Upton Sinclair's The Jungle, excerpt

This excerpt is from Upton Sinclair's novel, The Jungle, which recounted in a realistic style the fictional story of immigrant workers in the Chicago meatpacking plants. Sinclair had investigated the meatpacking plants, and the descriptions in his novel were based firmly on his observations. Sinclair was most concerned for the safety and rights of the workers in these plants, but the American public and President Theodore Roosevelt were perhaps even more appalled by the danger that the unregulated and unsanitary meatpacking plants posed to American consumers. With gigantic plants processing meat for entire regions of the country, the sanitary conditions of the industry could no longer remain an issue of local importance. Roosevelt urged Congress to address the issue, and in $1906$ the first national inspection system was established by law. Sinclair and other critics of the meatpacking industry welcomed governmental regulation, but were deeply disappointed by the weak provisions and insufficient funding provided for the new regulatory system.
