Treated Wood for Interior Use

Q: Is it okay to use treated wood inside?

A: Many pressure-treated wood products do not emit any vapors and are safe for interior use, but you should check the information of specific products. Treated wood is commonly used for the sill plates of homes and for fire-retardant materials. Treated wood should not, how-ever, be used for countertops or where it may become a component of food. In fact, the Food and Drug Administration does not recommend using any wood for kitchen countertops or food-cutting boards because knife cuts may allow food particles to become entrapped, creating an unsanitary environment.
