Is non stick coating in rice cooker harmful?

Non-stick coatings in rice cookers, typically made from materials like Teflon, are generally considered safe when used according to manufacturer guidelines. However, overheating or scratching the coating can release harmful substances. It's important to use utensils that won't damage the surface and to avoid high temperatures. If you have concerns, consider using a rice cooker with stainless steel or ceramic interiors as alternatives.
