A recent study has revealed that microplastics from food packaging are contaminating our food and drinks. The research, published in the journal NPJ Science of Food, highlights that micro- and nanoplastics can be released from plastic wraps, containers, and even glass bottles with plastic-coated metal closures. According to Lisa Zimmermann, the lead author of the study, the number of microplastics increases with each use of the packaging, making food packaging a direct source of contamination.
The study found microplastics in various food and drink products, including beer, canned fish, rice, and mineral water.
Another study by French researchers discovered that glass bottles, especially those with painted metal caps, contained more microplastic particles than plastic bottles or cans. This finding was unexpected, as glass is typically considered an inert material. The research suggests that the polyester paint on the caps may be a source of the particles.
The study also indicated that ultraprocessed foods contain more microplastics than minimally processed foods due to increased contact with plastic processing equipment.
