Teflon™ non-stick pans have been around for over 50 years. They are popular because of their non-stick coating, which allows food to slip right off the pan. However, there are concerns about the safety of Teflon pans, especially regarding the release of toxic chemicals when heated above 500°F (260°C). While modern Teflon products no longer contain PFOA, they still contain PTFE, which can release toxic fumes when heated above 570°F. Some people recommend avoiding Teflon altogether and opting for alternative materials like stainless steel, cast iron, or ceramic.
| Characteristics | Values |
|---|---|
| Safety | Teflon is considered safe for everyday home cooking, but only if it is not heated above 500°F (260°C). Heating above this temperature releases toxic fumes, which can cause polymer fume fever or "Teflon flu". |
| Health Concerns | Exposure to high levels of PFOA may increase the risk of cancer. Teflon coatings may also contain PTFE, which can release toxic fumes when heated above 570°F (300°C). |
| Durability | Teflon coatings can withstand metal utensils and minor scratches without affecting performance. However, excessive scratches, peeling, flaking, and chipping indicate that the cookware needs to be replaced. |
| Dishwasher Safe | Teflon-coated pans from reputable manufacturers can be put in the dishwasher, but it is recommended to follow the manufacturer's care instructions. |
| Alternatives | Alternatives to Teflon include stainless steel, ceramic, cast iron, and carbon steel. Ceramic is considered safer than Teflon but is less durable and more prone to scratching. |

What You'll Learn
Teflon pans are still widely available
Teflon is a brand name for a non-stick coating that has been used in cookware for over 50 years. The coating is made from a chemical compound called PTFE (polytetrafluoroethylene). PTFE is also known as C8, which is harmful to human health and the environment.
In 2013, manufacturers stopped using PFOA (perfluorooctanoic acid) in the production of Teflon. PFOA is a chemical that was found in the blood of 98% of people in the United States, and it was linked to an increased risk of cancer. However, Teflon products manufactured before 2013 likely still contain PFOA.
Today, Teflon is generally considered safe for everyday home cooking when used as directed. It can withstand temperatures of up to 500°F (260°C), which is well above the temperatures required for boiling, frying, and baking. However, at temperatures above 500°F (or 570°F, according to some sources), Teflon coatings begin to break down, releasing toxic fumes. These fumes can cause a condition called polymer fume fever or "Teflon flu," which causes temporary flu-like symptoms.
There are alternative options to Teflon pans, such as stainless steel, cast iron, carbon steel, and ceramic. Ceramic cookware is a popular alternative as it is PFOA- and PTFE-free, but it tends to be less durable and can scratch and chip over time. Stainless steel is also a good option, but it is not inherently non-stick and can be prone to discolouration. Cast iron is durable, long-lasting, and non-toxic, but it is heavier than other options and not ideal for cooking acidic foods. Carbon steel pans are not inherently non-stick, but they can become non-stick over time with use.

Safety concerns about Teflon
Teflon is a brand name for a chemical coating called polytetrafluoroethylene (PTFE), a type of plastic sprayed on items and baked to create a nonstick, waterproof, non-corrosive, and non-reactive surface. While Teflon has been approved by the FDA and is still used in a number of everyday products, there are several safety concerns associated with its use.
Firstly, there are concerns about the health risks of PTFE, as it has been linked to various serious health conditions. When exposed to high heat, Teflon releases toxic chemicals called perfluorinated compounds (PFCs) into the air. Inhaling these fumes can lead to polymer fume fever, also known as the Teflon flu. Additionally, there are worries about the potential impact of PTFE particles flaking off from cookware and finding their way into food. While these particles are considered safe even if ingested, some groups remain concerned about the potential health impact, especially given that PTFE is a synthetic chemical that will not degrade for millions of years.
Secondly, Teflon coatings contain perfluorooctanoic acid (PFOA), a chemical found to produce higher rates of kidney and testicular cancer, ulcerative colitis, thyroid disease, and other conditions. While the use of PFOA in manufacturing Teflon-coated cookware has been stopped since 2013, a 1999 study found that 98% of people in the United States had PFOA in their blood due to environmental exposure. As a result, the US EPA aimed to eliminate PFOA usage by 2015.
Thirdly, Teflon coating fumes are deadly to birds, as their respiratory systems are more fragile than humans. Exposure to these fumes can cause birds' lungs to hemorrhage and fill with fluid, leading to suffocation and death.
Finally, there are environmental concerns regarding the use of Teflon. As PTFE is a synthetic chemical that does not easily degrade, it can persist in the environment for long periods. Additionally, replacement chemicals for PFOA, such as GenX, have been found in residential water, and families have no way of knowing their level of exposure to these chemicals.
Given these safety concerns, some individuals opt for alternative cookware options, such as stainless steel, cast iron, carbon steel, or ceramic.

