Well, as with cake batter, there are raw eggs in the mix. Don't know about "worms", but you might come down with a case of the runs.
It’s salmonella. Any chicken (or reptile since birds and reptiles are so similar) can have the salmonella bacteria, which doesn’t seem to harm them. It can make us very sick. That is why we shouldn’t eat raw eggs, even from healthy chickens in your backyards. Some people like to, but they do take that risk.
