T-fal non-stick coatings are made from PTFE, used in many other non-stick cookware brands. PTFE is non-toxic and stable under average cooking temperatures. However, concerns arise when PTFE-coated cookware is overheated. At temperatures above 500°F (260°C), PTFE can break down and release toxic fumes that may cause flu-like symptoms, commonly known as “Teflon flu” or “polymer fume fever.” This is a temporary but unpleasant condition. Overheating can also cause the non-stick coating to deteriorate, which may release small particles into your food. To ensure the safe use of T-fal cookware, follow these guidelines: -Never preheat an empty pan. -Avoid using metal utensils. -Cook at low to medium heat settings. -Properly maintain and clean your cookware to prolong its life and ensure safety.
