Genetically Modified sweet corn is genetically engineered to be herbicide resistant and to produce its own pesticide. Like most GMOs, genetically modified sweet corn has not been thoroughly tested to ensure that it is safe for consumption.
At this point in time, genetically modified tomatoes have been "removed" from the markets, due to people being unsure about eating them. Why? They were surprised by the fact that the tomatoes stayed ripe for more than 1 week+ what they would usually be ripe for. The modified tomatoes did not do anything more than stay fresh for longer, but since they were one of the first few GMO foods on the market, people were afraid to try them.
Genetically Modified squash has been grown worldwide since the late 1900s. Squash growth has increased anywhere from 20%-80% internationally since the absence of diseases found in them.
Since the start of the experiment, GMO squash consumption has increased rapidly, due to the fewer amounts of diseased crops.
