I toured the factory in Hershey Pennsylvania when I was a kid, and I didn't see anyone vomiting except customers in the parking lot.
I just remembered something that seemed insignificant at the time: men wearing Hershey's coveralls would come out with fresh vomit pails, and bring the full ones back inside, for disposal I assume. Perhaps I'm just being naive?
