According to the Tacoma News Tribune July 27th edition residents of Utah, Virginia and Washington states have received unsolicited mailed packages of seeds apparently emanating from China. Since this time the problem has expanded to numerous states and to Canada.
State regulatory authorities have warned recipients not to plant seeds as they may contain plant pathogens or pests that may damage domestic crops.
The source of the packets of seeds and the reason why they were consigned, apparently at random is unknown.
