Agriculture officials from several states have pressed the federal government to halt deliveries of packages that may contain the seeds as states continue to be inundated by reports from people across the U.S. who have received them. Officials are concerned the seeds could introduce weeds, pests or diseases that could harm U.S. agriculture.
The U.S. Department of Agriculture said last week it had so far identified 14 species of seeds, from mustard and morning glory to cabbage, rosemary and roses. As of late Wednesday, there was no indication the seeds carry pests or diseases, according to the USDA. Several states say they have identified seeds of weed species that could pose a threat to crops and native plants.
“We are working closely with [U.S. Customs and Border Protection] to intercept illegally imported seed packages,” a USDA spokesperson said in a statement. “We’re also working with other federal authorities, the U.S. Postal Service, express carriers, and online marketplaces to stop future deliveries.”
