In recent months, there has been a noticeable rise in cases of “Teflon flu” in the United States. This condition, also known as polymer fume fever, has raised concerns among health officials and the general public. This article will explore what Teflon flu is, its symptoms, causes, and what you can do to protect yourself.

What is Teflon Flu?
Teflon flu, or polymer fume fever, is a condition caused by inhaling fumes from overheated polytetrafluoroethylene (PTFE), commonly known as Teflon. PTFE is used in nonstick cookware and other products. When heated above 500°F (260°C), Teflon releases toxic fumes that can lead to flu-like symptoms.

Symptoms of Teflon Flu
The symptoms of Teflon flu are similar to those of the common flu and typically appear within a few hours of exposure. They include:

Fever
Chills
Headache
Sore throat
Muscle aches
Dry cough
These symptoms are usually temporary and subside within 24 to 48 hours. However, severe exposure can lead to more serious health issues, particularly in individuals with pre-existing respiratory conditions.

Causes and Risk Factors
Teflon flu is caused by inhaling fumes from overheated PTFE-coated cookware. The risk of exposure increases when:

Cooking at high temperatures (over 500°F/260°C)
Using damaged or scratched nonstick cookware
Poor kitchen ventilation
Birds are particularly sensitive to PTFE fumes and can suffer fatal consequences from exposure, which underscores the potential danger to humans.

Recent Rise in Cases
The recent increase in Teflon flu cases in the US can be attributed to several factors:

Increased use of nonstick cookware during the COVID-19 pandemic as more people cooked at home
Lack of awareness about the dangers of overheating nonstick pans
Worn-out cookware being used longer due to economic reasons
Prevention and Safety Tips
To reduce the risk of Teflon flu, follow these safety tips:

Avoid Overheating Cookware: Do not preheat empty nonstick pans, and avoid cooking at temperatures above medium-high.
Use Proper Ventilation: Ensure your kitchen is well-ventilated while cooking. Use an exhaust fan or open windows to disperse fumes.
Replace Damaged Cookware: Discard nonstick cookware that is scratched or damaged.
Consider Alternatives: Use alternative cookware such as stainless steel, cast iron, or ceramic, which do not emit toxic fumes.

Teflon flu, though generally mild and short-lived, can be unpleasant and potentially harmful. By understanding the risks and taking simple precautions, you can protect yourself and your loved ones from this condition. Stay informed and cook safely to avoid the hazards associated with overheated nonstick cookware.
