No, accidentally consuming parts from a non-stick coating of Mauviel1830 is not harmful to your health.
Possible release of the non-stick coating occurs in the form of powder or flakes. When this gets into the food, it feels like eating sand. If you have accidentally eaten powder or flakes of the non-stick coating, this leaves the body through the normal route.
That the non-stick coating starts peeling can happen after a knock or blow to the pan, destruction or accidentally dropping the pan. In addition, the spray head may not have adhered to the non-stick coating properly during the production process. Anyway, in case the non-stick coating starts peeling we are happy to check the pan for you. We kindly ask you to send us photos of the pan and the peeling non-stick coating and your proof of purchase via the contact sections.
