Bad Cow Disease

"Mary had a little lamb / And when she saw it sicken / She shipped it off to Packingtown / And now it's labeled chicken."

That little ditty famously summarized the message of "The Jungle," Upton Sinclair's 1906 exposé of conditions in America's meat-packing industry. Sinclair's muckraking helped Theodore Roosevelt pass the Pure Food and Drug Act and the Meat Inspection Act - and for most of the next century, Americans trusted government inspectors to keep their food safe.
