DE Designation

Why does the OU not use a “DE” symbol?

Some kashrus agencies use a DE symbol to denote products that are made on “Dairy Equipment” but do not contain any actual dairy ingredients. The OU has chosen not to use a DE designation to minimize the possibilities of confusion for the kosher consumer. Also, to be a true DE product, the equipment must be properly cleaned of residue after a dairy production, and that level of cleanliness is sometimes difficult to maintain and guarantee.
