The nutritional information may appear on posters, brochures, leaflets, or stickers near the potato display. Growing and Marketing Potatoes Potatoes are produced in nearly every State, but about half of the commercial crop is grown in Idaho, Maine, California, and Washington. Most of our year-round supply of fresh potatoes is harvested in September or October. These fall crops can be stored up to 9 months before shipment to retail outlets. Potatoes are usually brushed or washed at the packinghouse.
Dirty potatoes are unattractive, and the dirt itself adds to the weight of the consumer's purchase.
After cleaning, potatoes are mechanically sized and sorted into grades by packinghouse workers. Then, the potatoes are packed according to grade and size. The grade is often certified during packing by Federal-State inspectors. Packing is largely mechanized. Bags are generally weighed after packing to ensure that they are slightly overweight, thus allowing for normal shrinkage in storage and marketing.
