Earlier quoted context omitted.
"The use of untreated human feces in agriculture poses significant health risks and has contributed to widespread infection with parasitic worms—a disease called helminthiasis, affecting over 1.5 billion people in developing countries." https://en.wikipedia.org/wiki/Human_feces
It's the same for using animal feces. There are ways to mitigate risk. https://pubs.acs.org/doi/10.1021/acs.est.7b02811
