USDA regulations:

Organic crops. The USDA organic seal verifies that irradiation, sewage sludge (milorganite), synthetic fertilizers, prohibited pesticides, and genetically modified organisms were not used.

Organic livestock. The USDA organic seal verifies that producers met animal health and welfare standards, did not use antibiotics or growth hormones, used 100% organic feed, and provided animals with access to the outdoors.

Organic multi-ingredient foods. The USDA organic seal verifies that the product has 95% or more certified organic content. If the label claims that it was made with specified organic ingredients, you can be sure that those specific ingredients are certified organic.

• Organic certification requires that farmers and handlers document their processes and get inspected every year.
• Organic on-site inspections account for every component of the operation, including, but not limited to, seed sources, soil conditions, crop health, weed and pest management, water systems, inputs, contamination and commingling risks and prevention, and record-keeping.
• Tracing organic products from start to finish is part of the USDA organic promise.
