Potential Health Concerns
1. Release of toxic fumes at high temperatures
Non-stick surfaces, commonly found in cookware, are coated with a material known as polytetrafluoroethylene (PTFE), which is resistant to heat and provides the non-stick feature. While PTFE is generally safe to use at low to medium temperatures, it can release toxic fumes when heated above a certain temperature threshold (usually around 500°F or 260°C). These fumes can be harmful if inhaled, causing a condition known as polymer fume fever or Teflon flu.
Key points:
- Cooking at high temperatures or leaving an empty non-stick pan on a hot stove can cause the release of toxic fumes.
- Polymer fume fever can cause flu-like symptoms such as fever, chills, headache, and difficulty breathing.
- The effects of inhaling these fumes can be more severe in birds, leading to a condition known as “Teflon toxicosis.”
2. Use of certain chemicals during manufacturing
The production of non-stick surfaces involves the use of chemicals that have raised concerns among health experts. Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are two common chemicals used in the manufacturing process. Although many manufacturers have phased out the use of PFOA in recent years, PFOS is still used by some.
Key points:
- PFOA and PFOS are part of a broader group of chemicals known as per- and polyfluoroalkyl substances (PFAS).
- These chemicals have been linked to various health concerns, including kidney and testicular cancer, thyroid disease, immune system disorders, and developmental issues.
- While the amount of PFAS that may transfer from non-stick cookware to food is generally considered minimal, prolonged exposure or ingestion could potentially lead to health problems.
