Grain weevils are not harmful to your health but not very pleasing to Americans to know they are eating them. There is no way to keep all bugs out of grain silos and mills. I would think organic grains go to the same silos and mills and have many more bugs in them then the non organic grains. The weevils are milled right in. How often are the mills checked for how many bugs are in the grain before milling? Not that often I would think.
