Final answer:
During President Roosevelt's second term, food and meat regulation was significantly reinforced with the passage of the Meat Inspection Act of 1906 and the Pure Food and Drug Act of 1906, following the public reaction to Upton Sinclair's 'The Jungle'.
Step-by-step explanation:
The regulation of food and meat products during President Theodore Roosevelt's second term in office was significantly impacted by legislation prompted by Upton Sinclair's exposé on the meatpacking industry, The Jungle. Following public outcry and a presidential commission that corroborated the harrowing conditions described in Sinclair's work, Roosevelt advocated for the passage of the Meat Inspection Act of 1906 to establish government inspection and sanitation standards in the meat industry.
Alongside the Meat Inspection Act, the Pure Food and Drug Act of 1906 also passed, creating the Food and Drug Administration (FDA) and requiring clear labeling of food and drug products, including their ingredients and prohibiting adulterated products.
