Agriculture officials are alarmed that unsolicited seed packets are being mailed to thousands, or possibly millions, of American households. It’s a phenomenon repeated in many states, with the seeds apparently being shipped from China and labeled “jewelry” in order to get through customs more easily. Shasta County Department of Agriculture has joined other officials who say the seeds should not be planted, opened, or even thrown away. Anyone who gets seeds they did not order should contact the Ag Department at 224-4949 and arrangements will be made to pick them up. County Ag Commissioner Rick Gurrola says they could be invasive species sent to devastate the environment, displace or destroy native plants and insects, severely damage crops and poison livestock.
