A recent study has raised serious concerns over scratched non-stick pans. Teflon coated pans can release thousands of microplastic particles in our food. These particles, combined with per- and polyfluoroalkyl substances (PFAS, known as “forever chemicals”), can have harmful health consequences.
What the Study Found
Using molecular imaging and algorithms, the researchers quantified plastic particles shed from scratched cookware during cooking. They found:
- Even one small scratch released at least 9,000 microplastic particles.
- Deep cracks or worn coatings could release up to 2.3 million micro- and nanoplastic particles, which are so small they can penetrate blood cells and even the brain
- This prompted a warning: these “Teflon microplastics” may contaminate food and present serious health threats, from cancer to reproductive issues
The Risk from “Forever Chemicals”
Non-stick surfaces often involve PFAS compounds like PTFE (Teflon), PFOA, and PFOS—chemicals notoriously resistant to degradation and known for persistent presence in human bodies and the environment. PFAS exposures have been linked to liver and kidney disease, high blood pressure, obesity, endocrine disruption, birth defects, and cancer .
Nanoplastics may directly carry PFAS into the body, increasing absorption of these harmful compounds. Over time, the accumulation raises chronic illness risks .
Expert Advice & Alternatives
Health and kitchen experts recommend taking precautions:
- Avoiding scratched or damaged non-stick pans. If the surface shows wear or food starts sticking, it’s time to replace the pan
- Preventing damage. Use wooden or silicone utensils, hand‑wash gently, don’t stack pans without protection, and avoid overheating—empty pans heated above 500 °F can emit toxic fumes and gases
- Switching to safer cookware. Alternatives like ceramic‑coated, stainless‑steel, cast‑iron, or carbon‑steel pans don’t contain PFAS and can deliver reliable non-stick performance with proper technique
As Simply Recipes summarized: “It is safest to replace any nonstick cookware when the coating is damaged, particularly if it was made before 2015”
Community Insights
Reddit threads and social media echo this advice. One user in r/cookware highlighted the severity:
“Researchers found just one five centimeter scratch… released up to 2.3 million microplastics.”
Others voiced a shift toward traditional cookware:
“You’re better off… stainless steel and carbon steel.”

Collectively, these voices reinforce official recommendations: when non-stick pans are compromised, it’s time to replace.
Final Takeaway
The study’s findings are a wake-up call for anyone using non-stick cookware:
- Surface scratches matter—they can seed food with thousands or even millions of plastic particles.
- PFAS persistence in the body and environment poses long-term health risks.
- Cautious use—protect the coating, avoid overheating, and discard damaged non-stick pans.
- Safer alternatives are available and effective with correct cooking methods.
While non-stick pans offer convenience, this study underscores a hidden trade-off. Scratches can open a pathway for toxic particles and PFAS to enter food—and ultimately, your body. If you value health and avoid exposure to “forever chemicals,” adopting PFAS-free cookware like ceramic, cast iron, or stainless steel is a wise choice.
Conclusion
The recent study serves as a powerful reminder that the convenience of non-stick cookware may come at a significant health cost if not used carefully. Scratches on Teflon-coated surfaces can release alarming quantities of microplastics and toxic PFAS chemicals into food, with potentially serious consequences for long-term health. As scientific evidence grows, consumers are encouraged to take proactive steps: avoid using damaged pans, adopt gentler cooking habits, and consider safer, PFAS-free alternatives. Ultimately, safeguarding your health may begin with something as simple as choosing the right pan.
