What to know about PFOS, PFOA and other pan coatings
Are the coatings on your saucepans and air fryer drawer safe? Here’s all you need to know to cook with confidence
Non-stick coatings for pans and kitchen gadgets keep food from sticking and certainly make clean up easier. But there’s been publicity around the dangers of some materials used, with “forever chemical” saucepan coatings and inner components of air fryers under scrutiny from concerned cooks.
What are PFOS and PFOA
Let’s start with the science: Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are both in the group of synthetic chemicals known as polyfluoroalkyl substances, or PFAS.
They have been used in all sorts of products because they have water and stain repellent properties - in simple terms, they’re what keep the coatings on some non-stick pans ‘slippy’.
PFOA coatings were banned in the UK in 2005 because of concerns about toxicity, with research showing the release of microplastics during use could contribute to health issues such as low birth weight, hormonal issues and an increased risk of some forms of cancer.
Since July 2020 the level of PFOS in production and in end products is restricted under EU Regulations.

So, it goes without saying that older pans lurking at the back of the cupboard - especially those which have been damaged, scored or have flaking to their base - should be destined for the dump immediately.
Don’t panic - your weekend fry up is safe. Today’s non-stick pans which are often coated in Teflon (the brand name for synthetic fluoropolymer PTFE) and have been found safe to use under normal conditions. The trick is to know how to use pans correctly as there are potential dangers with sustained use over 260 degrees Celsius. In these extreme temperatures, coatings can break down causing chemicals to be released.
What are PFAS chemicals?
Non-stick materials used in the market at present must comply with standards set by the Office For Product Safety and Standards in the UK, as well as with European legislation.
Are air fryers safe?
Let’s not forget the trays in air fryers, which can feature a variety of non-stick coatings. Always buy a well-known brand to ensure they comply with safety standards and if you prefer to avoid non-stick PTFE coatings, many of our favourite air fryers fit the bill. For example, Ninja’s range of air fryers feature ceramic-coated trays, or the Breville Halo Rotisserie air fryer oven has stainless steel inner shelves.
Other types of pan coatings
If you’d rather pans that don’t use ‘non-stick’ coatings , there are plenty of alternatives that offer efficient heat distribution and easy clean up.
Ceramic non stick
Ceramic non-stick pans are great for frying and general cooking with a smooth-as-silk ceramic coating that’s a pleasure to cook with. Some cooks appreciate the lighter colour of some models’ interiors as it can be easier to gauge levels of browning. And most ceramic pans can rival Teflon’s slip-and-slide non-stick qualities. Always use silicon and wooden utensils to prevent scoring - metal spoons can leave traces and wear down the coating..
Cast iron
Any carnivore will tell you there’s nothing like cast iron to get the perfect crust on a steak while retaining the juiciness of the meat. But treat your cast iron skillet well by seasoning it regularly and you’ll find it’s a great all-round workhorse in the kitchen, with surprisingly non-stick qualities. Although heavy at times, they’re also superb for one-pot dishes served at the table as they retain heat well.
Stainless steel
A bright stainless steel pan heats evenly and quickly while lasting the course in the busiest of kitchens. At the pricey end of the range come top-quality, bonded tri-ply stainless steel pans that cook evenly, thanks to an aluminium core that helps distribute heat efficiently. Choose a pan with handles in the same material and it’s good for hob-to-oven use too, at searing temperatures that wouldn’t be safe for Teflon models.
Aluminium pans
Aluminium may not have the staying power of some of the other choices here. Although fabulous for an even fry, for example, the cheaper models can be prone to warp over time. It’s more commonly used as an inner material for pans with other coatings as its heat distribution is impressive.
Carbon steel pans
Carbon steel pans are made from a combination of steel and cast iron to ensure sturdiness and even cooking results. Most require regular seasoning to ensure acceptable levels of ‘non-stickiness’ but they can be inexpensive, hardwearing and great for even results.
