Modelling Migration from Plastics into Foodstuffs as a Novel and Cost [or: Efficient Tool for Estimation of Consumer Exposure from Food Contact Materials Why was the project unavoidable?] e Intention & structure of the project Starting date: 01/03/2003 European Commission

4 Why the project? Modelling Migration from Plastics into Foodstuffs as a Novel and Cost simple Efficient and Tool for Estimation of Consumer Exposure from Food Contact Materials e CT Migration tests should be simple and reproducible and have therefore been carried out so far using in the first place Starting date: 01/03/2003 food simulants and not foodstuffs.

9 Why the project? CT Modelling Migration from Plastics into Foodstuffs More as a Novel and Cost recent Efficient Tool for examples Estimation of Consumer Exposure from Food Contact Materials e examples from the ITX crisis [photo initiator in printing inks transferred to food via set-off] revealed again weaknesses of the Starting date: 01/03/ /572/EC system European Commission

16 The basic equation to calculate FCM related exposure: Exposure = C i P i C M n i via migration modelling where: C i = consumption rate of a particular food i P i = relative packaging usage of a given FCM for a particular food i M i = migration rate from a given FCM into a particular food i n = number of foodstuffs considered for the exposure estimation

17 ... was to develop an into-food migration model as a novel and economic tool that may be applicable in two different ways: (1) As a stand alone tool to estimate exposure related migration within the conventional frame conditions of the EU food regulatory evaluation system thus applying a worst case exposure scenario, i.e.: Exposure = M i (2) In conjunction with statistical data obtained from food consumption and plastics packaging surveys to estimate realistic or worse-case exposure for any situation of interest, i.e.: Exposure = C i Pi C M n i

19 ... for EU Commission and EFSA In general: Supporting present and future EU legislation for FCM In particular: - Scientific/technical technical basis for actualisation of Directive 85/572/EEC issues - Bringing more light into the dark related to meet specific restrictions (SMLs)) on the level of foodstuffs - Supporting and plausibilisation of exposure estimations in context with petitions and setting specific restrictions

20 ... for Industry Packaging industry: - Early (in the packaging development process) ) and food type specific compliance evaluation - Cost efficient compliance ensurance Food industry: - Improving or even establishing independent house- internal quality assurance tools and this in a better product specific way - More knowledge about diffusion and partitioning processes or organic compounds in foods

21 ... for the Consumer including consumer protectors - Better and more effective surveillance of FCM - (Further) familiarisation with the idea of Migration Modelling and increasing acceptance of calculated migration values - (Somewhat) cheaper packed foodstuffs? And with the possible effect of... decreasing the FCM related conflict potential and generating more confidence in FCM safety?
