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.

In addition to Smithfield, the company's brands include Armour, Eckrich, Gwaltney, Kretschmar, and others. The company's roots stretch back to 1936, when the Luter family opened a packing plant in Virginia.

Terms of the purchase value Smithfield's stock at $34 a share — a premium of more than 30 percent over the company's closing share price yesterday. The Wall Street Journal, which first reported the sale, says the company's shares rose sharply before the markets opened Wednesday.

The deal will require approval from U.S. regulators before it is final.

"This is a great transaction for all Smithfield stakeholders, as well as for American farmers and U.S. agriculture," Smithfield president and CEO Larry Pope said. "We have established Smithfield as the world's leading and most trusted vertically integrated pork processor and hog producer, and are excited that Shuanghui recognizes our best-in-class operations, our outstanding food safety practices and our 46,000 hard-working and dedicated employees."
