I'd eat the sausages if a human had fallen into the sausage machine; I probably wouldn't eat a thumb in my soup (but I would fish it out and eat the soup).

I also prefer to avoid aspartame, because it gives me headaches.

Arsenic is OK in trace quantities - but builds up in the system. There is an antidote. If you work in a chem. lab researching arsenic compounds you go through a lot of the antidote. Then the spooks show up to see why you are going through so much of it... (apparently troo story of someone my Dad knew who was doing a PhD on arsenic compounds).
