Non-stick cookware (PTFE-coated) — food safety profile

High risk

Cookware coated with polytetrafluoroethylene (PTFE) — marketed as Teflon (DuPont/Chemours) and many generic equivalents — to create a low-friction, food-release surface.

What is this product?

Cookware coated with polytetrafluoroethylene (PTFE) — marketed as Teflon (DuPont/Chemours) and many generic equivalents — to create a low-friction, food-release surface. Found in frying pans, saucepans, woks, griddles, electric skillets, and bakeware. The PTFE coating is applied over a base of aluminum (most common), stainless steel, or cast aluminum.

Who's most at risk

  • Pregnant Women — Fetal exposure via placental transfer; developing endocrine systems of fetus
  • Children — Higher food-to-body-weight ratio, developing organ systems

How to use it more safely

  • Use only on low to medium heat (below 500°F/260°C)
  • Use wooden, silicone, or plastic utensils only
  • Ensure adequate kitchen ventilation during cooking
  • Hand wash gently; avoid abrasive scrubbers and dishwashers

Red flags — when to walk away

  • Scratched, flaking, or peeling coating — Damaged PTFE releases particles into food. The particles themselves are likely biologically inert, but coating degradation also signals reduced thermal protection of the underlying metal.
  • Smoking or strong odor on high heat — Pan has exceeded 260°C and PTFE pyrolysis is beginning. Toxic fumes are being released.
  • Unbranded 'non-stick' at very low price points — Cheap non-stick coatings may use thinner application, inferior bonding, and may degrade faster.
  • 'PFOA-free' label without further certification — PFOA was phased out of PTFE manufacturing in the US by 2013. 'PFOA-free' is the minimum expected standard, not a premium safety feature. It does not mean PFAS-free.

Green flags — what to look for

  • Ceramic or stainless cooking surface — No PTFE; no PFAS in the cooking surface.
  • PFAS-free verified (third-party tested) — Independent verification that the coating contains no PFAS compounds.

Safer alternatives

  • Ceramic-coated cookware — Non-toxic, inert coating; safer at higher temperatures
  • Stainless steel cookware — Durable, no coating degradation; no chemical concerns
  • Cast iron cookware — Toxin-free; naturally non-stick when seasoned properly
