Cast Iron Cookware — food safety profile
Low riskCast iron skillets, Dutch ovens, and griddles.
What is this product?
Cast iron skillets, Dutch ovens, and griddles. Iron leaches from cooking surface into food, especially acidic foods (tomato sauce, citrus). This is a benefit-risk duality: iron leaching is therapeutic for iron-deficient populations but potentially harmful for those with hemochromatosis or iron overload. Seasoning (polymerized oil coating) reduces but does not eliminate leaching.
