Final answer:
In 1906, Upton Sinclair's novel 'The Jungle' exposed the unsanitary practices of the beef packing industry, leading to the passage of the Federal Meat Inspection Act and the Pure Food and Drug Act.
Step-by-step explanation:
In 1906, Upton Sinclair published The Jungle, a muckraking novel that exposed the unsanitary practices of the beef packing industry.
The book's horrific descriptions of violations of basic sanitation shocked readers and led to public support for greater regulation of the meatpacking industry.
As a result, the government passed the Federal Meat Inspection Act and the Pure Food and Drug Act in 1906, which established guidelines for sanitation, required federal meat inspectors, and regulated the use of narcotics in medicines.
