Sprouting, decay, and mold may occur if onions are stored at high temperatures or high humidity.
Water-soaked spots indicate freeze damage. Store properly.
Green spots may develop if onions are exposed to sunlight. For best quality, keep onions in a dark area out of sunlight.
Rough handling may cause bruising, especially with spring/summer onions. To prevent bruising, keep handling to a minimum; do not drop shipping containers on the floor.
