Criminal is right. On many levels. I have never been able to come across any proof of this so who knows if its true or not, but a few months back had a discussion with someone about this and was told that it actually was a crime (felony) at one point in the US (late 1800s ) to put any seed oil (ie industrial waste) into food. Can only imagine the deals made and money changing hands to allow literal waste into the food back then.
