What guidance does FDA have for manufacturers of Edible Oils?

Olive oil is the edible oil expressed from the sound, mature fruit of the olive tree. Refined or extracted oil is not entitled to the unqualified name "olive oil."

Other vegetable oils should be labeled by their common or usual names, such as cottonseed, sunflower, peanut, and sesame. Mixtures of edible oils should be labeled to show all the oils present and the names should be listed on the labels in the descending order of predominance in the product. Terms such as "vegetable oil" or "animal shortening" are permitted, provided that the source of each oil or fat used in the product is disclosed" (21 CFR 101.4(b)(14)). Pictures, designs, or statements on the labeling must not be misleading as to the kind or amount of oils present or as to their origin.

Cod liver oil is a drug as well as a food since it is recognized in the United States Pharmacopeia (USP). Its value as a food whether intended for human or animal use depends mainly on its vitamin D content. Articles offered for entry as cod liver oil must comply with the identity standard prescribed by the USP and conform to the other specifications set forth in that official compendium.
