The makers of Smithfield Ham, an icon on America's culinary scene for decades, are selling the publicly traded company to China's Shuanghui International Holdings Limited for about $4.72 billion in cash. The deal also includes an exchange of debt.

The purchase values Smithfield Foods at $7.1 billion — a figure that would make the purchase "the largest Chinese takeover of a U.S. company," according to Bloomberg News.
