Human poop is bad because it can contain viruses, bacteria and parasites that may infect us. That's why we have developed an aversion to human poopoo.

But what about animal poop? Can they contain pathogens that can infect us and make us sick? I think most people have an aversion to animal poo too, but not to the same extend as to human poo, so maybe it can be bad, but not as bad as human poo? And we do use animal poo as fertilizer so surly it can't be bad?

What does the /sci/ence say about it?
