Livanian beets were a type of food that Morn shipped. They began to rot if not used within a certain length of time. When Quark inherited all of Morn's assets in 2374, practically the only thing of any value he found (prior to discovering the thousand bricks of gold-pressed latinum) was a shipment of Livanian beets that had gone bad. (DS9: "Who Mourns for Morn?") According to the Star Trek Encyclopedia (4th ed., vol. 1, p. 483) , the "Livanian beet" was a variety of aromatic succulent root of a biennial Livanian herb used as a vegetable.
