MDLinx‘Teflon Flu’ on the Rise

Increasing Incidence of Polymer Fume Fever Linked to Common Cookware Raises Concerns About Household Chemical Exposure

Recent data from America’s Poison Centers reveals a significant uptick in cases of “Teflon flu,” a condition caused by inhaling fumes from overheated nonstick cookware. With 265 suspected cases reported in 2023 alone, this trend highlights the potential health risks associated with common household items.

Key Points:

• Teflon flu, also known as polymer fume fever, results from inhaling fumes released when polytetrafluoroethylene (PTFE) cookware is overheated to 500-650°F.
• Symptoms include chest tightness, dry cough, fever, malaise, and shortness of breath, often mimicking a common cold.
• Onset of symptoms typically occurs within hours of exposure and usually resolves within a few days.
• Severe cases may rarely lead to leukocytosis and pulmonary edema.
• Risk reduction strategies include:
  • Adding water, broth, or oil to pans before cooking
  • Avoiding heating empty nonstick pans
  • Ensuring proper kitchen ventilation
  • Using a kitchen fume hood
  • Opening windows and using fans while cooking
• Alternative cooking methods to reduce risk include:
  • Using stainless steel cookware with proper preheating techniques
  • Roasting food in the oven
  • Cooking in the microwave
  • Grilling outdoors
• Healthcare providers should consider inquiring about cooking habits when patients present with persistent, unexplained respiratory symptoms.
• The first cases of polymer fume fever were recorded in 1951 from occupational exposures.
• Immediate contact with poison control is recommended if Teflon flu is suspected.

Dr. Roy Plunkett discovered PTFE — Teflon — in 1938 while trying to create a refrigerant.
