Description: The level of mechanical injury of potatoes was measured in a survey of table potato packing companies. Four packing lines were monitored during a two year study with samples taken at eight loca tions on each line. The sampling procedure was repeated three times during the first season and once during the second year. A damage index that included black spot and measures the severity of injury sustained by the potatoes was calculated for each sample. The potatoes at the on-farm storages had an average damage index of 490.6 whereas the indexes of the graded potatoes packed as count boxes, Canada No. 1 and Canada No. 2, were 529.4, 594.1, and 591.7, respectively. Parameters considered to influence the damage levels during the han dling and grading process were compared with the injury levels of the potatoes at each sampling location. The parameters found in the anal ysis to have a direct relationship to damage levels were the accumulated drop heights and the number of drops occurring on the packing lines.
