Exposure of U.S. adults to microplastics from commonly-consumed proteins

…

Highlights

• We observed microplastic contamination ?45 ?m in 16 U.S. protein products.
• Highly-processed products contained the most microplastics per gram.
• Microplastic contamination did not differ between brands or store types.
• Mean U.S. adult exposure from consuming these proteins is >11,000 microplastics/year.
• Maximum U.S. adult exposure from these proteins is ?3.8 million microplastics/year.
