Dr. Marion Nestle, longtime NYU professor of nutrition, food studies, and public health, with additional faculty roles at UC San Francisco and Cornell, is best known for analyzing the intersections of food, politics, and health, often exposing how government policy, corporate lobbying, and food industry marketing shape what we eat.
Microplastics: research and commentary
I’ve been collecting items on microplastics, for which research is finding increasing evidence for harm to human and environmental health. Here are some relatively recent examples of what’s out there on this topic.

- BBC News: Study Identifies Microplastics in Majority of Commercial Pet Foods: Researchers at the universities of Sussex and Exeter found microplastics in 16 of 19 pet food brands, with higher exposure linked to feeding patterns. The findings highlight potential food system contamination and prompt calls for regulatory testing. Read More
What’s needed?
- Food and Water Watch: 250+ Health Professionals Call on EPA to Monitor Microplastics in Drinking Water: Over two hundred and fifty doctors, nurses and other health care and public health professionals and organizations sent a letter to the Environmental Protection Agency (EPA) urging the agency to add microplastics to the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) and monitor for these contaminants in our drinking water.

And what is the EPA doing about this? Nothing, alas.

EPA Fails to Take Meaningful Action on Microplastics: Food & Water Watch condemns EPA for failing to include microplastics in proposed drinking water monitoring program. The Environmental Protection Agency (EPA) has released a draft of the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6), which sets forth which contaminants the agency will require monitoring for in drinking water. The draft rule shows that EPA does not plan to require monitoring for microplastics over the next five years.
