“Seeds sold in Pennsylvania are rigorously tested to ensure that they are genetically pure and regulated to ensure that what’s on the label is what’s in the package,” Secretary Redding said. “Planting seeds without knowing what they are can wreak havoc with our environment, destroy agricultural crops and incur costly control efforts for years to come.”

Officials say this is part of a scam called “brushing,” meant to boost a company’s online sales by shipping a company package to an actual address. Someone will then pretend they received the “product” and give it a positive review. Officials say that packages normally are empty based on past scams, but in this case, the packages have unlabeled seeds.
