Non-stick pans are a handy kitchen tool, but they don't last forever. Scratches and chips can form over time, and it's important to know when to replace them. Non-stick pans are coated with polytetrafluoroethylene (PTFE), commonly known by the brand name Teflon, which is a per- and polyfluoroalkyl substance (PFAS). These chemicals are known as forever chemicals because they take a long time to break down. While there is some debate about the health risks associated with scratched non-stick pans, multiple studies have found links between PFAS and various health issues, including liver problems, high blood pressure, and cancer. To avoid exposure to potentially toxic chemicals, it is recommended to replace non-stick cookware when the coating is damaged, especially if it was made before 2015. Safer alternatives to non-stick pans include cast iron, stainless steel, and carbon steel.
Characteristics and values of using a non-stick pan that's chipping
| Characteristics | Values |
|---|---|
| Safety | The non-stick coating on pans often contains PFAS (per- and polyfluoroalkyl substances), which are known as "forever chemicals" due to their longevity in the environment. When these pans are scratched or chipped, small particles containing PFAS can flake off into food, as shown in a 2022 study. Exposure to these particles may be linked to health issues such as liver problems, high blood pressure, and cancer. |
| Alternative materials | Safer alternatives to non-stick pans with PFAS include cast iron, stainless steel, and carbon steel. Ceramic-coated pans are another option, although their non-stick abilities may not last as long as traditional non-stick pans. |
| Maintenance | To prolong the life of non-stick pans, avoid using metal utensils, cooking spray, and dishwashers. Instead, opt for silicone or wood utensils, and hand wash the pans after allowing them to cool. |
| Replacement | If your non-stick pan is chipped, it is recommended to replace it, especially if it was manufactured before 2015. Fresh scratches and food starting to stick to the pan are also indicators that it's time for a replacement. |

Non-stick pans can release harmful chemicals when heated
Non-stick pans are popular due to their convenience and ease of use. However, concerns have been raised about the potential release of harmful chemicals when these pans are heated, especially if they are scratched or chipped.
The non-stick coating on these pans is often made from a chemical compound called PTFE (polytetrafluoroethylene), commonly known by the brand name Teflon. PTFE belongs to a group of chemicals known as PFAS (per- and polyfluoroalkyl substances), which are sometimes referred to as "forever chemicals" due to their persistence in the environment. Other commonly studied PFAS include PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid).
When non-stick pans are heated, especially when empty, they can release gases and particles that may be harmful. Studies have shown that these chemicals have been linked to various health issues in humans, including liver problems, high blood pressure, and certain types of cancer. Additionally, the fumes released from overheated non-stick pans can be deadly to pet birds.
If a non-stick pan is scratched or chipped, small particles of the coating may flake off into the food being cooked. A 2022 study found that scratched pans coated with PFAS released thousands to millions of microplastics and nanoplastics. Ingesting these particles may pose potential health risks, although the extent of the danger is still debated.
To minimise the risk of exposure to harmful chemicals, it is recommended to avoid using scratched or dented non-stick pans. Proper maintenance of non-stick pans is crucial, including avoiding metal utensils, using silicone or wood-based utensils, and hand-washing the pans instead of putting them in the dishwasher. Additionally, it is advised not to heat non-stick pans when empty, as this can lead to the release of toxic gases.

Scratches on non-stick pans can cause flakes in food
Non-stick pans are popular because they make cooking easier. However, they don't stay perfect forever and can get scratched or chipped. The non-stick coating on these pans is often made from a chemical compound known as PTFE (polytetrafluoroethylene) or under the brand name Teflon. Some brands use a ceramic nonstick coating instead, though it loses its non-stick abilities faster than Teflon.
When a non-stick pan is scratched or chipped, small particles of the coating can flake off into the food being prepared. A 2022 study found that scratched pans coated with these chemicals release thousands to millions of microplastics and nanoplastics. These flakes may or may not be harmful to humans. However, the chemicals used to create the non-stick coating, often PFAS (per- and polyfluoroalkyl substances), are known as "forever chemicals" because they take a long time to break down and have been linked to various health issues, including liver issues, high blood pressure, and some cancers.
To avoid exposure to potentially toxic chemicals, it is recommended to replace any non-stick cookware when the coating is damaged, especially if it was made before 2015. If your food starts to stick to the pan, it is also a sign that the surface is wearing down, and it is time to replace it. It is important to note that even newer models of non-stick cookware made in the United States may not be completely safe, as they can still release harmful chemicals if heated past 500°F.
To prolong the life of your non-stick pan and avoid scratches, it is recommended to avoid using metal utensils and putting the pan in the dishwasher. Instead, use silicone or wood-based utensils and always hand wash the pan after it has cooled down. Additionally, always use oil or butter when cooking, as you should never heat a non-stick pan without anything in it.
If you are concerned about the potential health risks associated with non-stick pans, you can consider switching to safer alternatives such as cast iron, stainless steel, or carbon steel pans. These pans do not use the same toxic chemicals and can provide a good non-stick surface when properly preheated.

