Agriculture officials in multiple states, including Colorado, have issued warnings about unsolicited shipments of foreign seeds and advised people not to plant them over concerns that they could be an invasive plant species.
The Colorado Department of Agriculture said Monday that they have received numerous reports from across the state of people receiving unsolicited packages of seeds in the mail. The packages appear to have originated from China and other countries, and are labeled as containing jewelry or other items.
Unsolicited seeds could be invasive species, could contain noxious weeds, could introduce diseases to local plants, or could be harmful to livestock.
Invasive species and noxious weeds can displace native plants and increase costs of food production. All foreign seeds shipped to the United States should have a phytosanitary certificate which guarantees the seeds meet U.S. requirements.
Any Coloradan who receives an unsolicited package of seeds should:
- Immediately contact the Colorado Department of Agriculture’s Plant Industry Division by emailing firstname.lastname@example.org or calling 303-548-5333, or contact the APHIS State plant health director.
- Hold onto the seeds in their original packaging, including the mailing label, until someone from the Colorado Department of Agriculture or APHIS contacts you with further instructions.
- Avoid planting seeds from unknown origins, and do not put the seeds in the trash, where they could ultimately end up in the landfill and then sprout.
