Experts are advising that nonstick cookware should be replaced if it is chipped and peeling, as it may pose health risks. The condition of the cookware, including flaking and peeling of the nonstick coating, is a key factor in determining when to replace it. There is concern that damaged nonstick cookware, potentially containing Teflon, could be harmful to one's health, with some referring to the issue as "Teflon flu".
