I have seen research that put it even lower than that (.03 to .1 percent) but even at .6 percent its's exactly like you said a hang nail.  The highest estimate I have seen has deaths from AN at 500 with the more likely number under 200 and probably under a 100.  This is a family tragedy, not a public health issue.  Yet we treat it like we are Venice in the middle of the Black Death in 1350.
