Although Congress began investigating drug purity in the 1840s, it was during the Progressive Era that it approved the first federal regulations protecting consumers’ health and safety. When Upton Sinclair’s 1906 novel The Jungle revealed food adulteration and unsanitary practices in meat production, public outrage prompted Congress to establish federal responsibility for public health and welfare. The Pure Food and Drug Act of 1906 prohibited the sale of misbranded or adulterated food and drugs in interstate commerce and laid a foundation for the nation’s first consumer protection agency, the Food and Drug Administration (FDA).
