THE LABEL FILES · Cookware
What's Actually in Your Cookware
The chemical that made nonstick pans nonstick is now a Group 1 human carcinogen, and it's still in your blood.
In 2023, PFOA, the 'forever chemical' that made nonstick coatings possible, was reclassified as a Group 1 human carcinogen, the same category as tobacco and asbestos. It was phased out of US production around 2015, but it never breaks down: it's in older pans, in the water, and in nearly everyone's blood. Cookware isn't an ingredient label, but the materials it's made of are chemistry you eat from every day.
Forever chemicals, then and now
PFOA is gone from new pans, but if your nonstick predates 2015, it's the one to retire. The replacements, GenX, PFBS and other PFAS, were sold as safer, and the EPA links them to the same liver, kidney, immune and developmental harms. It's a textbook 'regrettable substitution.' The EU is moving to restrict the entire PFAS class; the US has a patchwork of state cookware bans and no federal rule.
The PTFE truth, without the panic
An intact PTFE (Teflon) pan at normal cooking temperature is stable and inert, we won't pretend otherwise. The real risks are specific and avoidable: an empty pan overheated past 500°F releases fumes that sicken people and kill pet birds, and a scratched coating sheds particles into food. Don't preheat empty, skip metal utensils, and replace it when it's scratched. That's the honest user manual.
The cheap import problem, and the clean exit
The sharper danger is at the bottom of the market: unbranded imported glazed and aluminum-alloy cookware can leach lead and cadmium straight into food, and the FDA issued fresh enforcement alerts on leaded imports in 2025. There is no safe level of lead. The exit is simple and cheap: cast iron, stainless steel, or PFAS-free ceramic sidestep the entire problem. Sometimes the right answer is just better materials.
The teardowns
T-fal Classic Nonstick (PTFE coating) →
PTFE coating is stable at normal cooking heat, but an empty pan hits 391°C on a conventional burner in under 4 minutes, and that is where the chemistry changes.
GreenPan / Generic Ceramic Ceramic Nonstick Pan →
The PFAS-free pan that actually delivers on the claim, with a silica-based coating that wears faster than PTFE and may contain TiO₂ nanoparticles that brands don’t disclose.
(Unbranded import) Glazed / Aluminum-Alloy Pan →
Lead has no safe level. The FDA’s August 2025 enforcement alert named Hindalium/Hindolium aluminum alloy cookware specifically, and expanded the warning in November 2025.
