This happens whenever you vomit (you don't vomit any more than you do now). It is ACTUAL ground beef. It is not contaminated and is safe to eat.

To clarify a question I was asked in person: the ground beef is raw.

I urinate lots and vomit very rarely.

Plus, I really really don't want a bladder full of carbonated fluid. That's a recipe for disaster.

Of course, this brings up the social implications of drinking one's own urine, or eating one's own vomit (after cooking it, of course).

Urinating something drinkable would be a boon if you were lost in the desert or at sea. But since that's highly unlikely to occur, I agree that ground beef is better in day to day life for the reason's Bryan outlined.

Ack! Grammatical error (reason's) and no way to fix it. :(
