What Pans Contain PFOA?

Published in Cookware Chemicals 3 mins read

Historically, Teflon pans are a very common type of cookware that has been known to use PFOA (perfluorooctanoic acid) in their manufacturing process. Teflon is the brand name for a synthetic chemical known as polytetrafluoroethylene (PTFE), which forms the non-stick coating. While modern non-stick cookware has largely transitioned away from PFOA, older Teflon products or those manufactured before the industry phase-out of PFOA would have contained residues of this chemical.

Understanding PFOA and Its Connection to Cookware

PFOA is a synthetic chemical that was widely used as a processing aid in the production of fluoropolymers, including PTFE, which is the basis for many non-stick coatings. Its historical use in the manufacturing of non-stick pans like Teflon meant that trace amounts could be present in the final product or released during use, especially at high temperatures.

  • PFOA's Role: PFOA was not an ingredient in the non-stick coating itself but rather a surfactant used to emulsify PTFE during its polymerization.
  • Health Concerns: This chemical has been associated with various health risks, including potential links to certain cancers, thyroid issues, and other adverse health effects when consumed or accumulated in the body.
  • Industry Shift: Due to these concerns, major manufacturers voluntarily phased out the use of PFOA in non-stick cookware by 2013-2015. Therefore, products labeled "PFOA-free" are now the industry standard.

Identifying Pans That May Contain PFOA

While it's important to note that most new non-stick cookware is PFOA-free, older pans might still pose a concern.

  • Older Teflon Pans: Any non-stick pan purchased before 2015, particularly those branded as Teflon, might have been manufactured using PFOA.
  • Unlabeled or Unknown Brands: Cookware from less reputable or unknown manufacturers, especially if purchased internationally or second-hand, might not adhere to the same PFOA-free standards.

Modern Non-Stick Cookware Alternatives

Today, consumers have many safer options for non-stick cookware that do not use PFOA or other "forever chemicals" like PFOS (perfluorooctanesulfonic acid).

  • PFOA-Free Labels: Look for explicit "PFOA-free" labeling on cookware.
  • Ceramic Cookware: Often made with natural materials and a non-stick coating derived from sand (silicon dioxide).
  • Cast Iron: Naturally non-stick when seasoned properly and extremely durable.
  • Stainless Steel: While not inherently non-stick, it's a popular choice for its durability and non-reactive properties, often paired with proper cooking techniques to prevent sticking.
  • Hard-Anodized Aluminum: Offers a durable, non-stick surface without the use of PFOA.

To minimize potential exposure, if you have very old non-stick pans, especially those with visible scratches or flaking, it may be advisable to replace them with newer, PFOA-free alternatives.