Alternatives to Teflon
Teflon pans are popular because they are non-stick, require little to no maintenance, and are durable. However, concerns have been raised about the safety of using Teflon pans due to the presence of PFOA, a chemical that was previously used in the manufacturing of Teflon-coated cookware. While the use of PFOA has been discontinued, some people still prefer to use alternative cookware due to the potential health risks associated with Teflon. Here are some alternatives to Teflon pans:
Carbon Steel Pans
Carbon steel pans are a popular alternative to Teflon as they are durable, inexpensive, and excellent at searing. They can also become non-stick with use and proper seasoning. However, they require hand washing and may need effort and commitment to maintain.
Ceramic Coated Pans
Ceramic-coated pans are another option for those seeking a non-stick alternative to Teflon. While they may not be as durable as Teflon pans and might degrade quicker, they are still a viable choice. Some ceramic pans now come with diamond dust to increase their strength and longevity.
Cast Iron Pans
Cast iron pans are a traditional cookware option that can be used as an alternative to Teflon. They are durable and can be made non-stick with proper seasoning. However, they may require more maintenance than other options.
Stainless Steel Pans
Stainless steel pans are a good alternative for those seeking a non-Teflon option. They are suitable for cooking various dishes, but they may not be the best choice for cooking sticky foods like eggs without the use of oil or butter.
It is important to note that while these alternatives exist, some people choose to continue using Teflon pans as they are convenient and widely available. Additionally, the potential health risks associated with Teflon pans are still being debated, with some sources claiming that Teflon is safe for human use.

How to care for your Teflon pans
Teflon is a brand name for a chemical coating called polytetrafluoroethylene (PTFE). It is still used in most non-stick cookware. While Teflon itself is generally safe, a chemical called PFOA, previously used in the manufacturing of Teflon-coated cookware, has been linked to an increased risk of cancer. However, the use of PFOA has been discontinued since 2013.
Avoid High Heat
High heat can damage the non-stick coating over time. Always use low or medium heat when cooking with Teflon pans. At extremely high temperatures, usually around 600 degrees Fahrenheit (300 degrees Celsius or 570 degrees Fahrenheit, according to another source), Teflon can release potentially dangerous fumes.
Use Proper Utensils
Avoid using metal utensils with non-stick pans as they can scratch or damage the coating. Wooden spoons, silicone utensils, and rubber or wooden spatulas are safer options.
Preheat the Pan
Always preheat your pan before adding ingredients. Add oil or butter and distribute it evenly while the pan is still cool. This will help prevent sticking and improve the integrity of your ingredients.
Use the Right Type of Oil
Oils with a high smoke point, such as grapeseed, sesame, or avocado oil, are better choices than those with a low smoke point, like extra virgin olive oil (EVOO). Low smoke point oils burn more easily and can decrease the pan's non-stick properties.
Avoid Cooking Sprays
Cooking sprays can damage your non-stick pan. They burn at a lower temperature than the non-stick coating and leave behind a residue that builds up over time, negatively affecting the non-stick surface.
Proper Cleaning and Storage
Always allow the pan to cool before washing it. Submerging a hot pan in cold water or running cool water over it can warp the pan. Hand washing is recommended over using a dishwasher, as the hot temperatures and detergents in dishwashers can break down the non-stick surface. Wash the pan with hot, soapy water and a sponge, dishcloth, or cleaning pads labelled safe for non-stick cookware.
Be Mindful of Food Preparation
Never cut or stab food with a knife in the pan, as this can chip the coating. Also, avoid deglazing, searing, or browning techniques that involve adding liquid to the pan while it is still hot. Instead, preheat the pan, add oil, and then your ingredients, and only then add liquid to the pan.
Keep Your Stove Level
Ensure that your stove is level to prevent liquid from pooling in one area, which can lead to uneven heating and potential warping of the pan.
Regular Maintenance
Inspect your pan regularly for any signs of wear and tear. If the non-stick coating starts to flake or chip, it may be time to replace the pan. Proper care and maintenance can extend the lifespan of your Teflon pans, but they will eventually need to be replaced.

Teflon pans and cancer risk
Teflon is a brand name for a synthetic chemical called polytetrafluoroethylene (PTFE). It is used to coat various products, including non-stick pans, because it is waterproof, reduces friction, and creates a non-stick surface.
The concern over Teflon cookware and cancer risk is related to perfluorooctanoic acid (PFOA), a human-made chemical previously used in the manufacturing process of Teflon. PFOA has been found to cause adverse health outcomes in humans if consumed or absorbed. Studies have also suggested a link between exposure to PFOA and certain types of cancer, such as testicular and kidney cancer. However, it is important to note that PFOA has not been used in the production of Teflon since 2013.
While there is some research suggesting a link between PFOA and cancer, there is no proven link between Teflon and cancer. The American Cancer Society and other health agencies have stated that there are no proven risks to humans from using cookware coated with Teflon. Additionally, particles from Teflon non-stick coatings are not harmful, even if ingested.
It is worth mentioning that heating Teflon-coated pans to extremely high temperatures can lead to flu-like symptoms such as headaches, chills, and fever. At temperatures above 280°C (536°F), PTFE-coated surfaces begin to emit chemical byproducts that can be harmful. Therefore, it is recommended to avoid overheating Teflon-coated pans and always follow the manufacturer's care instructions.
