Smithfield Foods, Inc., is a pork producer and food-processing company based in Smithfield, Virginia, in the United States, and a wholly owned subsidiary of WH Group of China. Founded in 1936 as the Smithfield Packing Company by Joseph W. Luter and his son, the company is the largest pig and pork producer in the world.
In addition to owning over 500 farms in the US, Smithfield contracts with another 2,000 independent farms around the country to grow Smithfield's pigs. Outside the US, the company has facilities in Mexico, Poland, Romania, Germany, and the United Kingdom.
Globally the company employed 50,200 in 2016 and reported an annual revenue of $14 billion. Its 973,000-square-foot meat-processing plant in Tar Heel, North Carolina, was said in 2000 to be the world's largest, processing 32,000 pigs a day.
As of 2006 Smithfield raised 15 million pigs a year and processed 27 million, producing over six billion pounds of pork and, in 2012, 4.7 billion gallons of manure. Killing 114,300 pigs a day, it was the top pig-slaughter operation in the United States in 2007; along with three other companies, it also slaughtered 56 percent of the cattle processed there until it sold its beef group in 2008. The company has sold its products under several brand names, including Cook's, Eckrich, Gwaltney, John Morrell, Krakus, and Smithfield.
