Microplastic Exposure: Seafood Not the Main Culprit
Research led by Ted Henry, professor at Heriot-Watt University, suggests that people are more likely to ingest microplastics from bottled water and indoor air than from eating seafood.
A study published in Environmental Science & Technology Letters found that eating seafood contributes just 1–10 microplastic particles per day, comparable to other foods like chicken.
- Bottled water may contain 10–100 microplastic particles daily
- Indoor air exposure can reach 100–1,000 microplastic particles a day
More than 70% of scientific and media reports on microplastics in food have focused on seafood
Author's summary: Seafood is not a major source of microplastic exposure.
