You are absolutely right Don, in the United States, the Food and Drug Administration has deemed it safe and for the most part, it is but of course there is a "but"!
The stuff was called into question starting in the 80s and has been studied multiple times since both in t he food production and medical community and there have been many consumer based efforts to get it removed from the food chain. I steer clear of it due to the history of cancer in my family and I try to do the same with commercially processed foods. Like we say here, you do you, it's your beer! I'm not telling anyone that I'm right and they are wrong, I'm putting my conclusions and reasoning out there to further discussion and understand.
