It is typically hydrogenated (which produces trans fats as a byproduct), and often treated with bleaching and deodorizing agents, emulsifiers, and antioxidants, such as BHT. Such treatment makes lard shelf stable. (Untreated lard must be refrigerated or frozen to prevent rancidity.)
It may be stable but that doesn't make it healthy.
