Do microplastics in food also carry antibiotic residues?

What's actually in it

Microplastics in soil don't just sit there. They're chemically active. Their large surface area relative to their volume makes them efficient absorbers of other contaminants. Antibiotic residues from livestock manure used as fertilizer, heavy metals from pollution, and PFAS from agricultural chemicals all get absorbed onto plastic particles in soil.

Plant roots absorb these plastic particles, and the absorbed contaminants travel into the food. You don't just get the plastic. You get everything the plastic was carrying.

What the research says

A 2026 study in J Hazard Mater tracked microplastics from agricultural soils into food crops. They found that microplastics served as vectors for antibiotics, heavy metals, and PFAS from soil into crops. Crops grown in microplastic-contaminated soil carried not just the plastic particles but the chemical cocktail absorbed onto them.

This is a food chain concern that's hard to control at the consumer level. It reinforces the case for reducing agricultural plastic use and choosing food grown in lower-contamination settings where possible.

For storage and preparation of produce, use glass food storage and bamboo kitchen tools to avoid adding more plastic contact on top of what's already in the food.
