Final answer:
Oregon relies on the Organic Materials Review Institute (OMRI) and the Washington State Department of Agriculture (WSDA) Organic Food Program as certifying agents for organic operations.
Step-by-step explanation:
Oregon relies on two certifying agents to certify operations as organic: the Organic Materials Review Institute (OMRI) and the Washington State Department of Agriculture (WSDA) Organic Food Program.
OMRI is a nonprofit organization that reviews and publishes lists of products allowed for organic production. The WSDA Organic Food Program is a state program that certifies and regulates organic food production in Washington state, which includes certifying operations in Oregon.
These certifying agents ensure that organic operations meet the standards set by the U.S. Department of Agriculture (USDA) for organic labeling, which include using cultural, biological, and mechanical practices that support the cycling of on-farm resources, promoting ecological balance, and conserving biodiversity.
