Oregon Revised Statutes Food and Other Commodities: Purity, Sanitation, Grades, Standards, Labels, Weights and Measures § 619.416

(1) Lamb, or the immediate container in which it is enclosed, which is produced and processed in Oregon and is offered for sale for human consumption, may be conspicuously labeled with a label not less than one inch in height and one and one-half inches in width in legible letters or figures of not less than three-sixteenths of an inch in height, with the words “Grown in Oregon.” If the immediate container is made of transparent material, the label may be placed inside the material if it is affixed so that it is easily readable by a consumer or purchaser. If the lamb is not enclosed in an immediate container, the label shall be placed on a tag securely fastened to the lamb.

(2) Lamb that is produced in Oregon and processed out-of-state may carry the “Grown in Oregon” label if the producer, processor and retailer voluntarily develop a system of tracking and are able to prove that lamb sold for human consumption carrying the “Grown in Oregon” label was produced in Oregon.

(3) Lamb that is not produced in Oregon may not carry the name Oregon, in any form, anywhere on the lamb or its immediate container.
