"Pastured" is more commonly used to refer to poultry and their eggs, but pastured pork is out there, too. Pastured pork comes from pigs that live, more or less, how pigs might live if left to their own devices: in fields and woods, free to move around, with small shelters where they can sleep and give birth and feed their piglets.
Pastured pigs receive feed alongside the food they root for themselves. This feed may or may not be certified organic. Since they aren't crowded together in unhealthy conditions, pastured pigs don't receive unnecessary antibiotics or hormones.
Importantly, "pastured" doesn't have a legal meaning or certification process. Pastured animals tend to be raised on small farms and the farmers often sell at farmers markets and other direct-to-consumer methods. It is usually easy to find out more about a specific farm that sells pastured meat since they are often rightfully proud of how they care for their animals.
