, which are useful to highlight in order to identify the generic elements of current state of the art exposure assessment models.

This document goes about its analysis in two steps. In the first step, there is a description of each model for the three food chains. The descriptions are kept at a more general level in order to facilitate the identification of common elements for a generic exposure assessment model approach. Thus, the second step consists in a synoptic analysis of the four models with the focus on the issue of generic modelling framework for exposure assessment might look like.
