Throw Out Your Scratched Nonstick Cookware
Cooking with scratched nonstick cookware may pose health risks due to the potential release of harmful substances from the damaged coating into your food. Nonstick cookware is typically coated with polytetrafluoroethylene (PTFE), commonly known as Teflon. When the nonstick surface is scratched or damaged, the integrity of this coating is compromised, and the release of PTFE into your food becomes more likely, especially when exposed to high temperatures during cooking. Overheating scratched nonstick pans can lead to the emission of toxic fumes, including perfluorooctanoic acid (PFOA), which has been linked to adverse health effects, including respiratory issues known as “polymer fume fever.”
In addition to the potential release of harmful chemicals, the ingestion of PTFE particles from scratched nonstick cookware can raise health concerns. While PTFE itself is generally considered inert and not harmful, the ingestion of its particles may lead to flu-like symptoms known as “Teflon flu.” Moreover, the long-term effects of continuous exposure to PTFE particles are not yet fully understood. To maintain both the effectiveness of your nonstick cookware and your health, it is advisable to replace scratched or damaged pans and use utensils that are gentle on the nonstick coating to avoid compromising its integrity during cooking.
