Reconstruction
On June 30, 1906, President Theodore Roosevelt approved the federal Food and Drugs Act, commonly called the Pure Food and Drugs Act or Wiley Act. The statute made it unlawful to introduce adulterated or misbranded foods, drugs, medicines, and liquors into interstate or foreign commerce. Offending goods could be seized, while responsible businesses or individuals faced prosecution. Enforcement went to the Department of Agriculture's Bureau of Chemistry, the scientific and administrative predecessor of the Food and Drug Administration.
Congress was responding to problems created or magnified by an expanding industrial marketplace. Foods increasingly traveled through national networks of factories, wholesalers, railroads, and urban retailers. Consumers could not readily inspect distant production or detect substitutions, decomposition, chemical preservatives, or misleading labels. Chief chemist Harvey Washington Wiley had investigated adulteration and organized highly publicized human feeding experiments, known as the Poison Squad studies, involving preservatives. Women's organizations, journalists, physicians, state officials, agricultural chemists, and sections of the food industry also campaigned for national rules. Upton Sinclair's 1906 novel The Jungle helped produce the final political opening, but the legislation followed decades of agitation and repeated failed bills rather than a single exposé.
For food, the act prohibited practices such as removing valuable constituents, substituting cheaper material, concealing damage or inferiority, adding substances that made a product harmful, and marketing filthy or decomposed goods. False or misleading labeling was also prohibited. It did not, however, establish modern premarket approval, comprehensive ingredient disclosure, nutritional labeling, or a general system of mandatory federal food standards. Meat inspection was addressed separately by the Meat Inspection Act, approved on the same day.
Administration required more than written law. Bureau chemists and inspectors collected commercial samples, developed analytical methods, and presented evidence in seizure proceedings and criminal cases. Early disputes concerned sodium benzoate, saccharin, caffeine, chemically bleached flour, and other innovations whose safety or legal status was contested. Laboratory methods, including microscopic examination for mold in ketchup, became practical tools for translating statutory language into enforceable judgments.
The act was foundational but limited. Courts narrowed some applications, and regulators generally had to act after unlawful products entered commerce. The 1938 Federal Food, Drug, and Cosmetic Act replaced it with substantially broader authority after further public-health disasters exposed its weaknesses. Nevertheless, the 1906 measure established a durable principle of the modern food system: products moving through national markets could be subjected to federal scientific inspection and truthful-labeling requirements. Today's rules for food identity, additives, manufacturing controls, and labeling developed later, but they belong to the regulatory tradition this act helped institutionalize.
Historical context
The United States was becoming a national mass market linked by railroads, industrial processing, advertising, and rapidly growing cities. The 1900 census counted about 76.2 million residents, rising to 92.2 million by 1910; roughly two-fifths were classified as urban under the period's census definition. Washington, D.C., grew from 278,718 residents in 1900 to 331,069 in 1910. Federal regulation was expanding during the Progressive Era as scientific laboratories, investigative journalism, organized consumer campaigns, and national commerce challenged older systems of local inspection.

Historical interpretation
ModerateThe roles of industrialization, scientists, consumer organizations, journalists, reform politicians, and supportive businesses are well documented, but historians differ over their relative importance. Attributing passage primarily to The Jungle would oversimplify a decades-long coalition and legislative struggle.
