Your Vegetables Are Full of Microplastics

The vegetables in your fridge have microplastics inside them. Not just on them. Inside the plant tissue. They absorbed the plastic from the soil and water while growing.

What the Study Found

A 2026 study in the Journal of Agricultural and Food Chemistry reviewed the evidence on vegetable-borne microplastics. Researchers found that plants take up micro and nanoplastic particles through their root systems. The particles travel through the plant and accumulate in the parts you eat: leaves, stems, and fruits.

The study lays out a research agenda for food-chain risk assessment because right now, nobody knows exactly how much plastic you're eating with every salad. The evidence says it's there. The question is how much it matters.

How Plastic Gets Into Plants

Agricultural soil is contaminated with microplastics from plastic mulch, biosolids (treated sewage used as fertilizer), irrigation water, and atmospheric deposition. Plants absorb water and nutrients from this soil, and the plastic particles come along for the ride.

What You Can Do

Buy organic when possible (organic farms use less plastic mulch). Wash produce thoroughly, though washing won't remove particles that are already inside the plant. Support farmers who avoid plastic mulch and synthetic fertilizers. Grow your own vegetables in clean soil when you can.
