The USDA’s National Organic Standards, federal regulations that govern how organic food is grown and processed, require that Whole Foods Market stores have physical barriers to prevent commingling of organic and non-organic products.

The USDA-accredited agency that certifies Whole Foods Market stores also requires that explanatory signs are posted where equipment, such as bread slicers or coffee grinders, could be used by customers to process both organic and non-organic products. Additionally, store team members must prevent contact of organic production and handling operations with prohibited substances.
