Ingesting small flakes of Teflon from cookware is generally considered safe. Teflon is a brand name for a type of nonstick coating called polytetrafluoroethylene (PTFE). When used within the recommended temperature limits, PTFE is stable and does not release toxic fumes or substances. Ingesting small flakes of Teflon, even if accidentally consumed, is not known to cause harm.
However, it's important to note that if Teflon-coated cookware is heated to very high temperatures (above 500°F or 260°C), it can release fumes that may cause a condition called polymer fume fever. This condition typically results in flu-like symptoms such as fever, headache, and respiratory irritation. It's advisable to use Teflon-coated cookware within the manufacturer's recommended temperature guidelines and avoid overheating it.
Additionally, if the Teflon coating on your cookware is visibly scratched or damaged, it's recommended to replace the cookware. This is because damaged coatings may release small particles that could mix with food, and while they are generally considered inert and non-toxic, it's best to avoid consuming them.
To minimize the risk of ingesting flakes from Teflon cookware, it's good practice to use wooden or silicone utensils that won't scratch the coating, and to avoid using metal utensils or abrasive cleaning materials that could damage the nonstick surface.
If you have concerns about the safety of your cookware or potential health risks, it's always best to consult the manufacturer's guidelines or contact the manufacturer directly for specific information and recommendations.
