I mean, its pretty easy to just go find some, you just have to wash it before you eat it
I don't think washing it will have much of an effect, given that the point of washing stuff is to be healthy which eating rust already negates
its to get the germs/dirt off, you don’t wash a cheeto to remove the unhealthy-ness
You don't wash a Cheeto at all though
What I mean is that I doubt that dirt would be the biggest health issue with that
