I suspect some organic/heritage farmer out there could try some type of lawsuit if a gmo planted crop near his organic field contaminated his product.
So far, it works the other way around, Monsanto be suing all the little farmers, organic or no.
I believe there is a case brewing by some organic farmers that they cannot grow organic with GMO crops nearby because of pollination with the GMO. The court has already ruled against companies using ‘terminator’ genes that make the product of planted seed sterile.
This man is buying commodity beans. They have many uses besides feed. The elevator resells the beans to the highest bidder for whatever they need them for. Remember these are beans from many farmers and many varieties and some are not GMO. There could even be GMO seed the patent has run out on in the mix. He is buying a mixed up mess using it for seed. He is not buying pure GMO seed or a certain variety so I do not see where Monsanto has a claim. The farmer, on purchase of the commodity beans does not even know if the seeds will grow.
