The health risks of PFAS exposure
Why PFOA-free does not mean PFAS-free
The non-stick pan is one of the most convenient inventions in the modern kitchen. It is also one of the most chemically complex surfaces your food regularly comes into contact with.
Most non-stick coatings belong to the PFAS family, per and polyfluoroalkyl substances, the same class of forever chemicals found in waterproof clothing, food packaging, firefighting foam and, as the UK Government confirmed in February 2026, in 88% of surface water samples tested across England.
PFAS do not break down naturally in the environment or in the human body. They accumulate over time, in wildlife, in water supplies and in human tissue. The question for your kitchen is not whether PFAS are in your non-stick pan. They almost certainly are. The question is how much is getting into your food and what you can do about it.
What Is PTFE and Why Does It Matter
The coating on most non-stick pans is called PTFE, polytetrafluoroethylene, best known by the brand name Teflon. PTFE is a polymer form of PFAS. It was first developed in the 1940s and became a kitchen staple by the 1960s.
Research by the Ecology Center found that 79% of tested non-stick cooking pans were coated with PTFE. Many of the remaining 21% either contained other PFAS compounds or made claims on their packaging that were misleading, as we cover below.
PFAS are called forever chemicals because they do not break down naturally in the environment or in the body. They accumulate over time. Some are eliminated slowly over years. Others persist for decades. The most concerning in terms of human health effects are those that bioaccumulate, meaning they build up in tissue faster than the body can eliminate them.
The Health Risks of PFAS Exposure
The body of evidence linking PFAS exposure to human health effects has grown substantially over the past decade. Research published across multiple peer reviewed journals has associated PFAS with:
Multiple studies have linked higher PFAS blood levels to reduced fertility in both men and women, earlier menopause, reduced birth weight and disruption to fetal development. PFAS have been detected in human placentas, amniotic fluid and breastmilk.
PFAS interfere with thyroid hormone synthesis and transport. Thyroid hormones regulate metabolism, growth and development. Disruption during pregnancy and early childhood is associated with long term neurological effects.
A landmark study published in JAMA found that children with higher PFAS blood levels had significantly lower antibody concentrations following routine childhood vaccinations, in some cases falling below the threshold considered protective. This finding was a significant factor in the push for binding PFAS drinking water standards.
Higher occupational and environmental PFAS exposures have been associated with increased risk of kidney cancer, testicular cancer and certain other cancers, particularly in communities near PFAS manufacturing sites or contaminated water supplies.
PFAS exposure has been associated with elevated cholesterol, disrupted lipid metabolism and increased risk of non-alcoholic fatty liver disease.
Why PFOA-Free Does Not Mean PFAS-Free
This is the most important thing to understand about non-stick cookware labelling, and the most commonly misunderstood.
PFOA, perfluorooctanoic acid, is one specific PFAS compound that was historically used in the production of PTFE coatings. It was phased out of production in the United States in 2014 after studies clearly linked it to serious health risks. Since then virtually all non-stick cookware sold in the UK and US has been labelled PFOA-free.
Important: PFOA-free means the product was not made using PFOA. It does not mean the product is free of PFAS. A pan labelled PFOA-free can still have a PTFE coating, which is itself a PFAS compound. Research by the Ecology Center found that most pans labelled PFOA-free were coated with PTFE without disclosing that fact on the packaging.
Consumer Reports tested three non-stick pans making PFOA-free or PFAS-related claims. The two ceramic pans with PTFE-free labels contained none of the 96 PFAS compounds tested for. The pan with a PTFE coating and a PFOA-free label still contained PTFE.
The label to look for is PTFE-free, not PFOA-free. PTFE-free ceramic pans tested by Consumer Reports contained none of the 96 PFAS compounds tested.
Temperature and When the Risk Increases
PTFE coatings are considered relatively stable at low and medium cooking temperatures. The risk increases significantly as temperature rises.
Under normal cooking conditions the coating wears away gradually over time, and small particles enter food. Under high heat, particularly when a pan is left empty on a hot burner or heated above its rated temperature, the coating can break down more rapidly and release particles and fumes into the air above the cooking surface.
Scratched and worn non-stick pans represent a higher risk than new ones. A scratched surface releases particles more readily. If your non-stick pan is visibly worn, scratched or peeling, replacing it with a clean alternative is strongly advisable.
Practical note: Never preheat an empty non-stick pan. Never use metal utensils on non-stick surfaces. Never put non-stick pans in the dishwasher as it accelerates coating degradation. All three actions increase the rate at which PFAS particles enter your food or the air in your kitchen.
The Cleanest Alternatives
The good news is that the cleanest cookware alternatives perform excellently and in many cases outlast non-stick pans significantly.
Cast Iron
Naturally non-stick once properly seasoned, lasts a lifetime and adds trace amounts of dietary iron to food. Works on all hob types including induction. The heavier weight is the only genuine trade-off. A well-seasoned cast iron pan requires less oil than most people expect and is genuinely as non-stick as a coated pan for most cooking tasks.
Stainless Steel
Durable, non-reactive, performs at high heat and is dishwasher safe. Requires slightly more oil or fat to prevent sticking than non-stick coatings, but produces better caramelisation and browning which is often preferable for cooking quality.
Ceramic Coated — with one important caveat
Ceramic coated pans can be genuinely PFAS free when the coating is PTFE-free and independently tested. Consumer Reports found that ceramic pans with PTFE-free labels contained none of the 96 PFAS compounds they tested for.
The caveat is that the term ceramic is sometimes used loosely in marketing. Look specifically for PTFE-free on the label, and prefer brands that publish independent third party testing data for PFAS. The word ceramic alone is not sufficient.
Swap your cookware
Find cast iron pans, stainless steel cookware and PTFE-free ceramic alternatives on Amazon.
Shop PFAS-free cookware on Amazon →The pan you cook with several times a week, over years and decades, is one of the most consistent points of chemical contact in your daily life. It does not require a dramatic overhaul. When your current non-stick pan wears out or shows signs of scratching, replace it with cast iron, stainless steel or a verified PTFE-free ceramic alternative.
One pan at a time is enough.
