Potatoes; Grade Standards

This rule revises the United States Standards for Grades of Potatoes. These standards are issued under the Agricultural Marketing Act of 1946. The rule provides en route or at destination tolerances for the U.S. No. 1 and U.S. No. 2 grades, revises current tolerances in all grades, deletes the U.S. Extra No. 1 grade and "Unclassified" section, and defines damage and serious damage by the following defects which will be added to Table III of the External Defects section: Cuts, Clipped Ends, Elephant Hide, Flattened or Depressed Areas/Pressure Bruises, Grub Damage, Nematode (Root Knot), Rodent or Bird Damage, Russeting, Silver Scurf, Sunken Discolored Areas, and Surface Cracks. The following defects and scoring guidelines that are currently listed in Table III of the External Defects section are also revised to reflect current inspection instructions: Air Cracks, Bruises, External Discoloration, Flea Beetle Injury, Greening, Growth Cracks, Rhizoctonia, Pitted Scab, Russet Scab, Surface Scab, and Wireworm or Grass Damage. Also, changes to the current scoring guide for sprouts are being made. In the Internal Defects section, Internal Black Spot is revised by implementing a color chip to assist in the scoring of this defect. Also, Table IV in this section is redesignated as Table I. Additionally, a revised large size is added as well as the inclusion of Chef and Creamer sizes. Most of the changes were the result of the detailed work performed by the Joint U.S./Canadian Potato Council that was charged with harmonizing the U.S. and Canadian Potato Grade Standards. This rule updates and revises the standards to more accurately reflect today's marketing practices.
