Consumers expect a food described as "pure" or "100% pure" to be uncontaminated and unadulterated, and to contain only substances or ingredients that are listed on the label. Claims to the effect that a food does not contain an ingredient or substance must be factual and not misleading.

• Current Good Manufacturing Practice for Finished Pharmaceuticals: The US FDA provides regulations for the manufacturing of finished pharmaceuticals. These regulations include requirements for equipment construction to ensure that surfaces that contact components, in-process materials, or drug products shall not be reactive, additive, or absorptive so as to alter the safety, identity, strength, quality, or purity of the drug product beyond the official or other established requirements.
