Monsanto has said that we don't have a receptor for the toxin in their GMO food.
Never think that a bacterial toxin is a harmless thing however. It doesn't matter if it is naturally occurring or not, all toxins - with a working receptor - will produce a range of symptoms as a response, such as inflammation, fever, etc.
That is in fact why they are called toxins.
Finally, it is worth noting that much of what Monsanto claimed about this has been proven wrong. For instance they said the toxin would break down in the (human, extremely low pH) stomach, but it is not doing that.
This story is just beginning.
You statement says to me, very clearly, that you are not a toxicologist. There is nothing out there that is not toxic. Name anything; any element, compound, or mixture that is not toxic. Pure water is toxic if the dose is sufficient. Go ahead, name one that is not toxic? See Paracelsus—this man recognized this truth around 1500 AD. We all live in a toxic world, there is no escape. You must get over your extreme views. The leftist nutbags are here to attack every private enterprise using deceit, lies, and distortions. I’m a scientist, not a leftist or one of their corrupt lawyers in it for the money.
Not really why they are called toxins. There are a host of toxins that cause neither fever or inflammation. They simply put an end to metabolism, you die.
