Stone Mountain Pecan has based its reputation on bringing quality pecan products to market and, in so doing, taking measured steps to ensure product purity before shipment. The company processes the inshell pecans and sells the nut meats. Before the pecans are placed into boxes, personnel visually inspects them for signs of metal contaminants. They also use a series of magnets to remove any ferrous metals. Once the inspection is complete, the Pecans are placed into 30 pound boxes, ready for shipment. Although Stone Mountain has never had a problem detecting metal visually, they wanted to add another margin of safety.
