Final answer:
The correct answer is A. the Pure Food and Drug Act, which was passed in 1906 and set federal standards of inspection and sanitation for meatpackers and required drug makers to list ingredients. This act also led to the creation of the FDA, which ensures the safety and efficacy of food, drugs, and cosmetics today.
Step-by-step explanation:
The act that requires all foods and drugs to meet a standard of strength and purity is A. the Pure Food and Drug Act. This law, passed in 1906, was crucial in setting federal standards of inspection for meatpackers and ensuring drug makers list their ingredients. The need for such regulation became evident due to muckraking exposés, which revealed significant issues with adulterated foods and patent medicines that were neither safe nor effective. It was a key legislative achievement of the Progressive Era and laid the foundation for subsequent food and drug safety laws.
In response to Upton Sinclair's report on the meatpacking industry, government legislation, including the Pure Food and Drug Act, began to protect consumer health and ensure the safety of food and medicine. This act resulted in the creation of the Food and Drug Administration (FDA), which today continues to regulate the safety, efficacy, and labeling of food, drugs, and cosmetics.
When it comes to modern regulation, most federal laws concerning the FDA are articulated within the Food, Drug, and Cosmetic Act, which is an expansion and amendment of the original 1906 law and continues to be enforced to maintain the purity and safety of consumer products.
