Rise in Teflon Flu Cases: Why You Should Be Careful Using Nonstick Cookware Coatings

Polymer fume fever, also known as “Teflon flu,” is an increasingly reported condition linked to the use of nonstick cookware. This illness results from inhaling fumes released when polytetrafluoroethylene (PTFE), a chemical commonly used in nonstick coatings, is overheated.¹ With a notable rise in reported cases, it’s crucial to understand the risks and take appropriate precautions when using nonstick cookware.

What is Teflon Flu?

Teflon flu is a set of flu-like symptoms caused by inhaling fumes from overheated nonstick pans. These pans, often coated with PTFE, release toxic particles when exposed to temperatures above 500 degrees Fahrenheit (260 degrees Celsius).

Symptoms of Teflon flu include fever, chills, coughing, difficulty breathing, headaches, nausea, and fatigue. These symptoms typically appear within a few hours of exposure and generally resolve within a day or two without treatment​.

Recent Increase in Cases in the US

In 2023, there were 267 suspected cases of polymer fume fever reported in the United States, the highest number since 2000.² Over the past two decades, more than 3,600 cases have been recorded by U.S. poison centers. This rise highlights the importance of proper usage and awareness of nonstick cookware risks​.

Safety Precautions

To reduce the risk of Teflon flu and other health issues, consider the following safety measures:

1. Replace Old or Damaged Cookware: Discard nonstick cookware that shows signs of wear or is more than three to five years old.
2. Avoid High Temperatures: Do not preheat nonstick pans on high heat or use them for cooking methods that require temperatures above 500 degrees Fahrenheit. Always add food, butter, or oil before heating.
3. Ensure Proper Ventilation: Use exhaust fans and open windows while cooking to prevent inhaling toxic fumes.
4. Alternative Cookware Options: Consider using cast iron, stainless steel, ceramic, or silicone cookware to avoid the risks associated with nonstick coatings​.

Expert Opinions and Manufacturer Guidelines

Experts advise careful use of nonstick cookware to prevent health risks. Nonstick pans should never be preheated empty, and cooking should always be done on medium to low heat. Manufacturers such as Chemours and Calphalon emphasize following usage guidelines to ensure safety. Additionally, it’s recommended to use wood, silicone, or nylon utensils to prevent scratches on the nonstick surface, which can lead to the release of microplastics into food​.

Conclusion

The rise in Teflon flu cases underscores the need for careful use of nonstick cookware. By following safety precautions and staying informed about the potential risks, you can minimize exposure to harmful fumes and ensure a healthier cooking environment. For those seeking alternatives, options such as cast iron, stainless steel, and ceramic cookware provide safe and effective solutions.
