Foreign material is any material that is not the potato tuber itself. It is “trash” or “garbage” in potatoes. Many foreign materials originate in the field, but others enter the product stream through equipment and during storage and handling. Whether potatoes are destined for the fresh market or processing, foreign material is a great concern to the Idaho potato industry. By minimizing foreign material in the field, in storage, and in the processing plant, growers and processors help maintain a high-quality product, safe standards, and consumer confidence. The video “Continuing to Manage Foreign Material for Quality Idaho Potatoes” outlines ways you can reduce unwanted or foreign material in your potatoes. English version
