The German Federal Institute for Risk Assessment (BfR) is a scientific institution within the portfolio of the Federal Ministry of Food and Agriculture (BMEL) in Germany. It advises the Federal Government on questions of food, chemical and product safety. The BfR conducts its own research on topics that are closely linked to its assessment tasks. The Food Safety Department assesses the substance risks from food. The substances for assessment may be contained naturally as ingredients in food or may be admixed to food as additives or flavourings. Undesirable substances, which reach food during manufacturing, storage or treatment processes, are also evaluated. This includes also micro- and nanoplastics. The topic of micro- and nanoplastics gained much public attention, since it has been discovered recently that microplastic particles reach the human gastrointestinal tract via food products. Microplastics is defined as polymer particles of different materials in a size range between 1 μm (0.001 mm) and 5 mm. Although, methodological challenges still exist for these particles, there have been scientific investigations, to get a clearer view on its intestinal toxicity. Particles bigger than 1.5 μm are unlikely to be bioavailable and effects are only detected in overload situations, decades above realistic exposure scenarios. The situation for particles smaller than 1 μm, however, is much more challenging.
