Joseph Joseph 3-piece Cutting Mat Set
Lower concern. Cutting mats are bare food-contact plastics without intentional coatings.
Joseph Joseph cutting mats are TPE or polypropylene with no reported PFAS treatments. No brand disclosure on PFAS, but material type and end-use suggest lower risk than nonstick cookware.

The full breakdown
What it's made of and why it matters
Joseph Joseph cutting mats are typically made from TPE (thermoplastic elastomer) or polypropylene (PP), both non-porous plastics designed to resist staining and bacterial retention. These materials are chosen specifically because they do not leach into food under normal cutting use, they remain solid, unlike rigid plastics that can chip or degrade. Neither material requires a protective coating (like Teflon-type coating or ceramic), which eliminates coating-degradation and fume-release pathways common in cookware. The lack of metal additives or glazes also eliminates lead, cadmium, and aluminum leaching concerns tied to traditional cutting boards.
The brand's record and disclosure
Joseph Joseph is a UK-based kitchenware brand with no documented major product recalls or safety controversies on record for cutting mats. The company does not publicly disclose specific PFAS testing or avoidance commitments for this product line, placing it in the 'silent' category regarding emerging chemical concerns. No third-party certifications (e.g., Cradle to Cradle, BPA-free labeling) have been reported for these mats. The brand's overall safety profile is unremarkable, neither notably robust nor problematic, suggesting standard manufacturing without unusual red flags.
How it compares in its category
Cutting mats made from TPE or PP are among the safest in the cutting-board category because they avoid all the hazards of ceramic (lead in glazes), wood (mold/bacterial growth if poorly sealed), and glass (breakage risk, though chemically inert). Compared to bamboo or composite boards, plastic mats sidestep formaldehyde-based adhesives and dye contamination. They sit at the lower end of chemical-hazard risk, though they remain plastic and therefore vulnerable to long-term environmental concerns (PFAS, microplastics) not yet fully regulated for food-contact items.
If you buy it
Hand-wash these mats with warm soapy water and dry immediately; do not put them in the dishwasher, as high heat and detergent can degrade TPE surface texture over time. Avoid chopping very hot foods directly on the mat (steam can potentially cause minor surface softening); let foods cool first. Replace the mat if you notice permanent staining, discoloration, or visible surface damage, as compromised material may release particles during cutting. Store mats in a cool, dry place away from direct sunlight to extend lifespan (typically 3-5 years with normal use).
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.”
Microplastic shedding from surface wear
Cutting action on TPE/PP mats can generate microscopic plastic particles, especially after years of use; ingestion risk is low for infrequent household users but increases with repeated chopping of abrasive vegetables or high-frequency commercial use.
Lead or cadmium in colorants/dyes
Joseph Joseph cutting mats are solid-color plastics with no reported contamination; modern PP/TPE manufacturers avoid heavy-metal pigments, but no independent testing on this specific product line is publicly available to confirm.
BPA or other bisphenols from plastic resin
BPA was phased out of food-contact plastics in most Western markets by the 2010s; TPE and polypropylene formulations do not inherently require BPA, but Joseph Joseph does not provide explicit BPA-free certification for these mats.
Surface degradation and leaching under heat stress
While TPE and PP are stable at room temperature, exposure to sustained high heat (above 60-70°C / 140-160°F) or boiling liquids can soften or slightly degrade the surface, potentially releasing trace plastic compounds; not a typical cutting-mat use case, but relevant if mats are placed under hot pans or in very hot kitchens.
Bacterial or mold retention in seams or cracks
If the 3-piece set design includes interlocking seams or edges, bacteria can trap in crevices if mats are not fully dried after washing; regular, thorough drying and inspection for cracks minimizes this low-risk pathway.
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.
