Panasonic Electric Rice Cooker
Lower concern; stainless steel cooking surface typical, but Panasonic offers no public PFAS disclosure.
Panasonic electric rice cookers typically use stainless steel inner pots and aluminum/stainless steel exteriors, materials inherently lower-risk for PFAS. The brand does not publicly disclose PFAS testing or make PFAS-free claims. No third-party lab data or recalls found in public records.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
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
Panasonic rice cookers use a stainless steel inner pot, which is chemically inert and does not leach metals into food under normal cooking conditions. The outer housing is typically aluminum or steel with plastic components (handles, lids). Stainless steel is the safest common cookware material for repeated boiling and steaming, as it lacks the ceramic glazes or nonstick coatings that can degrade or release harmful substances.
The brand's record and disclosure
Panasonic has no public history of major safety recalls specific to rice cooker leaching or chemical hazards. The company does not publish detailed PFAS disclosure statements for kitchen appliances, which limits transparency but does not indicate a problem. Panasonic maintains general ISO and IEC certifications for electrical safety and materials compliance in most markets.
How it compares in its category
Stainless steel inner pots are now standard in mid-to-premium rice cookers and represent the safest option; cheaper models may use bare aluminum or non-stick coatings. Panasonic's use of stainless steel puts it at the safer end of the category. Most electric rice cookers pose minimal chemical hazard if the inner pot remains intact, as cooking is enclosed and temperatures stay below 212°F during operation.
If you buy it
Inspect the stainless steel pot before use for cracks or discoloration; report any pitting or rust to the manufacturer as it may indicate poor quality. Do not exceed maximum water level markings, as overflow can damage electrical components. Replace the cooker if the inner pot becomes damaged, dented, or corroded, as this can enable leaching. Clean and dry the pot thoroughly after each use to prevent mineral buildup and corrosion.
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.”
Aluminum leaching from housing or lid contact
Outer aluminum housing and some internal aluminum components contact food indirectly via steam; exposure is minimal unless pot is damaged. Stainless steel inner pot itself does not leach aluminum.
Plastic component degradation (handles, lid seals, steam vents)
Plastic components exposed to prolonged heat and moisture may shed microparticles or off-gas over many years. Panasonic does not specify plastic type (BPA-free status) in public documentation for most models.
Bacterial or mold growth in steam vents and seal gaskets
If not cleaned regularly, moisture-trapping areas can harbor microorganisms. This is a maintenance issue, not a manufacturing defect, and applies to all rice cookers.
Stainless steel pot degradation over time
Corrosion or pitting of the stainless steel inner pot can occur if exposed to high-chloride environments (salt water, very hard water) or if scratched and left wet. This is not specific to Panasonic but depends on water quality and care.
Electrical safety and thermal burn risk
No recalls for electrical failure or burn hazard specific to Panasonic rice cookers; heating element design is standard and UL/IEC certified. Risk is behavioral (steam burns) rather than product defect.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
