Teflon, the brand name for polytetrafluoroethylene (PTFE), was discovered in 1938 and quickly became a household staple because of its nonstick convenience. Eggs slid off pans, cleanup was easy, and it was marketed as a modern kitchen breakthrough (The Kitchn).

But research over decades has shown that the chemicals used to make Teflon, particularly perfluorooctanoic acid (PFOA), raise serious health and environmental concerns.

The Problems With Teflon and PFOA

For decades, PFOA was a key ingredient in the production of Teflon. It belongs to a group of chemicals often called “forever chemicals” because they don’t break down in the body or the environment (EWG).

Scientific studies and investigations—including those highlighted in The Devil We Know documentary—have linked PFOA exposure to:

  • Cancer risks
  • Thyroid disease
  • Reproductive issues
  • Immune system problems

Even though PFOA was phased out of U.S. production in 2015, research shows most Americans still have traces of it in their bloodstreams (EWG).

Beginning in 2026, many U.S. states have passed laws banning the sale and distribution of cookware containing PFAS.

Overheating Risks in Everyday Cooking

PTFE itself (the coating in Teflon pans) can become unstable at high heat. When cookware coated with Teflon is overheated beyond about 500°F (260°C), the surface can break down and release toxic fumes (The Kitchn).

These fumes can cause “polymer fume fever” in humans—a temporary, flu-like illness. They are also fatal to pet birds, which are highly sensitive to airborne toxins.

Why Safer Cookware Matters

The story of Teflon isn’t just about nonstick pans—it’s about transparency, safety, and making informed choices in the kitchen. As consumers, knowing the risks empowers us to choose alternatives that won’t compromise health.

At DaTerra Cucina, we believe cookware should support your well-being. That means creating pans without harmful coatings, so you can cook with confidence, flavor, and peace of mind.
