Markoulatos et al., 2004 agree that in the United States, genetically modified food plants have been permitted for meal since 1992. In 1997, genetically modified soybeans represented estimated 10% of the total reaped in the United States and, in 2004, it increased to almost all of the soybean production. Nevertheless, some experts obey that Arvanitoyannis and Krystallis agree that new technologies for genetic modification are not yet accepted due to ethical issues.

So, if the companies produce genetically modified food crops to consumers may have the genetic problem.
