Now, none of the samples were found to be unsafe for human consumption in any way, and it's likely that many would have no objection to eating pig or, even, horsemeat. (Horse is a traditional meat in some areas of France, among other places.) The pork can be explained away by the fact that both pork and beef are processed at the same plant, though nobody seems to have any idea how a significant amount of horsemeat made its way into the ground beef. But there are two major concerns here. The first is for people with dietary restrictions: neither pig nor horse is kosher, and pig is not halal.
