You scratched the base of your pan with a metal spatula. Ever since, you see the black line every time you cook, and you've already searched the question at 11pm.
A lot of pages answer it by frightening you, usually to sell you something. Let's do it differently.
What is known
PTFE — the material used in non-stick coatings — is considered stable at normal cooking temperatures. The small particles that come off a scratched coating are generally described as inert: they are not thought to be absorbed by the body.
PFOA, a compound once used in manufacturing these coatings, has been subject to restrictions and progressively removed from industrial processes. Most pans sold today carry a “PFOA-free” label.
The documented issue is overheating an empty pan. A non-stick coating taken very high in an empty pan left on the heat can give off fumes. This is well known to bird owners, whose animals are particularly sensitive to them. Never preheat a non-stick pan empty on high heat.
For an authoritative answer about your own situation, check the publications of your country's food safety agency rather than a blog — including this one.
What should actually decide it
The health question isn't the right question. The right one is more down to earth: a scratched pan no longer does the job you bought it for.
A coating is a layer added on top of metal. Layers wear. And as it wears, you start cooking around it without noticing:
- You turn the heat down to protect it — and on low heat meat never sears. It releases water, the water boils, and you get grey meat in a grey liquid.
- You add more fat to compensate.
- You give up metal utensils, the dishwasher, the oven.
You're not cooking any more: you're protecting a pan. And two or three years later you buy another one. Three pans in six years, the same story each time.
So do you bin it?
Not necessarily, not yet. A lightly scratched non-stick is still fine for what it does best: scrambled eggs, omelettes, pancakes, gentle cooking. Keep it for that.
But stop asking it for what it can no longer do: searing, browning, going in the oven, taking high heat. For that half of your cooking, you need a material with no layer on it.
What stainless changes
304 stainless steel has no coating. Nothing to scratch, nothing to chip, no coating to replace in two years. Metal utensils, oven, dishwasher, scouring pad: it doesn't care.
We own the downside: stainless asks you for two minutes of learning. It sticks when it's cold and it stops sticking when it's hot. It all comes down to the water drop test and the two-minute rule — two rules, one page.
