Unsolicited Seed Packages – What to Do

AmericanHort has reported unsolicited seed packets being received in the mail, often mislabeled and appearing to come from overseas. These seeds may carry invasive pests or diseases and pose serious threats to U.S. agriculture and native ecosystems. If you receive a package like this, do not open, plant, or discard the seeds. Keep all packaging, including mailing labels, and report the incident to the USDA’s Smuggling Interdiction and Trade Compliance (SITC) program by emailing SITC.Mail@usda.gov or visiting aphis.usda.gov/sitc. SITC will provide instructions on how to handle and safely dispose of the seeds.
