The Jungle by Upton Sinclair is, as usual, mentioned. This was a work of fiction, and most claims by Sinclair were either wildly exaggerated based on hearsay or fabricated entirely. Sinclair himself rejected the legislation regulating the meat-packers that followed, since the public would be paying for it, rather than them, and this allowed them to defray the costs. https://secure.wikimedia.org/wikipedia/en/wiki/The_Jungle#Public_and_federal_response
