Pork is the culinary name for the meat of a domestic pig (Sus scrofa domesticus). It is the most commonly consumed meat worldwide, with evidence of pig husbandry dating back to 5000 BC. Pork is eaten both freshly cooked and preserved. Curing extends the shelf life of the pork products. Ham, smoked pork, gammon, bacon and sausage are examples of preserved pork. Charcuterie is the branch of cooking devoted to prepared meat products, many from pork.
