Enhanced Pork

A dish I've enjoyed at two Flushing Sichuan restaruants, Spicy & Tasty and Little Pepper, is called "enhanced pork." It's generally made with belly pork, and I think the word "enhanced" may refer to a curing process. But now with all this talk about "enhanced interrogation techniques" I'm getting worried. Could I have unwittingly eaten the meat of waterboarded or sleep-deprived pigs?
