How did the book the jungle show that the meatpacking industry needed to be regulated?

Upton Sinclair's "The Jungle" exposed the horrific conditions in the meatpacking industry, highlighting unsanitary practices, worker exploitation, and the lack of safety measures. The graphic descriptions of contaminated meat and the mistreatment of laborers underscored the urgent need for regulation to protect both consumers and workers. Sinclair's work galvanized public outrage, leading to the establishment of food safety laws and the creation of the Pure Food and Drug Act and the Meat Inspection Act in 1906. Ultimately, the book demonstrated that unregulated industries could jeopardize public health and welfare.
