How did muckrakers such as upton sinclair influence president roosevelt's policy? what new heath laws were passed? why were they passed?

Answer 1

Upton Sinclair's novel The Jungle drew attention to atrocious practices in the meat packing industry. His expose of unsanitary conditions and food that was dangerous to eat, and the public outcry arising from it, led President Roosevelt to have the food industry investigated. In June of 1906 he signed into law both the Meat Inspection Act and the Pure Food and Drug Act.
