Mold & Bacteria Resistance

Solid Surface
Wilsonart® Solid Surface products - Gibraltar® and Earthstone® - meet FDA* standards for food contact, ASTM International standards (G-21 and G-22) for fungal and bacterial resistance and have NSF International approval in Class 51 for both "Splash Zone" and "Food Zone" areas. Of course, good hygiene is always recommended with the use of any product.

Granite
Granite has small surface crevices so it's harder to keep them free of mildew and bacteria. Proper sealing and maintenance can protect against these conditions - as long as the sealant remains intact. Even so, granite surfaces do not currently meet FDA and NSF standards for food preparation areas. Nor do they meet ASTM standards (G-21 and G-22) for fungal and bacterial resistance.
