Teflon cookware
Several years ago, the US Environmental Protection Agency found a carcinogenic substance called PFOA inside Teflon cookware. Agency officials added that Teflon secretes toxic substances and gases at high temperatures, which can lead to various diseases and even cancer. However, it’s important to note that if you keep your Teflon cookware in good condition and undamaged, you can continue to use it, but at the same time, avoid long or high-temperature cooking.
