OUTHOUSES AND PIT LATRINES
Outhouses have odor problems, breed flies and possibly mosquitoes, and pollute groundwater. However, if the contents of a pit latrine have been filled over and left for a minimum of one year, there will be no surviving pathogens except for the possibility of roundworm eggs, according to Feachem. This risk is small enough that the contents of pit latrines, after twelve months burial, can be used agriculturally. Franceys et al. state, "Solids from pit latrines are innocuous if the latrines have not been used for two years or so, as in alternating double pits." 32
