Food Safety Standards Compliance
EuroStone Quartz surfaces are certified to NSF/ANSI Standard 51 by NSF International, an independent third-party organization that tests and certifies products for food safety. This certification validates that our engineered quartz surfaces are safe for direct food contact in both commercial and residential kitchen applications.
NSF/ANSI 51 certification requires rigorous testing to ensure materials do not harbor bacteria, resist common cleaning chemicals, and will not leach harmful substances into food. Our non-porous quartz surfaces exceed these stringent requirements, providing peace of mind for food service professionals, healthcare facilities, and homeowners.
This independent certification demonstrates EuroStone's commitment to product safety and quality. The NSF mark on our products signifies compliance with North American health and safety standards recognized by regulatory agencies, building departments, and architectural specifications worldwide.
Understanding NSF/ANSI 51
What It Means
NSF/ANSI Standard 51 is the American National Standard for food equipment materials. Products certified to this standard have been tested and proven safe for surfaces that come into direct contact with food, including countertops, cutting boards, and food preparation areas.
Testing Requirements
Materials must pass comprehensive testing for chemical safety, cleanability, bacteria resistance, and durability under repeated cleaning cycles. Testing simulates real-world commercial kitchen conditions to ensure long-term performance and safety.
Who Requires It
NSF/ANSI 51 certification is often required by health departments for commercial kitchens, restaurants, hospitals, schools, and food processing facilities. Many architects and designers also specify NSF-certified materials for residential projects.
Independent Verification
NSF International is accredited by ANSI (American National Standards Institute) and recognized globally. Their certification provides independent, third-party validation that products meet strict public health and safety standards.

Maintaining Food Safety Standards
Daily Cleaning
Clean surfaces with warm water and mild dish soap or pH-neutral cleaner. For commercial applications, use approved sanitizing solutions following manufacturer dilution ratios.
Periodic Sanitization
For food service environments, sanitize high-touch areas multiple times daily. NSF-certified surfaces maintain antibacterial properties through repeated cleaning without degradation.
What to Avoid
While NSF-certified quartz is highly chemical resistant, avoid abrasive cleaners, steel wool, or highly concentrated chemicals that may dull the polished finish over time.
Specify with Confidence
NSF/ANSI 51 certification provides the assurance you need for commercial and residential food service applications.
