All I can say is eeew! (And who discovered this?!?!?!) http://www.unbelievable-facts.com/2013/03/6-scary-food-ingredients-we-have_14.html?m=1
I read over and over that our foods should be more like what our grandparents ate. Of course I remember my grand dad eating the salt pork in my grandmothers pork and beans! He only lived to be 88. Died from a cancer he got from Redtop chewing tobacco. My grandparents grew most of their food. Their dirt floor cellar was lined with shelves of canned food including meats. They didn't have a pressure canner and no one ever got sick from their food.
