If it is raised on a large commercial farm the pigs never root in the ground and are never exposed to it, they are kept indoors . If it’s a pig from a small farm that is kept outdoors and roots around it could be contaminated z
But you aren’t likely to find meat from that latter pig in your supermarket.
Sorry, I don't understand this statement. Don't some supermarkets carry meats from small farms and such? Merry Christmas.
