You should not use feces directly. It can contain a lot of bacteria. Best if composed a couple yrs.

"The defector, who had been shot five times while crossing Demilitarised Zone between the two countries, went through two rounds of surgery in South Korea due to his injuries. Dr. Lee Guk-jong found more than thirty parasites in the defector’s stomach and intestines, including “a parasite never seen in Koreans before.”
The parasites infecting Lee’s patient, including the as-yet-unknown one, are often contracted by eating produce fertilized with human manure. Roundworms block the intestine, which causes malnutrition and, in more serious cases, pancreatitis, appendicitis, and peritonitis. Lee told the BBC that his patient had “an enormous number” of worms infecting his gunshot wounds, and said he’s “never seen anything like this in my 20 years as a physician.”
And considering the open border to the south we are going to have a lot of these problems with some "immigrant" populations.