Safer non-stick pan alternatives
Non-stick pans are popular due to their convenience and ease of use. However, they can become scratched or chipped over time, which can be a cause for concern. While the hazards posed by flaking pans are not greater than intact ones, it is still important to be cautious as small particles can flake off into food. Additionally, heating empty non-stick pans can release gases and particles that are toxic to birds and may be linked to health issues in humans.
If you're looking for safer alternatives to non-stick pans, here are some options to consider:
Ceramic-Coated Pans
Ceramic-coated pans are a popular alternative to traditional non-stick cookware. They offer a slick surface that generally doesn't require oil when cooking and are free from harmful chemicals like PFAS, PFOA, and PTFE. Brands like Caraway, Our Place, and Alva Cookware offer ceramic-coated options. Xtrema is another brand that offers pure ceramic cookware without any coatings or a metal core, making it one of the least toxic options available.
Stainless Steel
Stainless steel cookware is considered a safe and non-toxic option. It heats up quickly, cooks food evenly, and is easy to clean. All-Clad's D3 Everyday set is a popular choice in this category. Stainless steel is also affordable, making it a good starting point if you're transitioning from non-stick to steel.
Cast Iron
Cast iron pans are a traditional and durable option for cookware. They require proper preheating to create a non-stick surface, but they can handle high temperatures and sear food effectively. Cast iron skillets are a popular choice for cooking eggs, for example.
Carbon Steel
Carbon steel is another non-toxic option that performs similarly to cast iron. It requires a bit more oil before cooking and has some restrictions on cooking extremely acidic foods.
Titanium
Titanium is a naturally non-stick material that is both PFAS-free and coating-free. The Titanium Always Pan Pro is an example of this type of cookware, which has multiple layers of metal for impressive durability.
When choosing a non-stick pan alternative, it's important to prioritize your health and the safety of your food. These options offer non-stick or non-toxic properties without relying on potentially harmful chemicals. Remember to hand wash your pans and avoid overheating them to prolong their lifespan and maintain their safety.

How to clean and maintain non-stick pans
Non-stick pans are designed to prevent food from sticking to their surface, making cooking and cleaning convenient. However, they require special care to prevent their surface from scratching, peeling, or warping. Here are some tips to clean and maintain your non-stick pans:
Cleaning Non-Stick Pans:
Before cleaning, allow the pan to cool down completely. Then, rinse it with soap and warm water to remove leftover food particles. Use a sponge or washcloth to scrub the surface gently, and rinse again. Always dry the pan with a clean towel after washing.
For burnt food or stubborn residue, you can use one of two methods:
- Soak the pan in warm, soapy water for 10-20 minutes, then hand wash it again.
- Mix a small amount of baking soda with water to form a paste and apply it to the pan. Lightly scrub with a non-abrasive sponge, then rinse and dry as usual.
Maintaining Non-Stick Pans:
Avoid using metal utensils with non-stick pans as they can scratch the coating. Opt for wooden spoons or silicone utensils instead. Do not place empty pans on active burners, and avoid heating above 500 degrees Fahrenheit. Also, refrain from using aerosol cooking sprays as they can damage the non-stick coating over time.
It is important to note that once a non-stick pan is scratched or chipped, small particles can flake off into your food. While some claim that ingesting these flakes is not harmful, it is generally recommended to replace any non-stick cookware with a damaged coating, especially if it was manufactured before 2015.

How to identify if a non-stick pan is coated with PFAS
Non-stick pans are coated with a special type of slippery coating, which was once a type of PFAS (or "forever chemical") called perfluorooctanoic acid or PFOA. After safety concerns about PFOA arose, it was banned from cookware in Europe in 2008 and phased out in the United States in 2015.
The new non-stick cookware is made with a variety of coatings, including PEEK (a type of high-performance plastic), ceramic (often combined with a layer of silicon-derived polymer), and the most common, polytetrafluoroethylene (PTFE)—a polymer made with next-generation PFAS chemicals that are linked to the same issues as PFOA.
- Check the packaging: Look for pans that are labelled as "PTFE-free", as tested pans with this label were found to be free of PFAS. However, be cautious of other labels, such as ""PFOA-free", as these may not always be PFAS-free.
- Opt for uncoated pans: Choose pans made from cast iron, stainless steel, or carbon steel. These pans are unlikely to contain PFAS, although they may require more effort to prevent food from sticking and may be more challenging to clean.
- Consider ceramic-coated pans: Ceramic coatings offer a relatively non-stick surface without the toxic chemical load associated with PFAS. However, keep in mind that ceramic coatings are known for having shorter useful lifespans.
- Research the brand: Look into the specific brand and model of the non-stick pan you're considering. Some brands, such as Red Copper and Always, are known for their ceramic coatings and are said to be free of PTFE and PFOA.
- Test the pan: If you already own the pan, you can consider sending a sample of the coating for testing to identify the presence of PFAS chemicals. However, this option may be more costly and time-consuming.
It's important to note that even if a pan is labelled as "PFOA-free", it could still contain other PFAS chemicals. The best way to avoid exposure to PFAS is to choose uncoated pans or those with safer non-stick surfaces, such as ceramic coatings.
