Pig (domestic)

The domestic pig or swine is a mammal native to Eurasia, now an important food animal in nearly every part of the world. Pigs were first domesticated in prehistoric times. They were brought to the Americas by European settlers, and to Oceania by the Polynesians.

Nearly every part of pigs is eaten: the flesh produces pork and bacon, ribs become spareribs, and even the feet are eaten. Pork is especially important to Chinese and Polynesian cuisine. On the other hand, Judaism and Islam ban the eating of pigs or any other use of them, probably because of ancient encounters with trichinosis.

In addition to trichinosis, pigs are a major transmitter of influenza viruses to humans.
