 The Act prohibited, under penalty of seizure of goods, the interstate transport of food that had been "adulterated".The act applied similar penalties to the interstate marketing of "adulterated" drugs, in which the "standard of strength, quality, or purity" of the active ingredient was not either stated clearly on the label or listed in the "United States Pharmacopeia" or the "National Formulary".The responsibility for examining food and drugs for such "adulteration" or "misbranding" was given to Wiley's USDA Bureau of Chemistry.
