Microplastics Found in Food: Packaging a Key Source of Contamination
updated June 25, 2025
Microplastics are increasingly recognized as a pervasive environmental contaminant, and new research highlights their presence in our food supply.A recent study indicates that food packaging, even through normal use, contributes significantly to microplastics contamination. This adds to existing concerns about the potential health risks associated with ingesting these particles.
Researchers at the Food Packaging Forum, Swiss Federal Institute of Aquatic science and technology (Eawag), and the norwegian University of Science and Technology reviewed 103 studies and found that opening plastic bottles, steeping tea bags, and chopping on plastic cutting boards can all release micro- and nanoplastics (MNPs) into food. The study,published in npj Science of Food,emphasizes that food contact articles (FCAs) are a relevant,yet underappreciated,source of MNPs.
Dr. Lisa Zimmermann, lead author and Scientific Interaction Officer at the Food Packaging forum, stated, “Food contact articles are a relevant source of mnps in foodstuffs; however, their contribution to human MNP exposure is underappreciated.” The data collected is accessible through the FCMiNo dashboard, allowing users to explore data by FCA type, food contact material, and MNP characteristics.
Removing plastic from groceries or steeping a tea bag can introduce microplastics. Dr.Zimmerman noted that repeated opening and closing of bottles, whether glass or plastic, sheds micro- and nanoplastics into the beverage. “The research shows the number of microplastics increases with each bottle opening, so thus we can say it’s the usage of the food contact article which leads to micro- and nanoplastic release,” she told CNN.
Dr. Zimmerman told The Washington Post, “Plastic is present everywhere. We need to know what we can do.” She suggests avoiding storing food in plastic and heating plastic containers,while acknowledging that the factors leading to micro- and nanoplastic release are not fully understood.
Dr. Jane Muncke, Managing Director and Chief Scientific Officer at the Food Packaging Forum, warns that ultraprocessed foods pose a higher risk of contamination due to increased contact time with plastic food processing equipment.
David andrews,acting chief science officer at the Environmental Working Group,told CNN, “This new study highlights food packaging and processing equipment as possibly significant sources of microplastic contamination in the food we eat, and ultimately in our bodies. This study should raise alarm bells.”
surprisingly, another study revealed that drinks sold in glass bottles can have more microplastics than those in plastic bottles. Researchers from France’s state food agency ANSES found that glass bottles of cola, lemonade, iced tea, and beer had at least five times the amount of particles than plastic bottles or cans.
PhD student Iseline Chaib, who conducted the research, explained that the paint on the outside of the caps sealing the glass bottles is the source of the contamination. The team suggested manufacturers use a cleaning method of blowing air in the caps, and rising with water and alcohol, which could reduce contamination by 60 percent. Consumers were also advised to rinse caps before putting them back on.
Furthermore, a paper by West Virginia University biology undergraduate student Isabella Tuzzio found microplastics in every fish sampled from central appalachian streams, averaging 40 pieces per fish. The study points to agricultural activity, wastewater treatment, and atmospheric deposition as potential sources of microplastic pollution.
Ms. Tuzzio said, “Microplastics are coming from everyday sources like synthetic fibers from laundry and plastic beads in exfoliating face washes. They’re now everywhere, from our streams to remote deserts and even the human body.”
She added, “These plastics are small, but their impact is massive. They carry pollutants, heavy metals and antibiotics…As you work your way up the food chain, there are heavily concentrated levels of these plastics. It’s a problem for them and for us, too.”
The widespread presence of microplastics in our food system and bodies raises significant concerns about potential health risks. While more data is needed to fully understand the long-term effects, the evidence suggests that exposure to microplastics is not beneficial.
“this systematic evidence map helps fill gaps in knowledge on the source of MNPs in foodstuffs.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,” Dr. Muncke believes.
What’s next
Further research is crucial to fully understand the sources, pathways, and health impacts of microplastics. Efforts to reduce plastic consumption, improve waste management, and develop safer alternatives are essential to mitigate the risks associated with microplastic contamination.
