iBerkshires.Com reports random packages of seeds that appear to be from China and other countries have been appearing in mailboxes across the country. The U.S. Department of Agriculture and numerous agricultural agencies across the nation are warning  people not to plant what could be an invasive species.

The state Department of Agricultural Resources has been notified that several Massachusetts residents have received these unsolicited packages that appear to have originated in a foreign country and contain seeds.

While the exact types of seeds in the packages are unknown, the seeds are thought to be invasive plant species, and not believed to be harmful to humans or pets but could pose a significant risk to agriculture or the environment.

MDAR encourages residents who receive or have received an unsolicited package of seeds to not plant the seeds and immediately complete a form on MDAR's website to provide important information to state plant regulatory officials.
