Name that company

I trace my roots back to the 1936 founding of a meatpacking company in Virginia. Today I’m a global food giant and the world’s biggest pork processor and hog producer, with revenue of $14 billion in 2015. I process more than 30 million hogs annually and have processing plants in the United States, Poland and Romania. My brands include Nathan’s Famous, Armour, Carando, Cook’s, Curly’s, Eckrich, Farmland, Gwaltney, Kretschmar, John Morrell, Healthy Ones, Margherita and more. I was acquired by a Chinese company for close to $5 billion in 2013. I employ about 50,000 people around the world. Who am I? Last week’s trivia answer: Nucor
