Is Teflon safe, and should you throw out your Teflon pans?

Are you worried about the safety of your cookware? A recent study found that cooking with Teflon may cause a slew of health issues. According to a study released, there have been “hundreds” of complaints about fumes from overheated Teflon frying pans and pots. The fumes can cause flu-like symptoms such as headaches, nausea, and vomiting. As a result, many are turning away from using Teflon products altogether to avoid any associated risk. This blog post will explore what you should know about your favorite kitchen cookware and help you decide if you should continue using them in your home cooking routine. Read on to find out more!


What is Teflon?

Before we delve deeper into the safety of your cookware, let’s first understand what Teflon is. Teflon is the trade name for polytetrafluoroethylene (PTFE). This synthetic polymer began as a NASA invention to protect metal surfaces from corrosion. The material’s original use was for gasoline tanks but has been used outside aerospace applications due to its durability and nonstick properties.

Its characteristic fluorochemical layers make Teflon more flame retardant than other materials such as ceramic or steel. 


Why is Teflon used in cookware?

There are several reasons why Teflon is used in cookware:

  1. It provides a nonstick surface for frying pans and other cooking utensils. It prevents coagulation of fats during high temperatures, saving food from sticking and burning during cooking.
  2. It has very high heat conductivity, and it’s non-reactive. This means that nothing sticks to the cookware, and they don’t produce any unwanted flavors to your food.
  3. Teflon is an excellent thermal and chemical insulator that prevents food from cooking unevenly, so you always have a nice golden brown skin on your meats.
  4. It can also withstand high temperatures without breaking down and spilling all over the stovetop because of its durability!

Is Teflon toxic/harmful?

Now let’s address the elephant in the room – is Teflon bad for you? Teflon is a safe and relatively stable compound that withstands high temperatures. But, at temperatures above 570°F (300 °C), Teflon coatings on nonstick cookware start to break down. The toxic chemicals released into the air and inhaling these fumes may lead to Polymer Fume Fever, also known as “Teflonsyndrom.”

That said, it doesn’t mean that Teflon cookware is not safe, and they are certainly not toxic as long as we follow some basic precautions. In essence, avoid cooking at a temperature above 570°F (300 °C) and avoid inhaling any fumes released. Here are some tips to keep in mind:

  1. Avoid preheating an empty pan as doing so will cause it to reach high temperature within a short time.
  2. Avoid broiling as it would exceed the recommended temperature for the usage of nonstick cookware.
  3. Clear any fumes while cooking. Opening up a window will help to improve ventilation; alternatively, you can turn on an exhaust fan to absorb the fume.

Some misconceptions mislead many into thinking Teflon pans are toxic. However, concerns over toxins have to do with another synthetic chemical compound – Perfluorooctanoic acid (PFOA). The chemical PFOA was once used in the process of making Teflon. It is potentially a health concern as it can stay in the human body for a prolonged period. Even though PFOA is essentially burned off from the final product during the process, it has been replaced with a safer alternative in all Teflon products since 2013. This is due to growing evidence linking it to an increased risk for cancer among humans. 

While the international chemical regulators unanimously approved a global ban on PFOA use, Teflon is certainly not banned.


Are scratched Teflon pans dangerous?

While Teflon cookware is nonstick, they are not scratch-proof; the Teflon coating can chip off when sharp-edged utensils are used. However, scratches on Teflon pans are not dangerous; even if some of the coatings end up in your food, they will most likely just pass through the body when ingested. Moreover, the Public Health Authorities in Europe and the United States have demonstrated that Teflon is an inert substance with no effect on health, even in the case of ingestion. These authorities have confirmed the health safety of PTFE coatings in cooking utensils. So, don’t panic if you accidentally ate a piece of coating.


Should I throw out my Teflon pans?

If we follow the aforementioned best practices, Teflon pans have no health concerns, and scratches are harmless, so you do not have to throw them out. However, if the pan is damaged, it would reduce the nonstick properties and affect the efficacy of cooking. In that case, you may want to replace them.


Teflon alternative cookware/ what replaced Teflon?

  • Stainless steel: Stainless steel is excellent for sautéing and browning food. It is durable and scratch-resistant. It’s also dishwasher safe, making it easy to clean.
  • Cast-iron cookware: Cast iron is a long-lasting, versatile cooking vessel that can withstand high heat. It also maintains its nonstick surface over time and cleans easily when you want to switch up your dishes!
  • Stoneware: For thousands of years, stoneware has been used for cooking and baking. It can be heated evenly without burning the food on its surface because it’s nonstick once properly seasoned and is immune to scratches and knife marks!
  • Ceramic cookware: Ceramic cookware has excellent nonstick properties, but the downside is it scratches pretty easily if you aren’t careful. It would be best to be more cautious when doing the cleaning because they are not as sturdy.
  • Silicone cookware: Silicone is an excellent alternative to metal and wooden utensils because it’s heat-resistant and can withstand high temperatures. However, it doesn’t stand up well to direct heat, so it’s more commonly used in bakeware and utensils instead of pots and pans.

Final thoughts

The dangers of Teflon are debatable. Some people think it’s excellent for cookware because it’s heat-resistant and nonstick. Others are concerned about its safety because it is brittle when scratched or overheated (which can release toxic fumes), and it’s not worth taking the chance. They would instead replace their nonstick cookware with something else entirely. Ultimately, the decision to keep old Teflon frying pans depends on whether you think any health risks outweigh the benefits of its nonstick property.
