Plastics Found Inside Vegetable Tissues for the First Time, Raising New Food Safety Concerns

Plastic pollution is not only a problem for oceans and wildlife. It may also be affecting the very food we eat. A new study highlights how nanoplastics can penetrate crops, raising questions about food safety and human health.

Researchers have now shown that some of the smallest plastic particles can move into edible vegetable tissues.

Using radishes as their model, the team demonstrated that nanoplastics can enter roots and travel into the fleshy edible parts.

These plastic particles measure as little as one millionth of a centimeter, making them nearly invisible but not harmless.

This work reveals a potential pathway for humans and animals to consume nanoplastics, beyond seafood and water sources.

The findings also call attention to an emerging food safety concern that could impact agriculture worldwide. If nanoplastics can enter vegetables during growth, then the issue extends far beyond marine ecosystems.
