Lodge Cast Iron Classic Cast Iron Skillets
Lower PFAS concern, bare cast iron has no synthetic coatings.
Lodge cast iron skillets are made from bare cast iron seasoned with natural oils, with no Teflon-family coating or synthetic nonstick coatings. The material itself is inherently PFAS-free. Lodge does not market PFAS-free status because the product category presents no typical PFAS exposure pathway.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
Lodge Classic skillets are solid cast iron with no enamel, nonstick coating, or ceramic finish. The iron is seasoned at the factory with a thin layer of vegetable oil that polymerizes when heated, creating a natural patina rather than a chemical barrier. This design eliminates the primary chemical hazards found in coated cookware (Teflon-type coating, lead-glazed surfaces, synthetic polymers) because there are no synthetic coatings to degrade or off-gas.
The brand's record and disclosure
Lodge Manufacturing has operated in the United States since 1896 and maintains manufacturing in Tennessee. The company does not publish detailed material certifications or third-party testing results on its website, and makes no explicit PFAS or heavy-metal safety claims. No major product recalls or safety violations specific to chemical contamination have been publicly documented for Lodge cookware in recent decades. The brand's silence on testing may reflect the simplicity of their product (bare cast iron requires little regulatory scrutiny) rather than a transparency problem.
How it compares in its category
Bare cast iron is one of the safest cookware choices from a chemical leaching perspective because it has no surface coatings to wear, peel, or release particles. Enameled cast iron (Lodge does make this line) introduces glazes that may contain lead or cadmium, and nonstick alternatives carry Teflon-type coating degradation risk. Bare cast iron is essentially unchanged in formulation and risk profile for over a century, making it a lower-chemical alternative to modern nonstick and ceramic cookware.
If you buy it
Use Lodge skillets on medium to medium-high heat; cast iron retains and distributes heat efficiently, so high flame is unnecessary and risks damaging the seasoning layer. Hand wash only and dry immediately to prevent rust. Avoid acidic foods (tomato, vinegar, citrus) for extended cooking, as acid can strip seasoning and increase iron leaching into food. Reseason periodically by wiping with a thin layer of neutral oil and heating on the stovetop or in the oven at 350-400F for 5-10 minutes to maintain the protective patina.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Iron leaching into food
Bare cast iron can release small amounts of iron into acidic or prolonged-cooked foods, especially if seasoning is thin or damaged. For most people this is nutritionally neutral or beneficial; those with hemochromatosis should avoid cooking acidic meals in unseasoned or worn cast iron.
Rust formation and corrosion
If not dried and maintained properly, cast iron rusts and can flake rust particles into food. Rust itself is not acutely toxic but is aesthetically and hygienically undesirable. Proper care eliminates this risk entirely.
Thermal shock and cracking
Dropping a hot cast iron skillet into cold water or exposing it to sudden temperature changes can cause cracking or warping. This is a functional failure, not a chemical hazard, but damaged cookware should be retired.
Manufacturing residues or mill scale
Lodge products are cleaned and seasoned at the factory; no recalls or documented cases of manufacturing debris, mill scale, or heavy metal contamination in Lodge skillets have been publicly reported.
Lead or cadmium in cast iron itself
Modern cast iron cookware (including Lodge) is not formulated with lead or cadmium additives. The iron ore source and smelting process are not disclosed by Lodge, but no credible testing or recalls have identified these metals in their products.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 95% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
