A recent study published in the Journal of Exposure Science and Environmental Epidemiology has revealed widespread human exposure to food contact chemicals (FCCs), highlighting significant gaps in biomonitoring and toxicity data. Led by researchers from the Food Packaging Forum and four academic institutions, the study identified 3,601 FCCs in human samples such as urine, blood, and breast milk—25% of the 14,000 known FCCs used in food packaging and contact materials.

Dr. Birgit Geueke, the study’s lead author, emphasized the link between these chemicals and human health, pointing out that many have been overlooked in prior research. The study also found that groups like bisphenols, PFAS, phthalates, and metals, widely detected in human samples, pose hazard risks and are associated with health concerns. Dr. Jane Muncke, senior author, expressed alarm over the fact that while food contact materials (FCMs) may comply with regulations, they can still transfer harmful chemicals to humans.

Additionally, the study noted that synthetic antioxidants and oligomers, which transfer from packaging to food, are largely absent from current monitoring programs, with limited understanding of their effects on humans. Co-author Dr. Ksenia Groh emphasized the need for more research on these substances, which are widely used but under-studied.

The researchers hope this work will inform better regulation and the development of safer alternatives to current FCMs. The data are available in the new FCChumon database, which aims to support future research on the health impacts of FCCs and improve understanding of human exposure to these chemicals.
