Stainless steel: the gold standard for safe cooking
Food-service grade 18/10 stainless steel (containing 18 percent chromium and 10 percent nickel) is the material standard in professional kitchens and hospitals globally. The chromium creates a passive oxide layer that makes the surface highly resistant to corrosion and material transfer.

Stainless steel: the gold standard for safe cooking
Food-service grade 18/10 stainless steel (containing 18 percent chromium and 10 percent nickel) is the material standard in professional kitchens and hospitals globally. The chromium creates a passive oxide layer that makes the surface highly resistant to corrosion and material transfer.
Cast iron and enameled cast iron: traditional safety
Seasoned cast iron is one of the oldest cooking surfaces in use. Its safety profile is well established. Iron transfer to food does occur, particularly with acidic foods -- but for most people, dietary iron is a nutrient, not a contaminant.
What to look for
18/10 stainless steel grade
This is the most corrosion-resistant and stable stainless alloy for cookware. Lower grades (like 18/0) are less stable.
PFOA-free certification
All modern nonstick pans should be PFOA-free. This has been standard since 2013 following regulatory action. If a pan doesn't mention this, ask the manufacturer.
No damaged coatings
Scratched or flaking nonstick coatings should be replaced. While swallowing small fragments of PTFE is not believed to be harmful, cooking on damaged coating surfaces can create off-flavors and is not recommended.
Avoid uncoated aluminum for acidic foods
Uncoated aluminum can react with acidic ingredients (tomatoes, citrus, wine-based sauces) and transfer a metallic flavor. Hard-anodized aluminum is stable and does not have this issue.
Lead and cadmium-free enamel
When buying enameled cast iron, verify that the enamel is certified free of lead and cadmium -- some imported pieces have tested positive for these in independent testing.
FAQs
Yes. Modern PTFE nonstick cookware manufactured after 2013 is PFOA-free. It is safe at temperatures below 500F, which covers all normal cooking. The concern was PFOA, not PTFE itself.
Yes. 18/10 stainless steel (18% chromium, 10% nickel) is highly stable and leaches negligible amounts of metal under normal cooking conditions. It is the standard for food service worldwide.
Yes, especially with acidic foods cooked in unseasoned cast iron. For iron-deficient individuals, this can be beneficial. The amount is generally small but measurable.
Avoid old nonstick pans from before 2013 that may contain PFOA. Also avoid uncoated aluminum with acidic foods, and scratched nonstick of any generation.
