It's not unexpected, considering that humans tend to be found around civilization, and the majority of dust is human skin.

Would you have a problem with this if people said that a hotdog had picked up detectable amounts of particulate matter from the air?

I'd say this depends on how that dna got there, and how much. Is this just minute dna from fingerprints or the presence of humans, or is it something more severe. I don't expect all food to be prepared in sterile clean rooms.

Why else would it bother me? I mean if people were being killed to make the hotdogs... but otherwise?

There are body parts that can be harvested from people, but regrow. (Liver and Blood for example.)

You'd be OK eating those? I wouldn't, I'd be grossed out.

Or is it just when it tiny minimal quantities? Which honestly everyone eats sometimes.
