If Patented GMO Seeds Accidentally Grow on Your Property, You Could Be Sued
Like many of the fears about GMOs, this is one that has a germ of truth in it. In 1999, agribusiness giant Monsanto sued a Canadian organic canola farmer, Percy Schmeiser, for growing the company's pesticide-tolerant canola without paying the required fees. The farmer, in his defense, argued that he hadn't planted any of the company's GMO canola seeds, and that they must have blown onto his property.
An NPR journalist who investigated the issue of windblown seeds in 2012, reported that he didn't find any cases where Monsanto had sued anyone over trace amounts of seeds introduced through cross-pollination [source: Charles].
