Berlin. There are many toxic substances in packaging that are transferred to food. The health consequences are often unclear.
More than 3,600 chemicals approved for use in packaging, kitchenware or food processing equipment have been found in humans. This is the result of one Study Swiss, American and Czech researchers under the leadership of the foundation Food Packaging Forum. The chemicals were found in blood, hair or breast milk.
Among the substances found are highly toxic Compounds such as PFAS, bisphenol, metals, phthalates and volatile organic compounds. These substances can be responsible for cancer, hormone imbalances and other health problems. For many, the possible health consequences are still largely unexplored – for example synthetic antioxidants that are used as preservatives or oligomers that stabilize the ink on packaging.
“What is certainly worrying is that we have a strong connection that shows that some dangerous Chemicals from packaging into food, so packaging contributes to pollution,” says Birgit Geueke, co-author of the study at the Food Packaging Forum, a Zurich-based nonprofit organization that advocates for stricter regulations.
The study examined approximately 14,000 chemicals approved for food contact. To do this, databases were checked and scientific literature examined for evidence of whether the chemicals had been found in humans. However, the researchers limit the fact that people can also use the chemicals examined in others connections may be exposed and food packaging is not solely responsible for this.

According to the study, this is particularly treacherous Plastic – a material that can contain thousands of chemicals. Silicone and coatings on metal cans also contain many substances that have hardly been researched, said co-author Geueke. There is also a layer of plastic on many paper and cardboard packaging. Factors such as storage temperature and the fat and acid content of food can also determine the extent to which it is contaminated with chemicals from packaging. Food in small packaging can also be more contaminated.
The study authors suggest more research into the potential health risks of chemicals in food packaging. In addition, their use would have to be stricter regulated become. And they have a practical everyday tip: pour food into glass containers as quickly as possible after buying it – these are the least contaminated.
