More and more studies have detected microplastics in various human tissues and body fluids. Recent research findings by a team led by Professor Matthew Campen (see programme) from the University of New Mexico show that the concentration of microplastics in liver and brain samples from 2024 was significantly higher than in comparative samples from 2016. Particularly striking was the concentration measured in the brain, which in some cases was up to 30 times higher than in the liver or kidneys. The results of this study are currently the subject of controversial debate in the scientific community. Other studies have found microplastics in human blood, lungs and reproductive organs, among other places.
However, these findings do not yet provide evidence of health effects, as the studies are often based on small samples and/or there are methodological uncertainties in the identification and quantification of microplastics. In addition, previous findings only show correlations, not causal relationships. According to the current state of scientific knowledge, microplastics pose a relatively low health risk to humans. This is because most particles are not bioavailable, and the amount ingested is probably too small to cause any health effects. Nevertheless, further research is needed – in particular to better understand exactly how microplastics and even smaller nanoplastics work in the body. Validated measurement methods for the reliable determination of microplastics and nanoplastics in biological material are also needed.
While the scientific assessment is currently rather reassuring, there are increasing indications of a different perception among the general public: the topic is met with great interest, but in many cases there is little knowledge – rather, concern about health effects is widespread. In addition to aspects of toxicology, entry routes, exposure, and methodology, this discrepancy between scientific knowledge and public perception will also be a topic of discussion at the Consumer Protection Forum. Against this backdrop, experts from various disciplines will provide insights into the current state of science and highlight areas where further research is needed. In the afternoon, representatives from politics, business and society will share their perspectives and discuss them with participants.

BfR press conference on 2 December 2025
Before the forum begins, we invite media representatives to a hybrid introductory press conference, which will take place at 9 a.m. in the Press and Visitor Centre of the Federal Press Office (Reichstagufer 14, 10117 Berlin). Here you will have the opportunity to talk to BfR scientists about microplastics and the BfR's work on the topic and to obtain further information. Please register by emailing pressestelle@bfr.bund.de.
Further information on microplastics is available on the BfR website

About the BfR
The German Federal Institute for Risk Assessment (BfR) is a scientifically independent institution within the portfolio of the German Federal Ministry of Agriculture, Food and Regional Identity (BMLEH). It protects people's health preventively in the fields of public health and veterinary public health. The BfR provides advice to the Federal Government as well as the Federal States (‘Laender’) on questions related to food, feed, chemical and product safety. The BfR conducts its own research on topics closely related to its assessment tasks.
