Hidden Pollutants in Food: Evidence of Small Microplastic Particles (100–5 µm) in Refined Sugar from the Italian Market

Summary

Researchers analyzed samples of refined sugar from the Italian market and detected small microplastic particles ranging from 5 to 100 micrometers in size, confirming that microplastics are present in a widely consumed everyday food product. The findings add to growing evidence that humans are routinely ingesting microplastics through common foods, even highly processed ones like refined sugar where contamination pathways are not immediately obvious. This raises questions about cumulative dietary exposure and the need for food safety standards around microplastic contamination.
