Disclosure: i grew up on a farm, so i remember ripping/planting and harvesting. the risks of invasive species or diseased species are very real, and i suspect the concern here is that a seed recipient in proximity to a farmland could potentially introduce a pathogen or aberrant crop into the field. The introduction of castor beans into a corn crop for example can contaminate hundreds of tons of grain. The united states is massively dependent on a monoculture of corn, soy, and wheat. Its a dangerous gamble, but the profits and savings from doing this are enormous. These crops are groomed to be disease and drought resistant, however they are not invincible. Paranoia that random seeds from export controlled countries could somehow destroy a harvest is i think at least somewhat warranted.
