Upton Sinclair didn't have to lie or go very deep undercover. All he had to do was carry a metal lunchbox and he blended right into the factory floor. But this wasn't any factory. This was a part of Chicago's main export, the slaughterhouse and meatpacking plants. And what he found there would shock him and all of American's when he published the results in his novel The Jungle. And the public outcry would be exactly what Teddy Roosevelt needed to help put two new regulations in check: The Pure Food & Drug Act and the Federal Meat Inspection Act.
