We get alot of chemicals in in them at the brickyard... that being said, the food service is a great place to start... A guy I work with got 14 of them from a local company that makes pizza crust, he bought it (14 filled with dough and icecream cones for bear hunting. ) That being said, another aquaintance found 3-4 cheap at a local pickle caning factory... brine cant be that bad....
