Tea Bags Can Leach BPA, Thousands of Microplastics per Cup
A new study reveals that popular plastic mesh tea bags shed measurable amounts of bisphenol A and up to nearly 2,500 microplastic particles into a single cup of hot water. University researchers in Türkiye tested 28 tea brands during simulated brews, discovering that infusions contained averages ranging from 555 to 2,498 particles per cup. The findings highlight a hidden source of daily chemical and plastic exposure for consumers who use pyramid-shaped and silky commercial tea bags.

Plastic Tea Bags Release Microplastics and BPA Into Brews
A new study reveals that popular plastic mesh tea bags shed measurable amounts of bisphenol A and up to nearly 2,500 microplastic particles into a single cup of hot water. University researchers in Türkiye tested 28 tea brands during simulated brews, discovering that infusions contained averages ranging from 555 to 2,498 particles per cup. The findings highlight a hidden source of daily chemical and plastic exposure for consumers who use pyramid-shaped and silky commercial tea bags.
Why it matters
Microplastics and endocrine-disrupting chemicals like BPA have raised health concerns due to their links with cellular damage, cardiovascular issues, and certain cancers. The latest study adds to growing scientific scrutiny regarding how consumer goods leach synthetic materials into food and beverages. Experts suggest shifting toward alternative brewing methods, such as loose-leaf tea with traditional infusers, to reduce personal exposure.
What is confirmed
- Some plastic tea bags steep between 555 and 2,498 microplastic particles into every cup.
- Researchers tested 28 tea brands to evaluate microplastic and chemical release in hot water.
- Plastic mesh tea bags release measurable bisphenol A and plasticizers during a simulated brew.
Still unconfirmed
- Specific brand names affected by the high levels of microplastic and BPA leaching have not been fully detailed in public summaries.
What to watch next
- Further peer-reviewed studies identifying specific commercial tea brands with the highest and lowest leach rates
- Official health agency guidance regarding acceptable daily intake limits for microplastics ingested via beverages
