ABSTRACT
At the end of World War II the fields of Europe were full of shrapnel and pieces of metal ranging in size from minuscule to immense. In order to remove these metal contaminants from harvested crops, such as potatoes, carrots, and beets, huge magnets were erected above conveyor belts. As time went by, an obvious need for other food products to be “metal detected” was identified and more sophisticated technology was developed, eventually evolving into the very specialized metal detection systems available today.
