Microplastics aren’t just floating in the ocean or hiding in synthetic clothes — they’re also sneaking into your dinner.
A new study published in npj Science of Food shows that everyday use of plastic packaging and kitchen items like bottles, bags and cutting boards can release tiny plastic particles directly into our food. Researchers from the Food Packaging Forum analyzed 103 scientific studies and found that these plastic food contact articles (or FCAs) are an overlooked source of contamination.
“This is the first systematic evidence map to investigate the role of the normal and intended use of food contact articles in the contamination of foodstuffs with MNPs,” said Dr. Lisa Zimmermann, lead author of the new study and Scientific Communication Officer at the Food Packaging Forum. “Food contact articles are a relevant source of MNPs in foodstuffs; however, their contribution to human MNP exposure is underappreciated.”
The team compiled their findings into a new interactive database called FCMiNo. The dashboard lets users explore where and how micro- and nanoplastics show up depending on the type of food contact material, how the study was run and what kind of plastic particles were found.
“This systematic evidence map helps fill gaps in knowledge on the source of MNPs in foodstuffs,” says Dr. Jane Muncke, co-author of the study and Managing Director and Chief Scientific Officer at the Food Packaging Forum. “However, it also shows that additional research is needed to better characterize MNP migration related to FCA materials and uses. Importantly, implementing a harmonized testing and reporting framework is key to ensuring reliable and comparable data, which can inform future policy decisions.”
The researchers also emphasized that regulations requiring microplastic migration testing in food packaging could better protect consumers. In the meantime, opting for plastic-free packaging or kitchen tools is one way individuals can reduce personal exposure.
This study was funded by project-related grants from the Spronck Foundation and by the Food Packaging Forum’s unrestricted donations. Full funding sources are listed at foodpackagingforum.org/about-us/funding.
