Final answer:
The Federal Food, Drug, and Cosmetic Act (FD&C Act) of 1938 expanded the definition of misbranding and adulteration, building upon the Pure Food and Drug Act of 1906. It gave the FDA more comprehensive regulatory powers over food, drugs, and cosmetics, including safety and labeling standards.
Step-by-step explanation:
The federal statute that expanded the definition of misbranding and adulteration is the Federal Food, Drug, and Cosmetic Act (FD&C Act) of 1938. This Act was a significant extension of the Pure Food and Drug Act of 1906, which initially established federal standards for food and drug purity. The FD&C Act broadened these standards to include more comprehensive regulations on the labeling and safety of foods, drugs, and cosmetics. It set the groundwork for the U.S. Food and Drug Administration to oversee the quality of substances sold as food and to monitor claims made on product labeling.
The FD&C Act is a critical piece of legislation that gives the FDA the authority to regulate the safety and efficacy of food, drugs, and cosmetics. It also marked a substantial shift in consumer protection by requiring that products be safe for use and accurately labeled. Additional amendments and acts, such as the Food and Drug Administration Amendments Act (FDAAA) of 2007, have continued to build on this foundation to enhance the regulatory framework.
