In the "Cheeseburger & Fries" episode of History Channel's Food Tech, host Bobby Bognar tours factories and farms around the country involved in making cheeseburgers and fries: a cattle feedlot in Illinois, a bun factory in California, a cheese factory in Wisconsin, a pickle factory in North Carolina, a lettuce farm in California, an onion seed producer in Idaho, a potato farm in Washington, and a tomato farm in California.
This episode aired in January 2010, but since I only came across it now I figured other people may have missed it too. Watch the full 45-minute episode at history.com.
